具体实施方式detailed description
下面详细描述本发明的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本发明的实施方式，而不能理解为对本发明的实施方式的限制。Embodiments of the present invention are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary, are only for explaining the embodiments of the present invention, and should not be construed as limiting the embodiments of the present invention.
请参阅图1，本发明实施方式的控制方法，用于控制成像装置采用第一对焦模式或第二对焦模式对焦。第一对焦模式为反差对焦模式。Please refer to FIG. 1 , the control method according to the embodiment of the present invention is used to control the imaging device to focus in the first focus mode or the second focus mode. The first focus mode is a contrast focus mode.
控制方法包括以下步骤：The control method includes the following steps:
S10，获取成像装置的图像传感器的感光度；S10, acquiring the sensitivity of the image sensor of the imaging device;
S20，判断感光度是否大于预定阈值；及S20, judging whether the sensitivity is greater than a predetermined threshold; and
S30，在感光度大于预定阈值时控制成像装置采用第二对焦模式对焦。S30. Control the imaging device to focus in the second focus mode when the sensitivity is greater than a predetermined threshold.
请参阅图2，本发明实施方式的控制装置100包括获取模块10、判断模块20及第一控制模块30。作为例子，本发明实施方式的控制方法可以由本发明实施方式的控制装置100实现，可应用于电子装置1000，电子装置1000可以包括控制装置100及成像装置200。Referring to FIG. 2 , the control device 100 according to the embodiment of the present invention includes an acquisition module 10 , a judgment module 20 and a first control module 30 . As an example, the control method in the embodiment of the present invention can be realized by the control device 100 in the embodiment of the present invention, and can be applied to the electronic device 1000 , and the electronic device 1000 can include the control device 100 and the imaging device 200 .
其中，本发明实施方式的控制方法的步骤S10可以由获取模块10实现，步骤S20可以由判断模块20实现，而步骤S30可以由第一控制模块30实现。也即是说，获取模块10用于获取成像装置200的图像传感器的感光度。判断模块20用于判断感光度是否大于预定阈值。而第一控制模块30用于在感光度大于预定阈值时控制成像装置200采用第二对焦模式对焦。Wherein, step S10 of the control method in the embodiment of the present invention can be implemented by the acquiring module 10 , step S20 can be implemented by the judging module 20 , and step S30 can be implemented by the first control module 30 . That is to say, the obtaining module 10 is used to obtain the sensitivity of the image sensor of the imaging device 200 . The judging module 20 is used for judging whether the sensitivity is greater than a predetermined threshold. The first control module 30 is used for controlling the imaging device 200 to focus in the second focus mode when the sensitivity is greater than a predetermined threshold.
具体地，反差对焦模式根据焦点处画面的对比度变化，寻找对比度最大时的镜头位置。当所拍摄的图像对比度最大时，成像最清晰，即实现对焦。可以理解，在对比度小，例如低光环境中，被摄场景的对比度较低，反差对焦模式难以找到对比度最大的镜头位置从而导致对焦效果不佳甚至对焦失败。Specifically, in the contrast focusing mode, according to the contrast change of the image at the focal point, the lens position with the maximum contrast is searched for. When the contrast of the captured image is the largest, the imaging is the clearest, that is, the focus is achieved. It is understandable that in a low-contrast environment, such as a low-light environment, the contrast of the scene to be photographed is low, and it is difficult to find the lens position with the highest contrast in the contrast focusing mode, resulting in poor focusing effect or even focusing failure.
环境亮度可以由图像传感器成像时所采用的感光度(ISO)来判断，通常在低光环境中图像传感器所采用的感光度将大于在高光环境中的感光度。例如可以800为临界值，也即是预定阈值，当感光度大于800时为低光环境，而当感光度小于800时为高光环境。The ambient brightness can be judged by the sensitivity (ISO) adopted by the image sensor for imaging. Generally, the sensitivity adopted by the image sensor in a low-light environment will be greater than that in a high-light environment. For example, 800 may be a critical value, that is, a predetermined threshold. When the sensitivity is greater than 800, it is a low-light environment, and when the sensitivity is less than 800, it is a high-light environment.
