Abstract
A solid-state imaging device with a variable (continuous) electronic shutter function comprises an imaging area where unit cells with photodiodes acting as pixels are arranged two-dimensionally, read lines for driving the read transistors in each pixel row, vertical selection lines for driving the vertical selection transistors in each pixel row, a vertical driving circuit for selectively driving vertical selection lines, vertical signal lines for outputting the signal from each unit cell in the pixel rows driven sequentially, and a row selection circuit for controlling the vertical driving circuit in such a manner that the vertical driving circuit drives the read transistors in each pixel row with the desired signal storage timing and signal read timing twice in that order and thereby drives the vertical selection transistors in the pixel row in synchronization with the signal read timing.
