Abstract
A solid-state imaging device configured to suppress fixed pattern noise having column correlation and/or lateral correlation from being generated in images is disclosed. In one example, a solid-state imaging device includes unit pixels arranged in row and column directions, vertical signal lines respectively connected to at least one of the unit pixels arranged in the column direction, first converters connected to the respective vertical signal lines and configured to convert an analog pixel signal into a digital pixel signal in reading each unit pixel arranged in the row direction, an initialization voltage generator that outputs an initialization voltage for initializing the unit pixels or input nodes of the first converters, and an initialization voltage line that connects the initialization voltage generator and the first converters. The initialization voltage generator changes the initialization voltage that is output for each row and/or column to be processed by the first converters.
