本申请实施例涉及图像清理技术领域，尤其涉及一种图像留存期的配置方法、装置、介质及电子设备。The embodiments of the present application relate to the technical field of image cleaning, and in particular to a configuration method, device, medium, and electronic equipment for an image retention period.
背景技术Background technique
当前平安城市项目逐渐趋向于海量接入，大量前端图片接入的不确定性，还有图片接入的瞬时突发性，给图片存储清理带来了极大的困难。由于每天接入的图片总大小都不一定，当存储空间固定，留存期设置确定后，可能会出现留存期还未到达，存储空间已被占满的问题。这样会造成新的图片数据接入无法写入存储，最终导致数据接入失败。The current safe city project is gradually tending to mass access, the uncertainty of a large number of front-end image access, and the instantaneous and sudden nature of image access have brought great difficulties to image storage and cleaning. Since the total size of the pictures accessed every day is not constant, when the storage space is fixed and the storage period is set, there may be a problem that the storage space is full before the storage period is reached. This will cause the new picture data access to fail to be written to the storage, and eventually lead to data access failure.
当前图像留存期是手动配置的，固定不变。清理策略为：每天定时扫描存储容量，若所占用的存储空间满足开始清理的存储容量占比且也超过留存期，则开始清理最老的图片，按天清理，直到达到结束清理的存储容量占比后停止清理。The current image retention period is manually configured and fixed. The cleaning strategy is: scan the storage capacity regularly every day. If the occupied storage space meets the storage capacity ratio of the start cleaning and exceeds the retention period, then start to clean up the oldest pictures, and clean up on a daily basis until the storage capacity ratio of the end cleaning is reached. After that stop cleaning.
这种方式，图像留存期是固定的，无法满足图片大小和图片量动态变化造成的图片总大小突发情况下的图片存储。In this way, the image retention period is fixed, which cannot meet the image storage in the case of a sudden change in the total size of the image caused by the dynamic change of the image size and image volume.

实施例一Embodiment one
图1是本申请实施例一提供的图像留存期的配置方法的流程图，本实施例可适用于对图像留存期进行动态设置的情况，该方法可以由本申请实施例所提供的图像留存期的配置装置执行，该装置可以由软件和/或硬件的方式来实现，并可集成于用于存储空间清理的智能终端等设备中。Figure 1 is a flow chart of the configuration method of the image retention period provided in Embodiment 1 of the present application. This embodiment is applicable to the situation where the image retention period is dynamically set. This method can be determined by the image retention period provided in the embodiment of the application The configuration device is executed, and the device can be implemented by software and/or hardware, and can be integrated into devices such as smart terminals used for storage space cleaning.
如图1所示，所述图像留存期的配置方法包括：As shown in Figure 1, the configuration method of the image retention period includes:
S110、获取目标区域内拍摄设备采集的图像数据，确定样本数据；S110. Obtain the image data collected by the shooting device in the target area, and determine the sample data;
其中，拍摄设备可以是相机、前端IPC、摄像头等各种设备，用于采集图像数据，并将图像数据上传至存储设备进行存储。Wherein, the photographing device may be various devices such as a camera, a front-end IPC, and a camera, and is used for collecting image data and uploading the image data to a storage device for storage.
在本方案中，目标区域可以是指由所有拍摄设备的分布位置构成的区域。In this solution, the target area may refer to an area formed by the distribution positions of all shooting devices.
在本实施例中，每个拍摄设备上报的结构化属性数据中可以携带图像大小，如果拍摄设备上报的每条数据都携带了图像大小，可以根据上报的数据时间和图像大小，得出实际每个拍摄设备每天接入的图像大小和所有拍摄设备每天接入的图像总大小。并按周每天进行记录，将获得的图像数据作为样本数据。其中，图像大小用于表征图像文件占据存储空间的多少，比如文件大小100k，指的是这个图像文件占用存储空间大小是100KB。In this embodiment, the structured attribute data reported by each shooting device can carry the image size. If each piece of data reported by the shooting device carries the image size, the actual The size of images accessed by a shooting device every day and the total size of images accessed by all shooting devices every day. And record it every day of the week, and use the obtained image data as sample data. Wherein, the image size is used to represent how much storage space the image file occupies, for example, the file size is 100k, which means that the storage space occupied by the image file is 100KB.
