  • Solid-state image sensor, imaging control method, signal processing method, and electronic apparatus
    Patent number: 10171750
    Abstract: The present technology relates to a solid-state image sensor, an imaging control method, a signal processing method, and an electronic apparatus that suppress the deterioration of image quality, which is caused by the difference of sensitivity between pixels. A solid-state image sensor includes: a pixel array unit including a plurality of pixels arranged, the plurality of pixels including a plurality of kinds of pixels, the plurality of kinds of pixels including a first pixel and a second pixel, the first pixel having the highest sensitivity, the second pixel having a sensitivity lower than the sensitivity of the first pixel; and a control unit that controls at least one of an analog gain and exposure time of/for the respective pixels depending on a ratio between the sensitivities of the first pixel and the second pixel. The present technology is applicable to a solid-state image sensor such as a CMOS image sensor.
