Abstract: An imaging apparatus includes a first imaging element and a second imaging element. The second imaging element includes a storage portion that stores first image data output from the first imaging element, and a processing portion that processes second image data. A second image indicated by the second image data has a higher resolution than a first image indicated by the first image data. The second imaging element outputs the first image data stored in the storage portion to a specific output destination in a case where a specific subject image is not detected, and outputs the second image data or combined image data obtained by combining the first image data with the second image data using the processing portion to the output destination in a case where the specific subject image is detected.

Abstract: An imaging element incorporates a memory and a processor. The memory stores image data obtained by imaging a subject at a first frame rate. The processor is configured to derive a degree of difference between first image data obtained as the image data by performing imaging and second image data that is obtained as the image data earlier than the first image data and stored in the storage portion, and perform processing of deciding at least one of the first image data or the second image data as the output image data in a case where the derived degree of difference is greater than or equal to a threshold value. The processor is configured to output the decided output image data at a second frame rate.