S120、基于所述样本数据、预设总标准偏差和预设总置信度，计算得到目标区域置信区间，并基于所述目标区域置信区间和目标区域拍摄设备数量，确定目标区域图像留存期；其中，所述目标区域置信区间用于表征目标区域内拍摄设备采集的图像数据大小。S120. Calculate the confidence interval of the target area based on the sample data, the preset total standard deviation, and the preset total confidence level, and determine the target area image retention period based on the target area confidence interval and the number of shooting devices in the target area; wherein , the confidence interval of the target area is used to characterize the size of the image data collected by the shooting device in the target area.
其中，总标准偏差和总置信度可以根据图像数据的数量进行设置。例如，图像数据的数量为100，可以设置总标准偏差为10％；图像数据的数量为500，可以设置总标准偏差为5％；图像数据的数量为1200，可以设置总标准偏差为3％。其中，总置信度可以设置为90％。Wherein, the total standard deviation and the total confidence can be set according to the amount of image data. For example, if the number of image data is 100, the total standard deviation can be set to 10%; if the number of image data is 500, the total standard deviation can be set to 5%; Wherein, the total confidence level can be set as 90%.
在本方案中，目标区域置信区间可以用于表征目标区域内拍摄设备采集的图像数据大小，目标区域置信区间满足总置信度要求。例如，目标区域置信区间是(1000,2000)，即拍摄设备获得的图像数据的大小在1000-2000范围内。即目标区域置信区间为(1000,2000)，总置信度为90％。In this solution, the confidence interval of the target area can be used to represent the size of the image data collected by the shooting device in the target area, and the confidence interval of the target area meets the requirements of the total confidence. For example, the confidence interval of the target area is (1000, 2000), that is, the size of the image data obtained by the shooting device is within the range of 1000-2000. That is, the confidence interval of the target area is (1000, 2000), and the total confidence level is 90%.
可选的，假设目标区域内拍摄设备采集的图像数据其平均值为μ，总标准偏差为δ，总置信度为α，则目标区域置信区间为(μ-Zα/2σ,μ+Zα/2σ)。其中，Zα/2σ即为对应的总标准偏差。Optionally, assuming that the average value of the image data collected by the shooting equipment in the target area is μ, the total standard deviation is δ, and the total confidence is α, then the confidence interval of the target area is (μ-Zα/2 σ,μ+Zα/2 σ). Among them, Zα/2 σ is the corresponding total standard deviation.
其中，图像留存期可以用于表征存储设备中存储的图像保留期限。若所占用的存储空间满足开始清理的存储容量占比且也超过图像留存期时，则开始清理最老的图像。其中，开始清理的存储容量占比可以根据存储设备的容量进行设定。其中，图像留存期的配置需要满足最小留存期的要求。最小留存期可以根据存储设备的需求进行设定。Wherein, the image retention period may be used to represent the retention period of images stored in the storage device. If the occupied storage space satisfies the proportion of the storage capacity to be cleaned up and the image retention period is exceeded, the oldest image will be cleaned up. Wherein, the proportion of the storage capacity to be cleaned up can be set according to the capacity of the storage device. Among them, the configuration of the image retention period needs to meet the requirements of the minimum retention period. The minimum retention period can be set according to the requirements of the storage device.
可选的，假设目标区域拍摄设备数量为X，目标区域置信区间是(1000,2000)则接入图片总大小为1500X。假设分配的存储容量为Y，则目标区域图像留存期为Y/1500X。Optionally, assuming that the number of shooting devices in the target area is X, and the confidence interval of the target area is (1000, 2000), the total size of the access pictures is 1500X. Assuming that the allocated storage capacity is Y, the image retention period of the target area is Y/1500X.
在本实施例中，可以根据置信度高的目标区域置信区间来计算目标区域图像留存期，并设置目标区域图像留存期。一般而言，若目标区域图像置信区间往大了调，则目标区域图像留存期要减少；若目标区域置信区间往小了调，则目标区域图像留存期要增加。例如，目标区域图像置信区间(1000X,2000X)，一周内若超过四天的天数都落在该目标区域置信区间内，则认为初始估计的总置信度和目标区域置信区间是较为可靠的；若落在目标区域图像置信区间外的多，总置信度偏低，则认为初始估计的目标区域置信区间不可靠。In this embodiment, the target area image retention period may be calculated according to the target area confidence interval with high confidence, and the target area image retention period may be set. Generally speaking, if the confidence interval of the target region image is adjusted larger, the retention period of the target region image will be reduced; if the target region confidence interval is adjusted smaller, the retention period of the target region image will be increased. For example, the image confidence interval of the target area (1000X, 2000X), if more than four days in a week fall within the confidence interval of the target area, it is considered that the total confidence of the initial estimate and the confidence interval of the target area are relatively reliable; if If many fall outside the image confidence interval of the target area and the total confidence is low, the initially estimated confidence interval of the target area is considered to be unreliable.
