Image generation method and device for terminal, storage medium and terminal

Abstract

The invention discloses an image generation method and device for a terminal, a storage medium and the terminal, the terminal is provided with a main camera and an auxiliary camera, and the method comprises the following steps: obtaining a first main image shot by the main camera under a first exposure value and a first auxiliary image shot by the auxiliary camera under the first exposure value; if high dynamic processing needs to be carried out, obtaining at least one second main image shot by the main camera under at least one second exposure value; judging whether to perform image fusion processing on the first main image and the at least one second main image, and if so, generating a high dynamic range image; and synthesizing the high dynamic range image and a depth image to generate aresult image, the depth image being calculated and determined by the first main image and the first auxiliary image. Through the scheme of the invention, an image with better quality can be obtainedduring out-of-focus imaging.

Description

technical field [0001] The present invention relates to the technical field of image processing, and in particular to an image generation method and device for a terminal, a storage medium, and a terminal. Background technique [0002] Bokeh refers to imaging outside the focal point, usually a virtual image. The process of out-of-focus imaging is usually to calculate the depth image according to the images captured by the main camera and the secondary camera of the terminal respectively, and then apply the depth image to the image captured by the main camera. However, in some special scenes with large differences in luminance value ranges such as High-Dynamic Range (HDR), dark light, and backlighting, this method of out-of-focus imaging cannot take into account both light and dark details in the scene, that is, It is easy to appear that the area with high brightness value is too bright, or the area with low brightness value is too dark, which will lead to poor quality of ou...

However, in some special scenes with large differences in luminance value ranges such as High-Dynamic Range (HDR), dark light, and backlighting, this method of out-of-focus imaging cannot take into account both light and dark details in the scene, that is, It is easy to appear that the area with high brightness value is too bright, or the area with low brightness value is too dark, resulting in poor quality of out-of-focus imaging, and the resulting image has too few details
