Abstract

The embodiment of the invention provides a global shutter processing method and device. The global shutter processing method provided by the invention comprises the following steps: controlling a global shutter sensor to open and close a shutter according to exposure time length; controlling a light source to light within a preset time period to enable the time period in which the shutter is opened by the global shutter sensor to coincide with the time period in which the light source is lighted, wherein the start time of the preset time period is a preset time before the shutter is opened by the global shutter sensor and the preset time period is larger than the preset exposure time length of the global shutter sensor. The embodiment of the invention is used for solving the problem of high power consumption caused by configuration of the global shutter in a terminal device.

Description

technical field [0001] Embodiments of the present invention relate to power control technologies, and in particular, to a global shutter processing method and device. Background technique [0002] The global shutter enables all pixels to be exposed at the same time, and can obtain clear images. It is mostly used in SLR cameras, enterprise monitoring and other scenarios. When taking pictures of moving objects, enough photosensitive information can be obtained per unit area, so it is relatively easy to obtain clear imaging. [0003] At present, there is no light-weight camera supporting global shutter suitable for mobile phones. The main reason is that the current global shutter requires a strong enough active light source and consumes high power. [0004] It is very important to obtain clear imaging of high-speed moving objects through sensors, such as high-precision gesture recognition. Only by obtaining clear imaging can the meaning of gestures be accurately recognized. ...
