Claim 23:
24. An operation method of an imaging element that includes a focus related pixel, which is a pixel that can acquire data related to a focus state of a subject, a reading circuit that reads out pixel data obtained by imaging the subject at a first frame rate, a memory that stores the pixel data read out by the reading circuit, and an output circuit that outputs image data based on the pixel data stored in the memory at a second frame rate, the imaging element incorporating the reading circuit, the memory, and the output circuit,
wherein the first frame rate is a higher frame rate than the second frame rate, and
wherein the pixel data includes focus related pixel data and non-focus related pixel data different from the focus related pixel data,
the operation method comprising, by the reading circuit, reading out the pixel data of each of a plurality of frames in parallel within an output period defined by the second frame rate as a period in which the image data of one frame is output, and performing reading of the non-focus related pixel data and a plurality of readings of the focus related pixel data within the output period.