拍照时，用户开启电子装置1000进入相机应用，此时成像装置采用第一对焦模式，即反差对焦模式。在一些示例中，用户将感光度设置为自动模式，成像装置200将根据环境光的亮度及系统设定自动调节感光度。在另外一些示例中，感光度设置为手动模式时，用户可根据拍摄需求调节感光度。获取模块10将获取调节后也即是用于成像的图像传感器采用的感光度。判断模块20判断将判断当前的感光度是否大于预定阈值。第一控制模块30在当前感光度大于预定阈值时控制成像装置200采用第二对焦模式对焦，即将反差对焦模式切换为其他在低光环境中对焦表现良好的对焦模式。When taking a picture, the user turns on the electronic device 1000 to enter the camera application. At this time, the imaging device adopts the first focusing mode, ie, the contrast focusing mode. In some examples, the user sets the sensitivity to an automatic mode, and the imaging device 200 will automatically adjust the sensitivity according to the brightness of the ambient light and system settings. In some other examples, when the sensitivity is set to the manual mode, the user can adjust the sensitivity according to shooting needs. The acquisition module 10 will acquire the adjusted photosensitivity adopted by the image sensor used for imaging. The judging module 20 judges whether the current sensitivity is greater than a predetermined threshold. The first control module 30 controls the imaging device 200 to use the second focus mode to focus when the current sensitivity is greater than a predetermined threshold, that is, to switch the contrast focus mode to another focus mode that performs well in low-light environments.
需要说明的是，预定阈值的设置通常可以在出厂时根据成像装置200的参数设置，当然也可以由用户在使用中根据成像装置200对焦时成功率进行设置。It should be noted that the setting of the predetermined threshold can generally be set according to the parameters of the imaging device 200 when leaving the factory, of course, it can also be set by the user according to the success rate of the imaging device 200 during use.
综上所述，本发明实施方式的控制方法、控制装置100及电子装置1000，根据图像传感器的感光度判断环境亮度，并在环境亮度较低也即是感光度较高时，将反差对焦切换至其他对焦模式，从而有效避免了在低光环境下反差对焦模式对焦效果不理想甚至对焦失败的情况。To sum up, the control method, the control device 100 and the electronic device 1000 according to the embodiments of the present invention judge the ambient brightness according to the sensitivity of the image sensor, and switch the contrast focus when the ambient brightness is low, that is, the sensitivity is high. to other focusing modes, thus effectively avoiding the situation that the focusing effect of the contrast focusing mode is not satisfactory or even the focusing fails in a low-light environment.
在某些实施方式中，电子装置1000可以是手机或平板电脑等具有拍照功能的电子终端。而成像装置200包括前置或/及后置相机。In some implementations, the electronic device 1000 may be an electronic terminal with a camera function, such as a mobile phone or a tablet computer. The imaging device 200 includes a front camera or/and a rear camera.
可以理解，电子装置1000包括但不限于本实施方式的示例。It can be understood that the electronic device 1000 includes but not limited to examples of this embodiment.
在某些实施方式中，第二对焦模式为激光对焦模式。In some embodiments, the second focus mode is a laser focus mode.
在这样的实施方式中，成像装置200通常包括激光测距装置。激光对焦模式主要利用红外光集中性强不易扩散的特性，通过记录红外光从激光测距装置发射出来，经过目标表面反射，最后被接收的时间差，由图像信号处理器来计算目标到成像装置的距离。该距离即为对焦过程中的物距，再根据镜片模组的焦距计算出所需要调整的像距的具体数值进而调整对焦位置，实现对焦。In such embodiments, imaging device 200 typically includes a laser ranging device. The laser focus mode mainly utilizes the characteristics of strong concentration of infrared light and is not easy to diffuse. By recording the time difference when infrared light is emitted from the laser distance measuring device, reflected by the target surface, and finally received, the image signal processor calculates the distance from the target to the imaging device. distance. This distance is the object distance in the focusing process, and then calculate the specific value of the image distance that needs to be adjusted according to the focal length of the lens module, and then adjust the focusing position to achieve focusing.
特别地，激光对焦模式在低照度环境中相对其他对焦模式对焦速度更快并且对焦成功率更高。In particular, the laser focus mode has a faster focus speed and a higher focus success rate than other focus modes in a low-light environment.
如此，可利用激光对焦模式在低光环境中良好的对焦表现，一来避免在该场景中反差对焦模式不理想的对焦效果，二来可以提高对焦速度，使用户获得在低光环境下良好的拍摄体验。In this way, the good focusing performance of the laser focus mode in low-light environments can be used to avoid the unsatisfactory focus effect of the contrast focus mode in this scene, and to increase the focus speed so that users can obtain good focus in low-light environments. Shooting experience.
