Abstract
A control circuit and a control method of an image sensor are provided. The image sensor generates a sensed data. The control circuit includes a statistical circuit, an auto exposure (AE) circuit, and a calculation circuit. The statistical circuit generates a luminance statistical data according to the sensed data. The AE circuit sets the image sensor and outputs an AE data which includes a target luminance of the image sensor. The calculation circuit controls an operation mode of the image sensor according to the luminance statistical data and the AE data.
