Abstract

The embodiment of the invention discloses a control circuit and control method of an image sensor. The image sensor generates sensing data. The control circuit comprises a statistical circuit, an automatic exposure circuit and a calculation circuit. The statistical circuit generates brightness statistical data according to the sensing data. The automatic exposure circuit sets the image sensor and outputs automatic exposure data, wherein the automatic exposure data comprises target brightness of the image sensor. The calculation circuit controls an operation mode of the image sensor according to the brightness statistical data and the automatic exposure data. According to the control circuit and the control method of the image sensor provided by the embodiment of the invention, the operation mode of the image sensor can be automatically switched.

Description

technical field [0001] The present application relates to the technical field of image sensors, in particular to a control circuit and a control method of an image sensor. Background technique [0002] Image sensors currently used for security protection can operate in linear mode or high dynamic range imaging (High Dynamic Range Imaging, HDR) mode, and the mode switching is performed manually by the user, or through a photosensitive or soft photosensitive algorithm according to the scene brightness to perform. However, the practicability of manual switching is not high, and the limitation of switching modes purely based on brightness is relatively large, and the scene adaptability is not high. Contents of the invention [0003] In view of the deficiencies of the prior art, an object of the present application is to provide a control circuit and a control method of an image sensor to improve the deficiencies of the prior art. [0004] An embodiment of the present applica...
