Abstract

The invention provides a high dynamic range image shooting method and a mobile terminal. The method comprises the following steps: obtaining a first preview image collected by a first camera; determining a foreground image area and a background image area in the first preview image; if a shooting instruction is received, separately obtaining a second preview image collected by the first camera and a third preview image collected by a second camera; performing image synthesis processing on the second preview image and the third preview image to output a high dynamic range image, wherein the second preview image is an exposed image of the foreground image area, and the third preview image is an exposed image of the background image area. According to the high dynamic range image shooting method provided by the embodiment of the invention, the mobile terminal can be used for avoiding the time difference of photos used for synthesizing the HDR image, thereby reducing the occurrence of double images or ghosts and improving the quality of the photos shot 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...
