Embodiment Construction

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0019] The terms "first" and "second" in the description and claims of the embodiments of the present invention are used to distinguish different objects, rather than to describe a specific sequence of objects. For example, the first luminance value and the second luminance value are used to distinguish different luminance values, rather than describing a specific order of luminance values. In the description of the embodiments of the present invention...

Abstract

The embodiment of the present invention discloses a high dynamic range image preview method and a terminal device, which relate to the field of communication technology and can solve the problem in the prior art that the HDR composite effect can only be seen when the final captured image is displayed after the photographing is completed. The specific solution is: during the shooting preview process, obtain the initial preview image output by the image sensor; obtain N target exposure gains; control each image processor in the N image processors according to one of the N target exposure gains; Exposure gain, adjust the exposure gain of the initial preview image, generate N-frame intermediate preview images; perform image processing on N-frame intermediate preview images, generate high dynamic range images, and output to the shooting preview interface; wherein, the initial preview output from the image sensor The images are transmitted to each image processor respectively, and N target exposure gains are used to adjust the exposure gains of the initial preview image, where N is an integer greater than 2.

Description

technical field [0001] Embodiments of the present invention relate to the field of communication technologies, and in particular, to a high dynamic range image preview method and a terminal device. Background technique [0002] Currently, a user may use a high-dynamic range (High-Dynamic Range, HDR) mode of a camera of a terminal device to take pictures. Specifically, after the user turns on the HDR mode of the camera of the terminal device and clicks the camera button, the terminal device can be triggered to use the preset three exposure gains (such as 0, +2, and -2) to capture images corresponding to three different exposure gains. images, and perform processing such as synthesis and compression on the three collected images to obtain a photo with HDR effect, and then display the photo with HDR effect on the interface of the terminal device. [0003] It can be seen that in the prior art, the user can see the HDR composition effect only when the final captured image is dis...
