The structural representation of a kind of sensor devices embodiment that Fig. 1 provides for the embodiment of the present application, this sensor devices can comprise:
Multiple first photosensitive unit 101 and multiple second photosensitive unit 102.
Wherein, multiple first photosensitive unit 101 is positioned at the edge of sensor devices;
Multiple second photosensitive unit 102 is arranged in sensor devices, does not comprise other regions of described multiple first photosensitive unit 101 region.
Wherein, the size of the first photosensitive unit 101 is greater than the size of the second photosensitive unit 102.
Sensor devices is mainly used in the image capture devices such as digital camera.Sensor devices is made up of multiple photosensitive unit.In CCD, the compositions such as the main diode of photosensitive unit, control signal circuit and charge transport circuit.
Photosensitive unit can convert light to electric charge, thus forms the electronic image corresponding to scenery.And in sensor devices, the at least corresponding pixel (Pixels) of each photosensitive unit, in a kind of possibility implementation, each photosensitive unit can respond to R (red, red), in G (green, green) and B (blue, blue) primaries one.
Conveniently clear description, in the embodiment of the present application, is divided into the first photosensitive unit and the second photosensitive unit, represents the second photosensitive unit in Fig. 1 with the hypographous part of tool by the photosensitive unit in sensing device, and blank part represents the first photosensitive unit.
Each first photosensitive unit or each the second photosensitive unit can to respond in R, G and B primaries one, according to the difference required image color, the photosensitive unit can responding to different light rays can have different distributions, same as the prior art, do not repeat one by one at this, it should be noted that there is in Fig. 1 the photosensitive unit of same shape or structure, do not represent the light of their induction same primary color.
Also it should be noted that, the arrangement mode of the first photosensitive unit in Fig. 1, and the arrangement mode of the second photosensitive unit is only a kind of possible implementation, only need meet the first photosensitive unit is positioned at photosensitive miracle edge.
Due in prior art, when utilizing the image capture devices such as digital camera to carry out image taking, the light of coming in from camera lens usually in the middle of brighter, and edge is comparatively dark, and this just causes in the middle of the image taking out brighter, and edge is comparatively dark, the quality of effect diagram picture.And adopt the sensor devices of the embodiment of the present application, at the edge of sensor devices, larger-size first photosensitive unit is set, and the size of second photosensitive unit in other regions can be arranged according to normal size, thus make the light that the first photosensitive unit can experience more, when image exports, corner becomes the first large photosensitive unit, from the second adjacent photosensitive unit, obtain image content information, then output brightness information, brightness and the resolution of this sampled images are taken into account.Thus it is comparatively dark and affect the also darker problem in image border to compensate for the plain edge edge of coming in due to camera lens to a certain extent, improves the brightness of image border, thus namely improves the quality of image.
Wherein, because the requirement to image of different images collecting device is different, or it is different from the camera lens that sensor devices mates, the light of coming in from camera lens is usually middle brighter, and edge may be only darker in some position, therefore this first photosensitive unit specifically can be positioned at the predeterminated position at sensor devices edge, and this predeterminated position is the more weak place of light that sensor devices receives.
As a kind of possible implementation, in order to adapt to different image capture devices and camera lens etc., this first photosensitive unit can specifically comprise 4, lay respectively at four corners of sensor devices, as shown in fig. 1,4 the first photosensitive units of four corners for being positioned at sensor devices namely illustrated.Certainly, the application not only limits this kind of implementation.
Wherein, these 4 first photosensitive units can be specifically the photosensitive units responding to same primitive color light, such as, be G primitive color light.
As a kind of possible implementation, the size of multiple first photosensitive unit can be identical, and the size of multiple second photosensitive unit is also identical, and this first sensing unit is of a size of 4 times of described second photosensitive unit.
It should be noted that, first photosensitive unit is of a size of how many times of the second photosensitive unit size, this concrete multiple can according in actual conditions, the optical curve of image capture device camera lens is determined, thus in conjunction with the light that camera lens enters, and this first photosensitive unit, the light that the first photosensitive unit is received can make up the brightness of the image border that image capture device exports, and the brightness of whole image is consistent substantially.
Certainly, the size of the plurality of first photosensitive unit also can be different, can receive the number of the light of coming in from camera lens according to the first position, corresponding edge, photosensitive unit position, the size of first photosensitive unit at the marginal position place that the light received is many can be less than the size of first photosensitive unit at the few marginal position place of the light that receives.
Certainly, as the implementation that another kind is possible, the size of multiple second photosensitive unit can be different, and the size of the first photosensitive unit can be identical, also can be different, but the size of any one the first photosensitive unit is greater than the size of any one the second photosensitive unit.
The embodiment of the present application additionally provides the image output method based on the sensor devices described in above-described embodiment, the concrete structure of this sensor devices can be shown in Figure 1, be made up of the first photosensitive unit and the second photosensitive unit, the first photosensitive unit is positioned at the edge of described sensor devices; Second sensing unit is arranged in other regions that described sensor devices does not comprise described first photosensitive unit region; The size of the first photosensitive unit is greater than the size of described second photosensitive unit.
As described in Figure 2, the method can comprise following step:
201: obtain the second monochrome information and the second image content information by the second photosensitive unit, obtain the second displaying contents, and export at second area.
202: obtain the first monochrome information by the first photosensitive unit.
203: combine described second image content information of second photosensitive unit adjacent with the first photosensitive unit and described first monochrome information, obtain the first displaying contents, and export in first area.
Wherein, described first area is positioned at the edge of described second area.
When the sensor devices that image capture device utilizes the embodiment of the present application to provide carries out IMAQ, the first photosensitive unit and the second photosensitive unit are respectively used to obtain brightness and image content information, to form the image of collection.
First photosensitive unit is for obtaining the first monochrome information and the first image content information, and the second photosensitive unit is for obtaining the second monochrome information and the western Sydney of the second picture material.
Second photosensitive unit, according to the second monochrome information obtained and the second image content information, can obtain the second displaying contents of image, and exports at second area.
And the first photosensitive unit mainly obtains the second monochrome information, according to the first monochrome information obtained, and the second image content information that combination second photosensitive unit adjacent with the first photosensitive unit obtains, the first displaying contents can be obtained, export in first area.
First area and second area refer to the region in the image of formation, and the image obtained by sensor devices is primarily of first area and second area composition, and this first area is positioned at the edge of second area.
Size due to the first photosensitive unit is greater than the size of the second photosensitive unit, more light can be received, thus the brightness of first area can be improved, and be obtain according to the second image content information of the second photosensitive unit activity adjacent with the first photosensitive unit by the first displaying contents of the first photosensitive unit activity, avoid the first photosensitive unit due to size larger, cause the coarse problem of picture material obtained, thus make the final image formed take into account brightness and resolution, improve the quality of image.
