Abstract
The present invention is to provide an image signal detection circuit, a control method, and a motion detection method. The image signal detection circuit comprises at least one acquisition module, the acquisition module comprises at least one acquisition sub-module, the acquisition sub-module comprises a capacitor to acquire the difference between a pair of two consecutive frames of pixel signals by taking a reference voltage as a reference. The image signal detection circuit and a motion detection circuit are structurally simple and easy to implement. It can realize motion detection at increased difference detection speed without analog-to-digital conversion.
