Embodiment Construction

[0060] Embodiments of the present application are described in detail below, examples of which are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary, and are intended to explain the present application, and should not be construed as limiting the present application.

[0061] The various embodiments of the present application mainly aim at the problems of long shooting time and poor effect of the existing image shooting methods, and propose a method of using two cameras, one camera obtains a normal image, and the other camera obtains a different exposure. image, and then process the two images to obtain an image shooting method of an HDR image.

[0062] The image capturing method, device, and terminal device according to the embodiments of the present application are described below with r...

Abstract

The invention provides an image photographing method and device and a terminal device. The method is applied to the terminal device. The terminal device is equipped with a master photographing module and a secondary photographing module. The method comprises the steps of controlling n adjacent pixels corresponding to the same light filter unit in a secondary image sensor to be located in different exposures according to a preset strategy; obtaining a first image and a second image of a photographed object through a master photographing module and the secondary photographing module; splitting the second image, thereby obtaining a third image, wherein the third image and the first image have the same number of pixels; and synthesizing the third image and the first image, thereby obtaining a high-dynamic range image of the photographed object. The two photographing modules are employed; one is used for carrying out normal photographing; the other one is used for obtaining the image with different exposures; then the two images are synthesized to obtain the HDR (High-Dynamic Range) image; the photographing time of the HDR image is shortened; the image photographing effect is improved; and the user experience is improved.

Description

technical field [0001] The present application relates to the field of electronic technology, and in particular to an image capturing method, device and terminal equipment. Background technique [0002] With the development of electronic products and image processing technology, people have higher and higher requirements for image shooting effects. High-Dynamic Range (HDR) images have attracted widespread attention due to their advantages of rich layers, strong picture realism, large dynamic range of images, and better reproduction of light and shadow effects in real scenes. [0003] In the prior art, usually by controlling the exposure, multiple images with different exposures are taken, and then image fusion technology is used to synthesize these images to obtain an HDR image. [0004] However, in the above-mentioned image shooting method, the exposure time of each image is fixed, and the shooting effect is not good, and since multiple images with different exposures need...
