Problems solved by technology

[0003] Compared with ordinary images, high-dynamic range (High-Dynamic Range, HDR) images can provide more dynamic range and image details; it is based on low-dynamic range (Low-Dynamic Range, LDR) images of different exposure times, using Each exposure time corresponds to the LDR image with the best details to synthesize the final HDR image, which can better reflect the visual effect in the real environment; currently, single-camera mobile phones are used to shoot different exposure values ​​(Exposure Value, EV ) image to finally get an HDR image, if the mobile phone determines that it needs to take a certain number of images under different EV values ​​for HDR image processing, it can only take one image at a time, which reduces the speed of subsequent HDR image processing

Abstract

The invention discloses an image shooting device which comprises an allocation module, an acquisition module and a processing module, wherein the distribution module is used for dividing N unequal EVs (Exposure Values) into a first group of EVs and a second group of EVs, allocating the first group of EVs to a first camera, and allocating the second group of EVs to a second camera; N is an integer greater than or equal to 2; the acquisition module is used for acquiring a first group of images shot by the first camera according to the first group of EVs and a second group of images shot by the second camera according to the second group of EVs; and the processing module is used for carrying out image fusion processing on the first group of images and the second group of images. The invention simultaneously further discloses an image shooting method. Rapid shooting on a plurality of images with different EVs is implemented, an HDR (High-Dynamic Range) effect is achieved, and user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a device and method for taking pictures. Background technique [0002] With the continuous improvement of the resolution of mobile phone cameras and the increasing maturity of camera phone technology, mobile phones have gradually replaced cameras due to their advantages of small size, light weight, and portability, and have become a convenient tool for people to take pictures every day. [0003] Compared with ordinary images, high-dynamic range (High-Dynamic Range, HDR) images can provide more dynamic range and image details; it is based on low-dynamic range (Low-Dynamic Range, LDR) images of different exposure times, using Each exposure time corresponds to the LDR image with the best details to synthesize the final HDR image, which can better reflect the visual effect in the real environment; currently, single-camera mobile phones are used to shoot different exp...