目标区域置信区间是可靠的，则无需调整。If the target region confidence interval is reliable, no adjustment is required.
目标区域置信区间不可靠分为两种情况。若落在(0,1000X)中较多，则目标区域置信区间要往小调整，若落在(2000X，∞)中较多，则目标区域置信区间要往大调整。There are two cases where the target region confidence interval is unreliable. If it falls more in (0,1000X), then the confidence interval of the target area should be adjusted smaller; if it falls more in (2000X, ∞), the confidence interval of the target area should be adjusted larger.
已知所有拍摄设备每天接入的图像总大小，按照一定周期计算得出合理的目标区域置信区间，从而计算得出更为合理的图像留存期，实现动态调整图像留存期。Knowing the total size of images accessed by all shooting devices every day, a reasonable confidence interval of the target area can be calculated according to a certain period, so as to calculate a more reasonable image retention period and realize dynamic adjustment of the image retention period.
本申请实施例所提供的技术方案，获取目标区域内拍摄设备采集的图像数据，确定样本数据，基于样本数据、预设总标准偏差和预设总置信度，计算得到目标区域置信区间，并基于目标区域置信区间和目标区域拍摄设备数量，确定目标区域图像留存期。通过执行本技术方案，可以动态计算目标区域图像留存期。使得图像留存期更为合理，避免了出现未达到清理条件存储容量就占满的情况。The technical solution provided by the embodiment of the present application obtains the image data collected by the shooting equipment in the target area, determines the sample data, and calculates the confidence interval of the target area based on the sample data, the preset total standard deviation and the preset total confidence degree, and based on The confidence interval of the target area and the number of shooting devices in the target area determine the image retention period of the target area. By implementing the technical solution, the retention period of the image in the target area can be dynamically calculated. This makes the image retention period more reasonable and avoids the situation where the storage capacity is full before the cleaning condition is met.
实施例二Embodiment two
图2是本申请实施例二提供的图像留存期的配置过程的示意图，本实施例二在实施例一的基础上进行进一步地优化。具体优化为：基于所述目标区域置信区间和目标区域拍摄设备数量，确定目标区域图像留存期，包括：确定对目标区域内拍摄设备所属子区域的划分结果；确定至少两个子区域的图像置信区间和子区域内拍摄设备数量；其中，所述图像置信区间用于表征子区域内拍摄设备采集的图像数据大小；根据至少两个子区域的图像置信区间和子区域内拍摄设备数量，配置子区域图像留存期。其中，未在本实施例中详尽描述的内容详见实施例一。如图2所示，该方法包括以下步骤：FIG. 2 is a schematic diagram of the configuration process of the image retention period provided by the second embodiment of the present application. The second embodiment is further optimized on the basis of the first embodiment. The specific optimization is: based on the confidence interval of the target area and the number of shooting devices in the target area, determine the image retention period of the target area, including: determining the division result of the sub-area to which the shooting equipment belongs in the target area; determining the image confidence intervals of at least two sub-areas and the number of shooting devices in the sub-region; wherein, the image confidence interval is used to characterize the size of the image data collected by the shooting device in the sub-region; according to the image confidence interval of at least two sub-regions and the number of shooting devices in the sub-region, configure the sub-region image retention period . Wherein, details that are not described in detail in this embodiment can be found in Embodiment 1. As shown in Figure 2, the method includes the following steps:
S210、确定对目标区域内拍摄设备所属子区域的划分结果；S210. Determine the division result of the sub-area to which the shooting device belongs in the target area;
在本方案中，子区域可以是由部分拍摄设备的分布位置构成的区域。目标区域包括至少两个子区域。In this solution, the sub-area may be an area formed by the distribution positions of some shooting devices. The target area includes at least two sub-areas.
