Abstract

The invention provides an electronic front curtain timing control device and method and an image acquisition device, and the method comprises the steps: obtaining a time delay parameter of a timing control signal of an electronic front curtain, generating a plurality of pulses according to the time delay parameter, and outputting the timing control signal according to the plurality of pulses. According to the scheme, non-linear electronic front curtain exposure time sequence control can be stably and accurately simulated based on the time delay parameter of the timing control signal, and the purpose of replacing a mechanical front curtain is achieved.

Description

technical field [0001] The present disclosure relates to the technical field of drive control, in particular, to an electronic front curtain timing control device and method, and an image acquisition device. Background technique [0002] The mechanical shutter has a mechanical structure of the front curtain and the rear curtain. During the movement of the front curtain and the rear curtain, jitter will inevitably be introduced, which will affect the image quality of the camera. Due to the aforementioned drawbacks, electromechanical hybrid shutters were introduced. The electromechanical hybrid shutter adopts an electronic front curtain and a mechanical rear curtain structure. The introduction of the electronic front curtain can fundamentally eliminate the jitter effect caused by the mechanical front curtain. The electronic front curtain needs to simulate the exposure opening sequence of the mechanical front curtain in order to achieve the effect of the mechanical front curt...
