<P>PROBLEM TO BE SOLVED: To provide a solid-state imaging device capable of adding pixel signals without causing deterioration of the image quality of an imaging result. Ž<P>SOLUTION: The solid-state imaging device which includes a plurality of unit pixels 11 arranged in a matrix pattern, and adds signals from the unit pixels 11, includes: column signal lines 22-1 to 22-m which transmit the signals from the unit pixels 11 in a column direction; and ADCs 23-1 to 23-m which perform analog-digital conversion on the signals transmitted through the column signal lines 22-1 to 22-m, and add the signals obtained by the analog-digital conversion to output the added signal. The ADCs 23-1 to 23-m determine whether or not the signal of one unit pixel 11 is a defective signal exceeding a predetermined voltage range: when determined as not a defective signal, holds, as a signal to be added, a signal obtained through the analog-digital conversion of the signal determined as not a defective signal; and when determined as a defective signal, sets, as a signal to be added, a signal different from a signal obtained through the analog-digital conversion of the defective signal.
