Imaging device

An imaging device, comprising:

• a plurality of pixels in any one of a plurality of semiconductor substrates, wherein each of the plurality of pixels is configured to execute photoelectric conversion for a frame of an image;
• a memory in any one of the plurality of semiconductor substrates, wherein the memory is configured to store a plurality of pieces of image data generated based on a result of the photoelectric conversion for the frame;
• a memory control unit in any one of the plurality of semiconductor substrates, wherein
• the memory control unit is configured to execute a read operation based on a piece of internal address information of a plurality of pieces of the internal address information,
• the read operation is executed to read, from the plurality of pieces of the image data stored in the memory, a piece of the image data for the frame, and
• the piece of the image data corresponds to the piece of the internal address information and a partial image of partial images of the frame;
• and
• a bus interface in any one of the plurality of semiconductor substrates, wherein the bus interface is configured to:
• execute communication for address information with an external device;
• supply the memory control unit with the plurality of pieces of the internal address information;
• and
• transmit, to the external device, the read piece of the image data corresponding to the piece of the internal address information.
