A solid-state imaging apparatus includes a pixel array in which pixels are arranged in a matrix. Each pixel includes a photoelectric conversion element, a transfer transistor, an amplifier transistor, and a reset transistor. The pixel array an effective pixel part in which light enters the photoelectric conversion element and which is configured to output a video signal, an optical black pixel part in which the photoelectric conversion element is shielded from light and which is configured to output a reference signal, and a dummy pixel part. Of pixels connected to the same signal output line, effective pixels of the effective pixel part are configured such that a first potential is supplied from the reset transistor to a floating diffusion part, and clipping pixels of the dummy pixel part are configured such that a second potential is supplied from the reset transistor to the floating diffusion part.
