Title:
Imaging device
Document Type and Number:
Japanese Patent JP6025356
Kind Code:
B2
Abstract:
An embodiment of an image pickup apparatus according to the present invention includes, on a semiconductor substrate, an imaging area having a plurality of pixel columns and a plurality of column circuits each of which is provided for each pixel column or a plurality of pixel columns. Each of the column circuits has a first circuit block and a second circuit block, and the first and second circuit blocks receive a bias voltage via a common wire. The first circuit block includes an amplifier circuit. The second circuit block is configured to be capable of switching between a first mode and a second mode with smaller power consumption than the first mode. A shift period from the second mode to the first mode by the second circuit block is a period excluding a period during which an amplifier circuit in the first circuit block is performing an amplifying operation.
