Abstract:
1. A solid-state imaging device comprising: a pixel circuit including a photoelectric conversion device and an amp device that outputs electric charges, which are photoelectrically converted by the photoelectric conversion device, through electric potential modulation of an output signal line; and a reading section including an AD (analog digital) conversion circuit that compares an output level of the signal line with a reference signal which changes with a regular slope and digitalizes an output signal on the basis of a timing at which a previously-defined relationship is satisfied between the output signal and the reference signal, wherein the reading section has wherein the reading section selects, for each pixel, any one of pieces of digital data, which is obtained by subtracting a result of the third AD conversion from a result of the first AD conversion, and digital data, which is obtained by subtracting a result of the fourth AD conversion from a result of the second AD conversion, and generates imaging data on the basis of the selected digital data.
