Title:
IMAGE PICKUP DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/163219
Kind Code:
A1
Abstract:
Provided is an image pickup device wherein power consumption needed for noise reduction of an analog-digital converter is reduced. A first comparator matches the voltage level of a first pixel signal and that of a reference signal in first auto-zero adjustment timing on the basis of a first auto-zero signal. The first comparator compares the first pixel signal and the reference signal with each other in a predetermined period. A second comparator matches, on the basis of a second auto-zero signal, the voltage level of a second pixel signal and that of the reference signal in second auto-zero adjustment timing that is different from the first auto-zero adjustment timing. The second comparator compares the second pixel signal and the reference signal with each other in a predetermined period.
