Exposure data acquisition method and electronic equipment

Abstract

The invention provides an exposure data acquisition method and electronic equipment. The method comprises the steps: determining a scanning synchronization signal corresponding to a target region on adisplay screen of electronic equipment; determining a real-time screen-off area and movement parameter information of the real-time screen-off area according to the scanning synchronization signal; according to pixels occupied by the real-time screen-off area, movement parameter information and pixels occupied by the target area, determining the covering duration of the target area continuously covered by the real-time screen-off area and the interval duration between the two times of covering; according to the coverage duration and the interval duration, controlling a target photosensitive part in the electronic equipment to perform exposure to obtain exposure data. The target area is an area, corresponding to the target photosensitive part, on the display screen. According to the scheme, a problem that in the prior art, an exposure implementation scheme of a photosensitive device in electronic equipment wastes the effective utilization area of a screen is well solved.

Description

technical field [0001] The present invention relates to the technical field of electronic equipment, in particular to an exposure data acquisition method and electronic equipment. Background technique [0002] In order to increase the screen ratio in current mobile terminals, water drop screens or hole-digging screens are often used, that is, space is reserved for the camera to receive light at the edge of the rectangular screen or the screen area, such as figure 1 shown (when not using the front camera). Because the screen will emit light when taking pictures, in order to reduce the stray light generated by the screen and diffract to the camera nearby, resulting in poor imaging effect, usually set a certain width of black border outside the camera acceptance angle (Fov) to absorb Stray light from the screen, such as figure 2 shown (when using the front camera). [0003] However, when taking a selfie on the front, setting the black border on the screen to absorb stray li...