在本实施例中，可以根据拍摄设备采集的图像数据大小或者拍摄设备的分布位置对目标区域内的拍摄设备所属子区域进行划分。其中，对目标区域内的拍摄设备所属子区域可以预先进行划分，也可以实时进行划分。In this embodiment, the sub-area to which the photographing device belongs in the target area may be divided according to the size of the image data collected by the photographing device or the distribution position of the photographing device. Wherein, the sub-area to which the photographing device belongs in the target area may be divided in advance, or may be divided in real time.
在本技术方案中，可选的，确定目标区域内的拍摄设备所属的子区域的划分结果，包括：In this technical solution, optionally, determining the division result of the sub-area to which the shooting device in the target area belongs includes:
获取目标区域内拍摄设备的分布位置和采集的图像数据；Obtain the distribution position of the shooting equipment and the collected image data in the target area;
根据所述分布位置和图像数据，确定拍摄设备所属子区域的划分结果，得到至少两个子区域。According to the distribution position and the image data, the division result of the sub-area to which the shooting device belongs is determined, and at least two sub-areas are obtained.
在本方案中，已知每个拍摄设备每天接入的图像大小，我们可以将图像大小相近的拍摄设备划分为同一个小区域。例如，把图像大小为(0,1000)的划分为子区域1，图像大小为(1000,2000)的划分为子区域2，以此类推，划分为不同的子区域。其中，1个拍摄设备每天接入的图像大小也是不同的，所以按照图像大小相近的拍摄设备进行划分的子区域可能会随着时间的推移而发生改变，逐渐趋于稳定。In this solution, given the size of the images that each shooting device receives every day, we can divide the shooting devices with similar image sizes into the same small area. For example, the image size of (0,1000) is divided into sub-region 1, the image size of (1000,2000) is divided into
在本实施例中，一个区域内，人或车经过其中一个拍摄设备，大概率也会经过另外几个拍摄设备，利用该特性也可以将一定范围的拍摄设备划分到一个子区域，以此可划分得到不同的子区域1、子区域2等。优选的，可以基于拍摄设备的分布位置对拍摄设备所属子区域进行划分。划分过程中可以参考基于图像大小进行子区域的划分结果，得到最终的子区域划分。In this embodiment, if a person or vehicle passes by one of the shooting devices in an area, there is a high probability that they will pass by several other shooting devices. Using this feature, a certain range of shooting devices can also be divided into a sub-area, so that The division results in different sub-areas 1, sub-areas 2, and so on. Preferably, the sub-regions to which the shooting devices belong can be divided based on the distribution positions of the shooting devices. During the division process, the result of sub-region division based on the image size can be referred to to obtain the final sub-region division.
示例性的，图3是本申请实施例二提供的子区域划分的示意图，如图3所示，假设目标区域内有21个拍摄设备，按照分布位置将一定范围内拍摄设备进行划分为：区域1为设备1/2/3/4，区域2为设备8/9/11/12/13/17，区域3为设备18/19/21，区域4为设备5/6/7/10/14/15/16/20。Exemplarily, FIG. 3 is a schematic diagram of sub-area division provided by
按照图像大小可以将相近的拍摄设备划分为：区域1为设备1/21，区域2为设备2/3/4/8/9，区域3为设备5/6/10/15/16/17/18/19/20，区域4为设备7/11/12/13/14。According to the image size, similar shooting equipment can be divided into: area 1 is equipment 1/21,
根据分布位置划分为主，并结合图像大小划分，则最终的子区域划分为：区域1为设备1/2/3/4/8/9，区域2为设备7/11/12/13/14，区域3为设备17/18/19/21，区域4为设备5/6/10/15/16/20。According to the distribution position, combined with the image size, the final sub-area is divided into: area 1 is device 1/2/3/4/8/9,
通过对子区域进行划分，可以动态计算每个子区域的图像留存期。使得图像留存期更为合理，避免了出现未达到清理条件存储容量就占满的情况。By dividing sub-regions, the image retention period of each sub-region can be dynamically calculated. This makes the image retention period more reasonable and avoids the situation where the storage capacity is full before the cleaning condition is met.
