Photosensitive cells each includes a photodiode (1), a transfer gate (2),
a floating diffusion layer portion (3), an amplifying transistor (4), and
a reset transistor (5). Drains of the amplifying transistors (4) of the
photosensitive cells are connected to a power supply line (10), and a
pulsed power supply voltage (VddC) is applied to the power supply line
(10). Here, a low-level potential (VddC_L) of the power supply voltage
has a predetermined potential higher than zero potential. Specifically,
by making the low-level potential (VddC_L) higher than channel potentials
obtained when a low level is applied to the reset transistors (5), or
channel potentials obtained when a low level is applied to the transfer
gates (2), or channel potentials of the photodiodes (1), a reproduced
image with low noise is read.
