Abstract
An apparatus includes a photodiode including an anode and a cathode, a switch connected to a node of one of the anode and the cathode and to a power supply line via which a driving voltage is supplied, and functioning to switch a resistance value between the node and the power supply line, and a generation unit configured to generate a pulse signal for controlling switching of the switch. The apparatus is operable in one of two modes including a first mode and a second mode, the second mode being usable in a lower luminance condition than a luminance condition in the first mode. In an exposure period for acquiring one frame of signals, the number of pulse signals in the second mode is smaller than in the first mode.
