Abstract: To reduce power consumption in a solid-state image sensor that measures a time. The solid-state image sensor includes a count unit, a count control unit, a clock unit, and an estimation unit. The count unit counts the number of times a photon has been incident within a predetermined exposure period, and outputs a count value. The count control unit performs control to stop the count unit and performs a request of time information in a case where the count value has reached a predetermined value before the predetermined exposure period elapses. The clock unit measures a time and outputs the time information in response to the request. The estimation unit estimates the number of incident times of a photon within the predetermined exposure period on the basis of the output time information.

Abstract: The present disclosure relates to a solid-state imaging element and an electronic apparatus, in which the number of wires controlling readout can be reduced in a case where a pixel signal of each pixel is read out in a predetermined order for each unit pixel region. The unit pixel region is configured by a plurality of pixels arranged in an array. A readout circuit is provided for each unit pixel region and reads out, in a predetermined order, pixel signals of the plurality of pixels configuring the unit pixel regions. Pixel drive wires, which control readout of the pixels configuring the unit pixel regions adjacent in the vertical direction and having the same readout order, are shared. The present disclosure can be applied to, for example, a CMOS image sensor and the like.
