Imaging element, imaging apparatus, image data processing method, and program

An image data processing method for an imaging element incorporating a reading circuit that reads out, from a photoelectric conversion element, captured image data obtained by imaging a subject by the photoelectric conversion element, a memory that is capable of storing the captured image data read out from the photoelectric conversion element by the reading circuit, and an output circuit that outputs output image data based on the captured image data stored in the memory to an outside of the imaging element, the image data processing method comprising:

• outputting the output image data to the outside at a first frame rate by the output circuit included in the imaging element;
• reading out the captured image data from the photoelectric conversion element at a second frame rate by the reading circuit;
• reading out the captured image data from the photoelectric conversion element using a first reading method or a second reading method having a smaller read data amount than the first reading method by the reading circuit;
• in a case of the first reading method, setting the first frame rate to a frame rate corresponding to the second frame rate;
• in a case of the second reading method, setting the first frame rate to a frame rate lower than in the case of the first reading method;
• and
• switching between the first reading method and the second reading method in accordance with a detection result of a detection circuit that detects a motion of the subject.
