Patent ID: 8466995

Claim:
A solid-state imaging device comprising: a pixel section in which a plurality of pixels performing photoelectric conversion are arranged in a matrix shape; and a pixel signal reading section that has an AD conversion section which reads pixel signals through a plurality of pixel units from the pixel section and performs analog digital (AD) conversion, wherein the pixel signal reading section includes a plurality of comparators each of which compares a reference signal, which is a ramp wave, with read analog signal potentials of pixels in a corresponding column, a plurality of counter latches, each of which is disposed to correspond to each one of the plurality of comparators, is configured to count a comparison time of the corresponding comparator, stops the count when an output of the corresponding comparator is inverted, and retains a corresponding count value, and an adjustment section that performs offset adjustment on the reference signal for each row on which the AD conversion is performed, wherein the adjustment section performs clamp processing on the reference signal on the basis of a set value which is set in response to a control signal, and wherein the set value is set such that an amount of change in an output value of each counter latch is within ±0.5 LSB.
