Abstract

The present invention provides a high dynamic range image shooting method and a mobile terminal. The method includes: acquiring a first preview image collected by a first camera; determining a foreground image area and a background image area in the first preview image; instruction, respectively acquire the second preview image collected by the first camera and the third preview image collected by the second camera; perform image synthesis processing on the second preview image and the third preview image, and output a high A dynamic range image; wherein, the second preview image is an image exposed to the foreground image area, and the third preview image is an image exposed to the background image area. According to the high dynamic range image shooting method provided by the embodiment of the present invention, the mobile terminal can avoid the time difference between the photos used to synthesize the HDR image, thereby reducing the occurrence of ghosting or afterimage, and improving the quality of the photos taken by the mobile terminal.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a high dynamic range image shooting method and a mobile terminal. Background technique [0002] With the development of communication technology, mobile terminals such as mobile phones and tablet computers have become indispensable tools in people's daily life. In order to meet the requirements of the camera function of mobile terminals, high-dynamic range (High-Dynamic Range, HDR) image capture technology is gradually applied to mobile terminals, and mobile terminals can capture long-exposure, short-exposure and normal-exposure photos respectively through the camera. , and synthesize multiple captured photos to obtain an HDR image, and the synthesized HDR image has a more balanced exposure effect, thereby improving the quality of photos taken by the mobile terminal. [0003] However, when the mobile terminal adopts the HDR technology to take pictures, since there will be...
