Imaging element, imaging apparatus, image data processing method, and program for reducing power consumption

An image data processing method of an imaging element in which a memory, an image processing circuit, and an output circuit are incorporated, the image data processing method comprising:

• storing captured image data obtained by imaging a subject at a first frame rate by the memory;
• performing processing on the captured image data by the image processing circuit;
• outputting at least one of the captured image data or processed image data obtained by performing the processing on the captured image data to an outside of the imaging element by the output circuit;
• generating, by the image processing circuit, in accordance with a degree of difference between first captured image data obtained by imaging and second captured image data stored in the memory, compressed image data obtained by compressing the first captured image data by dividing the first captured image data into a plurality of bit ranges;
• and
• outputting the compressed image data generated by the image processing circuit to the outside as the processed image data at a second frame rate by the output circuit.

A non-transitory computer-readable storage medium storing a program for causing a computer to function as

• an image processing circuit and an output circuit included in an imaging element in which a memory, the image processing circuit, and the output circuit are incorporated,
• wherein the memory stores captured image data obtained by imaging a subject at a first frame rate,
• the image processing circuit performs processing on the captured image data,
• the output circuit outputs at least one of the captured image data or processed image data obtained by performing the processing on the captured image data to an outside of the imaging element,
• the image processing circuit generates, in accordance with a degree of difference between first captured image data obtained by imaging and second captured image data stored in the memory, compressed image data obtained by compressing the first captured image data by dividing the first captured image data into a plurality of bit ranges, and
• the output circuit outputs the compressed image data generated by the image processing circuit to the outside as the processed image data at a second frame rate.
