The infrared filter 60 is an infrared pass filter, that is, only infrared light transmitted to the infrared filter 60 can pass through the infrared filter 60. The ir filter 60 may be circular, rectangular, oval, or other shape that matches the mounting hole 202.

The array of photosensitive pixels 10 includes a plurality of photosensitive pixels 12.
Referring to fig. 5 and 6, the filter array 20 covers the photosensitive pixel array 10. The filter cell array 20 includes a plurality of filter cells 22. Each of the filter units 22 includes two infrared filter regions 222 and two color filter regions 224, and the infrared filter regions 222 and the color filter regions 224 in each of the filter units 22 are alternately disposed at intervals. Wherein the infrared filter area 222 only passes infrared light and filters out other light (e.g., visible light) so that the other light cannot pass, the infrared filter area 222 includes a plurality of infrared filter subunits 2222. The color filter region 224 passes only visible light and filters out other light (e.g., infrared light) so that the other light cannot pass. Specifically, the color filter area 224 includes a plurality of color filter subunits 2241, and the color filter subunit 2241 may be any one of a green filter subunit 2242, a blue filter subunit 2244, or a red filter subunit 2246. Among them, the green filter subunit 2242 passes only green light and filters other light so that other light cannot pass, the blue filter subunit 2244 passes only blue light and filters other light so that other light cannot pass, and the red filter subunit 2246 passes only red light and filters other light so that other light cannot pass. Each of the infrared light-filtering sub-units 2222 and the color light-filtering sub-units 2241 covers one of the photosensitive pixels 12, that is, each of the infrared light-filtering sub-units 2222, the green light-filtering sub-units 2242, the blue light-filtering sub-units 2244 and the red light-filtering sub-units 2246 covers one of the photosensitive pixels 12.
The photosensitive pixels 12 covered by the infrared filter region 222 constitute the iris recognition pixels 122, and the photosensitive pixels 12 covered by the color filter region 224 constitute the color image pixels 124. In other words, the photosensitive pixels 12 covered by the infrared filter region 222 are referred to as iris recognition pixels 122, and the photosensitive pixels 12 covered by the color filter region 224 are referred to as color image pixels 124. The iris recognition pixels 122 are capable of receiving infrared light and generating iris image signals including infrared pixel values, luminance values of the infrared light, and the like. Color image pixels 124 are capable of receiving visible light and producing color image signals that include color pixel values, luminance values of colored light, color values, and the like.
Each of the filter units 22 of the present embodiment covers 2 × 4 photosensitive pixels 12, specifically, each of the filter units 22 includes 2 infrared filter regions 222 and 2 color filter regions 224, and the infrared filter regions 222 and the color filter regions 224 are alternately disposed at intervals. Each color filter region 224 includes 2 × 1 color filter subunits 2241, and each infrared filter region 222 includes 2 × 1 infrared filter subunits 2222. That is, each of the filter units 22 includes 2 × 2 color filter subunits 2241 arranged in an array and 2 × 2 infrared filter subunits 2222 arranged in an array. The color filter subunits 2241 and the infrared filter subunits 2222 in the same row are alternately arranged at intervals.

The photosensitive pixels 12 covered by the infrared filter area 222 constitute the iris recognition pixels 122, that is, 2 × 2 photosensitive pixels 12 covered by the 2 × 2 infrared filter subunits 2222 are the iris recognition pixels 122. The output of 2 × 2 photosensitive pixels 12 covered by the infrared filter region 222 corresponds to an iris image signal. The photosensitive pixels 12 covered by the color filter region 224 form the color image pixels 124, that is, the 2 × 2 photosensitive pixels 12 covered by the color filter region 224 are the color image pixels 124. The output of the photosensitive pixels 12 covered by the color filter regions 224 corresponds to color image signals.
The control circuit 30 is connected to the array of photosensitive pixels 10. The control circuit 30 may be used to control the iris recognition pixels 122 to acquire iris image signals and to control the color image pixels 124 to acquire color image signals. The iris recognition pixels 122 are capable of receiving infrared light and generating iris image signals including infrared pixel values, luminance values of the infrared light, and the like. The output of the photosensitive pixels 12 covered by the infrared filter region 222 corresponds to the infrared pixel value, that is, the output of the iris identification pixels 122 corresponds to the infrared pixel value. Color image pixels 124 are capable of receiving visible light and producing color image signals that include color pixel values, luminance values of colored light, color values, and the like. The output of the photosensitive pixels 12 covered by the color filter regions 224 corresponds to color pixel values, i.e., the output of the color image pixels 124 corresponds to color pixel values.
The control circuit 30 may also be used to control the iris recognition pixels 122 to acquire iris image signals, and to control the color image pixels 124 to acquire color image signals in conjunction with the iris recognition pixels 122. When the control circuit 30 controls the color image pixels 124 and the iris identification pixels 122 to collectively acquire a color image, the control circuit 30 is configured to subtract the adjacent infrared pixel values from the color pixel values to obtain actual pixel values of the color image pixels of the color image.
The electronic device 300, the camera module 301 and the lens module 200 of the embodiment of the invention drive the infrared filter 60 to move through the first driving member 70, so that the infrared filter 60 can selectively shield the mounting hole 202 or open the mounting hole 202, and thus all light rays entering from the light passing hole 52 can selectively pass through or only infrared light rays of all light rays entering from the light passing hole 52 can pass through.
The electronic device 300 of the embodiment of the invention also has the following beneficial effects: first, the filter unit array 20 of the image sensor 100 includes an infrared filter region 222 and a color filter region 224, so that light entering the iris recognition pixels 122 mainly includes infrared light and light entering the color image pixels 124 mainly includes visible light, so that the image sensor 100 can obtain iris image signals from the iris recognition pixels 122 and color image signals from the color image pixels 124; or the image sensor 100 can obtain color image signals from the color image pixels 124 and the iris identification pixels 122 together, and then the image sensor 100 can realize both iris image acquisition and color image acquisition, thereby avoiding the need for the iris image sensor and the color image sensor at the same time, not only reducing the cost of the electronic device, but also freeing up space for setting other functional units.
Second, the infrared filter regions 222 and the color filter regions 224 in each filter unit 22 are alternately disposed at intervals, that is, the infrared filter regions 222 and the color filter regions 224 are close to each other, so that the control circuit 30 is used to subtract the color pixel values from the adjacent infrared pixel values to obtain the actual pixel values of the color image pixels of the more accurate color image.
