1. A solid-state imaging device comprising:

  • a pixel unit in which pixels that perform photoelectric conversion are arranged in an optical black region and a valid pixel region;

    a readout processing unit that applies, to a readout signal of the pixel unit, readout processing corresponding to a reference signal subjected to clamp processing; and

    a clamp processing unit that clamps, referring to a readout signal level in the optical black region, a reference signal in the valid pixel region with an acquired clamp value, which is a value with which the signal level is reduced to zero, whereinthe clamp processing unit acquires, when information concerning readout is changed, a clamp value predicted from the clamp value before the change and a ratio of charge accumulation times before and after the change, andthe readout processing unit performs first signal readout processing after the change with a reference signal clamped by the predicted clamp value.
