Title: SOLID-STATE IMAGING DEVICE, AND CAMERA SYSTEM USING SAME
Abstract:
This solid-state imaging device is provided with a first AD conversion circuit (41) and a second AD conversion circuit (42) in each row. The first AD conversion circuit uses a first comparator (404) to narrow, by way of a binary search, the range in which the voltage of an analog signal is included, and performs first AD conversion for generating a first digital signal, i.e. a high-order part of a digital signal, on the basis of the result of the binary search. The second AD conversion circuit (42) performs second AD conversion for generating a second digital signal, i.e. the remaining low-order part of the digital signal, by measuring the time until the output of a second comparator (405) for comparing the magnitude relationship between a RAMP signal and the narrowed analog signal inverts.
