1. A solid-state imaging device comprising:

  • a first substrate including;

    a pixel array unit including a plurality of pixels, anda plurality of vias on a periphery of the first substrate; and

    a second substrate including;

    signal processing circuitry including an AD converter configured to digitize an analog pixel signal read from respective ones of the plurality of pixels through corresponding ones of the plurality of vias, the signal processing circuitry configured to transfer digitized pixel data at a first speed higher than a frame rate;

    a memory configured to store the pixel data transferred from the signal processing circuitry;

    data processing circuitry configured to read pixel data at a second speed lower than the first speed from the memory; and

    control circuitry configured to, when the pixel data is read from the memory unit, stop operation of a current source connected with the signal line and operation of at least the AD converter of the signal processing circuitry.
