METHOD AND APPARATUS FOR ADJUSTING WHITE BALANCE, AND MOBILE TERMINAL
Document Type and Number:
WIPO Patent Application WO/2018/040523
Kind Code:
A1
Abstract:
Disclosed in the present invention are a method and an apparatus for adjusting white balance, and a mobile terminal, the method comprising: dividing an image into different areas according to colour temperature scenes; respectively calculating the white balance of each area; and, on the basis of the calculation results of the white balance of each area, adjusting the white balance of the corresponding areas. When taking a photograph in mixed colour temperature scenes, the mobile terminal using the present method can automatically recognise the colour temperature scenes present in the image, and divide the image into areas on the basis of the colour temperature scenes. After executing a photograph operation, the mobile terminal can automatically calculate the white balance results of each area and adjust the white balance of each area, thereby obtaining a photograph having an ideal white balance effect. In addition, the mobile terminal can also perform a smooth transition of the white balance at the boundaries of each area, so that jumps of the white balance do not occur.
