An imaging apparatus including: a solid-state imaging device including pixels arranged in rows and columns, the device including: an OB pixel unit including rows of light-shielding pixels among the pixels; and a valid pixel unit including pixels allowing light from the subject to enter among the pixels; an exposure control unit which exposes the second pixel unit; a read line selecting unit which sequentially selects one or more pixel rows of the OB pixel unit, at different timings during exposure of the valid pixel unit, and causes each of pixels of the one or more pixel rows to output a pixel signal; and a dark charge measuring unit which measures the quantity of dark charge due to dark current of the device using current ones of pixel signals, each time pixel signals are output from the OB pixel unit through the selection by the read line selecting unit. |
