Abstract:
1. A solid-state imaging device comprising: an analog-digital converter unit in column parallel arrangement, the analog-digital converter unit having a plurality of pixels arranged to convert an incident light quantity to an electric signal, in which an analog signal obtained from the pixel is converted into a digital signal, wherein the analog-digital converter unit is configured of: a comparator operable to compare a value of a column signal line from which an analog signal obtained by the pixel is outputted with a value of a reference line, and a counter operable to measure a time period by the time when comparison done by the comparator is finished and to store the comparison result, wherein the solid-state imaging device further includes: means for controlling an output of the comparator operable to control the output of the comparator depending on the output of the comparator.
