Abstract

The present application is applicable to the field of image proces technology, and provices a method for generating a high dynamic range image, a mobile terminal and a computer readable storage medium. The method comprises: obtaining a preview picture collected by a camera of the mobile terminal, and identifying foreground objects in the preview screen, based on the foreground objective, selectinga preset number of cameras from a plurality of cameras of the mobile terminal as a target camera, and determining the exposure time corresponding to each target camera, controlling the target camerato acquire images based on the corresponding exposure time, obtaining the image corresponding to each exposure time, and synthesizing the image corresponding to each exposure time to obtain a high dynamic range image. The application can reduce the shooting time of the high dynamic range image and solve the problem of blurring the outline of a local object.

Description

technical field

[0001] The present application belongs to the technical field of image processing, and in particular relates to a method for generating a high dynamic range image, a mobile terminal and a computer-readable storage medium. Background technique

[0002] High-Dynamic Range images (High-Dynamic Range, referred to as HDR), compared with ordinary images, can provide more dynamic range and image details, according to different exposure time LDR (Low-Dynamic Range) Time corresponds to the LDR image with the best details to synthesize the final HDR image, which can better reflect the visual effect of people in the real environment.

[0003] However, when collecting high dynamic range images at present, because it is necessary to obtain images corresponding to multiple exposure times, the total time of the shooting process of high dynamic range images is too long; The acquisition time is long, and the outline of local objects often appears blurred in the synthesized i...
