Abstract:
A solid-state imaging device is configured such that an effective pixel and a reference pixel are connected to first and second signal lines, respectively. The solid-state imaging device includes a difference signal output unit configured to perform difference processing on a signal output from a first amplifying transistor included in the effective pixel and a signal output from a second amplifying transistor included in the reference pixel. The difference signal output unit is provided separately from the first and second amplifying transistors.
