Abstract

Embodiments of the present invention provide a white balance adjustment method, device, and mobile terminal, wherein the method includes: photographing a reference object to obtain real-time pixel data; according to the real-time pixel data and preset reference pixel data, Determine white balance parameters; perform white balance adjustment based on the white balance parameters and current scene brightness. The embodiment of the present invention performs white balance adjustment according to real-time pixel data, preset reference pixel data, and current scene brightness, and can accurately realize color restoration of the current scene.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of photographing, and in particular, to a method, device and mobile terminal for adjusting white balance. Background technique [0002] With the development of information technology, camera applications on mobile terminals are becoming more and more extensive, and users have higher and higher requirements for image quality after taking pictures. The quality of camera imaging depends on the size of the photosensitive element, the design of the lens and aperture, etc. However, due to the limitation of the size of the mobile terminal, the design and quality of optical components such as photosensitive elements and lenses are limited. Therefore, when designing an ISP (Image Signal Processor, image processor) of a mobile terminal, how to correct the exposure, white balance, etc. for the raw image (raw image) obtained by the photosensitive element is an important research direction.