在某些实施方式中，控制方法还包括步骤：In some embodiments, the control method also includes the steps of:
S40，接收用户输入以设定预定阈值。S40. Receive user input to set a predetermined threshold.
在某些实施方式中，控制装置100包括设定模块40。步骤S40可以由设定模块40实现。或者说，设定模块40用于接收用户输入以设定预定阈值。In some embodiments, the control device 100 includes a setting module 40 . Step S40 can be implemented by the setting module 40 . In other words, the setting module 40 is used for receiving user input to set the predetermined threshold.
具体地，设定模块40与成像装置200的用户界面连接，并接收用户的输入。设定模块40可以是触摸屏或按键，相应的，用户输入包括触屏或者按键的方式，增大或减小对应的数值。Specifically, the setting module 40 is connected with the user interface of the imaging device 200 and receives user input. The setting module 40 may be a touch screen or keys, and correspondingly, the user input includes touch screen or keys to increase or decrease the corresponding value.
如此，用户可以根据自己的使用习惯设定预定阈值，进而提高用户体验。In this way, the user can set a predetermined threshold according to his own usage habits, thereby improving user experience.
如上述实施方式的解释说明，预定阈值可在出厂时设置有默认值，默认值的设置可根据在出厂前进行试验以确定较佳地感光度预定阈值。当然在实际操作中用户可根据拍摄习惯对默认值进行修改并设置为新的预定阈值，以满足拍摄需求。As explained in the above embodiment, the predetermined threshold may be set with a default value at the factory, and the setting of the default value may be determined according to a test before leaving the factory to determine a better predetermined threshold of sensitivity. Of course, in actual operation, the user can modify the default value according to shooting habits and set it as a new predetermined threshold to meet shooting needs.
请参阅图3，在某些实施方式中，控制方法还包括以下步骤：Referring to Fig. 3, in some embodiments, the control method also includes the following steps:
S50，控制成像装置依次增大感光度；S50, controlling the imaging device to sequentially increase the sensitivity;
S60，在每个感光度下控制成像装置采用第一对焦模式进行多次对焦并记录对焦成功次数；及S60, controlling the imaging device to use the first focusing mode to perform multiple focusing and recording the number of times of successful focusing at each sensitivity; and
S70，根据每个感光度及对应的对焦成功次数确定预定阈值。S70. Determine a predetermined threshold according to each sensitivity and the corresponding number of times of successful focusing.
请参阅图4，在某些实施方式中，控制装置100还包括第二控制模块50、第三控制模块60及确定模块70。步骤S50可以由第二控制模块50实现，步骤S60可以由第三控制模块60实现，而步骤S70可以由确定模块70实现。或者说，第二控制模块50用于控制成像装置200依次增大感光度。第三控制模块60用于在每个感光度下控制成像装置200采用第一对焦模式进行多次对焦并记录对焦成功次数。确定模块70用于根据每个感光度及对应的对焦成功次数确定预定阈值。Referring to FIG. 4 , in some implementations, the control device 100 further includes a second control module 50 , a third control module 60 and a determination module 70 . Step S50 can be implemented by the second control module 50 , step S60 can be implemented by the third control module 60 , and step S70 can be implemented by the determination module 70 . In other words, the second control module 50 is used to control the imaging device 200 to increase the sensitivity sequentially. The third control module 60 is configured to control the imaging device 200 to use the first focusing mode to perform focusing multiple times at each sensitivity and record the number of times of successful focusing. The determining module 70 is configured to determine a predetermined threshold according to each sensitivity and the corresponding number of times of successful focusing.
可以理解，在实际拍摄中预定阈值可能与出厂设置时存在偏差，也即是在某些示例中，当感光度小于预定阈值时，仍有可能在采用第一对焦模式对焦失败。控制装置100可通过对采用第一对焦模式对焦成功时感光度进行统计以对原有预定阈值进行调整，如此，可以通过测试的方式确定更准确预定阈值，使用户获得良好的对焦体验。It can be understood that the predetermined threshold may deviate from the factory setting in actual shooting, that is, in some examples, when the sensitivity is lower than the predetermined threshold, it is still possible to fail to focus in the first focusing mode. The control device 100 can adjust the original predetermined threshold by making statistics on the sensitivity when the focus is successful in the first focusing mode. In this way, a more accurate predetermined threshold can be determined through testing, so that the user can obtain a good focusing experience.
