Abstract: A solid-state imaging apparatus includes a pixel array, a column processor, and a test signal generating circuit that generates a first digital signal for testing purposes. The test signal generating circuit generates the first digital signal within one horizontal scanning period. The column processor converts a first analog signal, that is converted from the first digital signal, to a second digital signal within the one horizontal scanning period.
