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.

Abstract: A mask circuit masks a digital video signal so that a video signal of an analog video signal is not outputted for a predetermined period after the start of output of a horizontal synchronizing signal of the analog video signal. A period of masking the digital video signal by the mask circuit is set in a control register, and the control register transmits the masking period to the mask circuit. A digital video signal to analog video signal converting unit converts the digital video signal masked and outputted from the mask circuit into an analog video signal. Thus, by setting in the control register the period of masking the digital video signal until the video signal of the analog video signal is stabilized, a digital video encoder can output a stable video signal.
