Image processing apparatus

An image processing apparatus comprising:

• an imaging unit;
• serially connected image processors, wherein a first stage processor included in the image processors is connected to the imaging unit;
• a mode instruction circuitry that provides an instruction to select one of operation modes including a moving image capture mode, wherein in the moving image capture mode, each of image processors other than a final stage processor included in the image processors performs a predetermined image processing on a portion of image data that needs to be processed, and outputs the processed portion of the image data and a remaining portion of the image data to a subsequent image processor without performing the predetermined image processing on the remaining portion of the image data;
• and
• a power supply unit that supplies power to the image processors,
• wherein one of the image processors is set as a power supply master, and
• the image processor that has been set as the power supply master performs control so as to sequentially bring the image processors into the power supply state corresponding to the operation mode indicated by the mode instruction circuitry, wherein the control includes measuring first and second predetermined time periods from receipt of the instruction, transmitting a first activation instruction and a first notification of the selected operation mode to a first of the serially connected image processors when the first predetermined time period elapses, and transmitting a second activation instruction and a second notification of the selected operation mode to a second of the serially connected processors when the second predetermined time period elapses.
