An imaging device includes an effective pixel region outputting an effective pixel signal, a first shielded pixel region outputting a shielded pixel signal before the effective pixel signal is output, and a second shielded pixel region outputting a shielded pixel signal after the effective pixel signal has been output. In the device, in a steady state, frame clamping is performed using a clamping reference value generated from the pixel signals of the second shielded pixel region. A frame in a transition state in which the optical black signal level of the imaging device changes is subjected to frame clamping using a clamping reference value generated from the pixel signals of the first shielded pixel region. |
