摘要

An image pickup apparatus includes a plurality of pixels, a readout circuit configured to read out pixel signals from the pixels for each pixel row, an analog to digital (AD) converter configured to adjust an AD conversion gain depending on an output level of the readout circuit and to provide a signal from the readout circuit with an AD conversion to output image data, and a controller configured to control the AD conversion gain of the AD converter depending on a predetermined condition.
