Abstract:
1. A solid-state imaging device which performs AD conversion for one or more analog pixel signals output from corresponding floating diffusion elements of pixels disposed in a two-dimensional matrix, the solid-state imaging device comprising: reference signal generating means, and comparing means of a first column, at least one pixel signal accumulating means configured to provide a pixel signal supplied from a first pixel via a first column pixel signal line, the reference signal generating means being configured to generate a reference signal ramp waveform, and the comparing means of the first column being configured to output a signal when the comparing means determines that there is a predetermined relationship between the pixel signal and the reference signal; switching means for connecting a pixel signal line of a second pixel from a second column of pixels in order to selectively provide a combined signal of the first and second pixels from corresponding first and second columns of pixels to the comparing means of the first column, and further wherein the pixel signals from the second column may also be compared via a comparing means for the second column of pixels.