S220、确定至少两个子区域的图像置信区间和子区域内拍摄设备数量；其中，所述图像置信区间用于表征子区域内拍摄设备采集的图像数据大小；S220. Determine the image confidence intervals of at least two sub-areas and the number of shooting devices in the sub-areas; wherein, the image confidence intervals are used to represent the size of image data collected by the shooting devices in the sub-areas;
在本方案中，可以基于子区域内拍摄设备采集的图像数据、以及预先确定的标准偏差和置信度，计算得到子区域置信区间，以用于表征该子区域内拍摄设备采集的图像数据大小。其中，标准偏差和置信度可以根据图像数据的数量进行设置。In this solution, based on the image data collected by the shooting device in the sub-region, and the predetermined standard deviation and confidence level, the confidence interval of the sub-region can be calculated to characterize the size of the image data collected by the shooting device in the sub-region. Among them, the standard deviation and the confidence level can be set according to the amount of image data.
其中，不同子区域内拍摄设备数量是不同的，可以根据子区域的划分结果确定各个子区域内拍摄设备数量。Wherein, the number of shooting devices in different sub-regions is different, and the number of shooting devices in each sub-region can be determined according to the division result of the sub-regions.
S230、根据至少两个子区域的图像置信区间和子区域内拍摄设备数量，配置子区域图像留存期。S230. Configure a sub-region image retention period according to the image confidence intervals of at least two sub-regions and the number of shooting devices in the sub-regions.
在本方案中，图像置信区间大的子区域所需的存储空间要大，那么可以给该子区域设置更大的图像留存期；图像置信区间小的子区域所需的存储空间要小，那么可以给该子区域设置更小的图像留存期。In this scheme, the storage space required for a sub-region with a large image confidence interval is large, so a larger image retention period can be set for this sub-region; the storage space required for a sub-region with a small image confidence interval is small, then A smaller image retention period can be set for this sub-region.
在本实施例中，可以将至少两个子区域的图像置信区间和子区域内拍摄设备数量进行加权求和，构建待求解图像留存期方程，配置各个子区域的图像留存期。In this embodiment, the image confidence intervals of at least two sub-regions and the number of shooting devices in the sub-regions can be weighted and summed to construct an image retention period equation to be solved, and configure the image retention period of each sub-region.
在本技术方案中，可选的，根据所述图像置信区间和子区域内拍摄设备数量，配置子区域图像留存期，包括：In this technical solution, optionally, according to the image confidence interval and the number of shooting devices in the sub-area, configure the sub-area image retention period, including:
根据所述图像置信区间，确定子区域置信参数；Determine sub-region confidence parameters according to the image confidence interval;
基于所述子区域置信参数、拍摄设备数量、目标区域图像留存期以及目标区域置信参数，配置子区域图像留存期。Based on the sub-region confidence parameters, the number of shooting devices, the target region image retention period, and the target region confidence parameters, the sub-region image retention period is configured.
在本方案中，子区域置信参数可以是指子区域图像置信区间的中间值。例如，图像置信区间为(800，1200)，则子区域置信参数可以是1000。子区域图像置信区间的中间值能够代表该子区域内拍摄设备采集的图像数据的大小。In this solution, the subregion confidence parameter may refer to an intermediate value of the confidence interval of the subregion image. For example, if the image confidence interval is (800, 1200), then the sub-region confidence parameter may be 1000. The median value of the image confidence interval of the sub-region can represent the size of the image data collected by the shooting device in the sub-region.
其中，拍摄设备数量包括子区域拍摄设备数量和目标区域拍摄设备数量。Wherein, the number of shooting devices includes the number of shooting devices in the sub-area and the number of shooting devices in the target area.
在本实施例中，目标区域置信参数可以是指目标区域图像置信区间的中间值。例如，目标区域图像置信区间为(1500,2000)，则目标区域置信参数可以是1750。目标区域置信区间可以根据目标区域内拍摄设备采集的图像数据以及预先确定的总标准偏差和总置信度进行计算得到。In this embodiment, the target region confidence parameter may refer to an intermediate value of the target region image confidence interval. For example, if the target region image confidence interval is (1500, 2000), then the target region confidence parameter may be 1750.

