Imaging element and electronic apparatus

An imaging element comprising:

• a first pixel block having a plurality of pixels including color filters of a same first color;
• a second pixel block having a plurality of pixels including color filters of a same second color that is different from the first pixel block, the number of pixels of the second pixel block being different from the number of pixels of the first pixel block;
• and
• an analog-digital conversion unit that converts an analog signal output from each pixel of the first pixel block and the second pixel block into a digital signal,
• wherein the first pixel block and the second pixel block each have a plurality of pixel pairs each including two pixels,
• a plurality of lenses is provided at positions corresponding to the plurality of pixel pairs,
• the first pixel block and the second pixel block each have a pixel-sharing configuration in which a charge-voltage conversion unit that converts a charge obtained in a photoelectric conversion unit into a voltage and succeeding pixel constituent elements are shared among a plurality of pixels,
• the analog-digital conversion unit is a single-slope analog-digital conversion unit that uses, as a signal for reference in analog-digital conversion, a reference signal of a ramp wave given from a reference signal generation unit,
• a plurality of reference signal generation units that generate reference signals of ramp waves having different slopes are provided as the reference signal generation unit,
• the imaging element further comprises
• a signal amount adjustment unit that adjusts output signal amounts output from the pixels of the first pixel block and the second pixel block, and
• the signal amount adjustment unit adjusts the output signal amounts so that an output signal amount concerning the first color output from the first pixel block and an output signal amount concerning the second color output from the second pixel block match on a basis of the reference signals of the ramp waves having the different slopes generated by the plurality of reference signal generation units.
