Abstract:
1. A solid state imaging device comprising: an AD conversion section that has one comparison section, which receives a reference signal from a reference signal generator that generates the reference signal whose level gradually changes and which compares the reference signal with an analog signal to be processed, and one counting section, which receives a count clock for AD conversion and performs a count operation on the basis of a comparison result of the comparison section, for each of M signal lines to which the signal to be processed is supplied and that acquires digital data of the signal to be processed on the basis of output data of the counting section; an operation period control section that controls an operation period of the counting section on the basis of the comparison result of the comparison section; and a control section that performs control regarding which of the signals to be processed, which are supplied through the M signal lines, is to be processed and which one of m levels of the signals to be processed is to be processed and also controls the processing order.
