Solid-state imaging apparatus and imaging apparatus

An imaging apparatus comprising:

• a solid-state imaging apparatus;
• an optical system that forms an image of incident light on a light receiving surface of the solid-state imaging apparatus;
• and
• a recording unit that stores image data acquired by the solid-state imaging apparatus,
• the solid-state imaging apparatus including
• a pixel array unit including a plurality of pixel blocks arrayed in a matrix, and
• a drive circuit that generates a pixel signal in a first pixel block in which firing of an address event has been detected among the plurality of pixel blocks,
• each of the plurality of pixel blocks including
• a first photoelectric conversion element that generates an electric charge according to an amount of incident light,
• a detection unit that detects the firing of the address event based on the electric charge generated in the first photoelectric conversion element,
• a second photoelectric conversion element that generates an electric charge according to an amount of incident light, and
• a pixel circuit that generates a pixel signal based on the electric charge generated in the second photoelectric conversion element.
