Embodiment Construction

[0035] The terms used in the embodiments of the present application are only used to explain specific embodiments of the present application, and are not intended to limit the present application.

[0036] In an image fusion scheme provided by the existing related technology, the original (RAW) images collected by the color camera and the black and white camera are respectively converted into a color YUV image and a black and white YUV image, and then the color YUV image and the black and white YUV image are combined Fusion, this image fusion scheme loses more image details, resulting in poor color reproduction of the final image. In addition, during the preview, the imaging effect of the high dynamic scene is quite different from the preview effect, and the user experience is poor. Especially when shooting portraits in backlit scenes, since the background is brighter and the front portrait part is darker, after using the existing high dynamic range image (high dynamic range, ...

Abstract

The embodiment of the invention provides an image processing method and device of a terminal and terminal equipment. The terminal comprises a black-and-white camera and a color camera, and the method comprises: after a photographing function of the terminal is operated, in the preview process, collecting a color RAW image through the color camera, and collecting a black-and-white RAW image through the black-and-white camera; obtaining a shooting instruction, controlling a color camera to shoot a current shooting scene, and obtaining a color RAW image of the shooting scene; performing RAW domain processing on the color RAW image to obtain a processed color RAW image; processing the processed color RAW image to obtain a color YUV image; processing the black and white RAW image collected in the preview process through a second Bayer domain processing algorithm link to obtain a black and white YUV image; fusing the color YUV image and the black and white YUV image to obtain the target color image, so that more image details are reserved, and the color rendition degree of the target color image is improved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of smart terminals, and in particular, to a terminal image processing method, device, and terminal equipment. Background technique [0002] Taking pictures is now a common function in mobile phones. With the popularization of smart phones, the application of cameras has become more and more extensive, and the camera function has become more and more excellent. Excellent camera performance has become a major selling point of smartphones. Technological innovations around the camera function are emerging in an endless stream, and the aperture and sensor size are getting larger and larger. These technology and hardware upgrades have a significant impact on smartphone photography, both in terms of photo quality and overall quality. The camera experience has been greatly improved. While pursuing the quality of photos, the thinning and lightening of smartphone bodies is also a major tr...
