A method and electronic device for obtaining exposure data

Abstract

The present invention provides an exposure data acquisition method and an electronic device, wherein the exposure data acquisition method includes: determining a scanning synchronization signal corresponding to a target area on a display screen of the electronic device; determining a real-time off-screen area and Mobile parameter information of the real-time off-screen area; according to the pixels occupied by the real-time off-screen area, the moving parameter information and the pixels occupied by the target area, determine the coverage duration of the real-time off-screen area to continuously cover the target area and the interval between two coverages Duration; according to the coverage duration and the interval duration, control the exposure of the target photosensitive component in the electronic device to obtain exposure data; wherein, the target area is the area corresponding to the target photosensitive component on the display screen. This solution well solves the problem of wasting the effective use area of ​​the screen in the prior art in the exposure implementation scheme of the photosensitive device in the electronic equipment.

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...
