Abstract:
1. A solid-state imaging device which performs AD conversion for an analog pixel signal output from pixels disposed in a two-dimensional matrix, the solid-state imaging device comprising: AD conversion means including a plurality of pixel signal accumulating means, reference signal generating means, and comparing means, the pixel signal accumulating means being configured to provide the pixel signal supplied from a first pixel via a pixel signal line, the reference signal generating means being configured to generate a reference signal ramp waveform, and the comparing means being configured to output a signal based on a comparison between the pixel signal and the reference signal: first switching means for disconnecting a parallel connection of second pixel signal accumulating means other than first pixel signal accumulating means which is one of the plurality of pixel signal accumulating means; and second switching means for connecting the second pixel signal accumulating means to a pixel signal line of a second pixel adjacent to the first pixel in a row direction, when parallel connection of the second pixel signal accumulating means is disconnected by the first switching means.
