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

An image data processing method of an imaging element incorporating a first processor configured to read out image data obtained by imaging a subject at a first frame rate, process the image data, and output the processed image data at a second frame rate, and a memory that stores the image data read out by the first processor, the image data processing method comprising:

• setting the first frame rate to a frame rate higher than the second frame rate;
• and
• by the first processor,
• reading out the image data of a plurality of frames in parallel within an output period of the image data of one frame defined by the second frame rate;
• acquiring a focus driving speed and a rolling shift amount, deciding a combining condition for the image data of the plurality of frames stored in the memory based on the acquired focus driving speed and the rolling shift amount, and performing combining processing on the image data of the plurality of frames in accordance with the decided combining condition;
• and
• outputting the image data after combining obtained by the combining processing.

A non-transitory recording medium that records a program causing a computer to execute an image data process in an imaging element that reads out image data obtained by imaging a subject at a first frame rate, stores the image data which is read out in a memory, processes the image data, and outputs the processed image data at a second frame rate,

• the first frame rate being a frame rate higher than the second frame rate,
• the image data process comprising:
• reading out the image data of a plurality of frames in parallel within an output period of the image data of one frame defined by the second frame rate;
• acquiring a focus driving speed and a rolling shift amount, deciding a combining condition for the image data of the plurality of frames stored in the memory based on the acquired focus driving speed and the rolling shift amount, and performing combining processing on the image data of the plurality of frames in accordance with the decided combining condition;
• and
• outputting the image data after combining obtained by the combining processing.
