1. An imaging element comprising:
an imaging unit including a unit pixel that outputs a pixel signal corresponding to received light; and
at least one processor configured to
generate, on a basis of the pixel signal, a processing pixel signal corresponding to each of a plurality of luminance regions having continuous luminance,
generate a split pixel signal, which is acquired by a split of the pixel signal according to each of the plurality of luminance regions, according to each of the plurality of luminance regions,
generate split pixel data by splitting pixel data, which is based on the pixel signal, at one or more of bit positions for every predetermined number of bits from a most significant bit to a least significant bit, and
add a dummy bit to the split pixel data in a case where a number of bits of the split pixel data corresponding to a luminance region including the least significant bit among the plurality of luminance regions is smaller than the predetermined number of bits.