其中，预设留存期约束条件可以是指子区域的图像留存期需要满足的条件，可以根据目标区域图像留存期进行设置。例如，假设子区域图像留存期为z1、z2、z3、z4，目标区域图像留存期为Z，则留存期约束条件可以设置为z1<z2<Z，z4>z3>Z。Wherein, the preset retention period constraint condition may refer to a condition that the image retention period of the sub-area needs to meet, and may be set according to the image retention period of the target area. For example, assuming that the retention periods of sub-region images are z1, z2, z3, z4, and the retention period of target region images is Z, the retention period constraints can be set as z1<z2<Z, z4>z3>Z.
在本方案中，可以将各子区域置信参数和子区域拍摄设备数量进行加权求和，以及将目标区域置信参数、目标区域拍摄设备数量和目标区域图像留存期进行加权求和，共同构建待求解图像留存期方程。例如，假设目标区域包括4个子区域，目标区域内拍摄设备为X，目标区域图像留存期为Z，目标区域置信区间为(1500，2000)，目标区域置信参数为1750。再假设子区域1的拍摄设备数为x1，图像置信区间为(800,1200)；子区域2的拍摄设备数为x2，图像置信区间为(1200,1800)；子区域3的拍摄设备数为x3，图像置信区间为(1800，2200)；子区域4的拍摄设备数为x4，图像置信区间为(2200,2800)。每个子区域的图像留存期为z1、z2、z3、z4。构建的待求解图像留存期方程为：In this scheme, the weighted summation of the confidence parameters of each sub-region and the number of shooting devices in the sub-regions, and the weighted summation of the confidence parameters of the target region, the number of shooting devices in the target region, and the retention period of the image in the target region can be carried out to jointly construct the image to be solved Retention Equation.

Then assume that the number of shooting devices in sub-region 1 is x1, and the image confidence interval is (800, 1200); the number of shooting devices in
1000x1z1+1500x2z2+2000x3z3+2500x4z4＝1750XZ；1000x1z1+1500x2z2+2000x3z3+2500x4z4=1750XZ;

z1<z2<Z，z4>z3>Z；z1<z2<Z, z4>z3>Z;
其中，1000、1500、2000、2500分为为各个子区域的图像置信参数，基于图像置信区间确定的。z1<z2<Z，z4>z3>Z为预设留存期约束条件。Among them, 1000, 1500, 2000, and 2500 are divided into image confidence parameters for each sub-region, which are determined based on the image confidence interval. z1<z2<Z, z4>z3>Z is the default retention period constraints.
通过随机值代入法可以算出子区域1和子区域2要缩短多少天的图像留存期，子区域3和子区域4要增加多少天的图像留存期。The random value substitution method can be used to calculate how many days the image retention period of sub-region 1 and

其中，在配置子区域图像留存期后，若用户愿意牺牲非目标拍摄设备的图像留存期时长，希望目标拍摄设备所属子区域的图像留存期时长长一点，则可以根据预设配置规则调整子区域的图像留存期。Among them, after configuring the sub-area image retention period, if the user is willing to sacrifice the length of the image retention period of the non-target shooting device and wants the image retention period of the sub-region to which the target shooting device belongs to be longer, then the sub-region can be adjusted according to the preset configuration rules image retention period.
在本实施例中，可以将目标拍摄设备匹配留存期较长的小区域中的拍摄设备。如果匹配度高于90％，则不进行图像留存期调整；如果匹配度小于90％，可以将目标拍摄设备跟每个小区域中的拍摄设备进行匹配，若图像留存期缩短的小区域的匹配度有高于图像留存期增加的小区域的匹配度的情况，则将匹配度高的小区域的图像留存期随机增加到用户的期望值，而对应匹配度低的小区域就根据计算减小图像留存期。例如，子区域1的图像留存期为5天、子区域2的图像留存期为7天，目标拍摄设备所属子区域为子区域1，则可以根据用户期望值调整子区域1的图像留存期为7天，调整子区域2的图像留存期为5天。In this embodiment, the target shooting device can be matched with shooting devices in a small area with a long retention period. If the matching degree is higher than 90%, the image retention period adjustment will not be performed; if the matching degree is less than 90%, the target shooting device can be matched with the shooting device in each small area, if the matching of the small area with shortened image retention period If the matching degree is higher than the matching degree of the small area with increased image retention period, the image retention period of the small area with high matching degree is randomly increased to the user's expectation, and the corresponding small area with low matching degree is reduced according to the calculation. retention period. For example, if the image retention period of sub-area 1 is 5 days, the image retention period of
