Abstract

The present invention relates to the technical field of images, and provides a method for adjusting white balance of cameras of a mobile terminal. The mobile terminal is provided with at least one camera and at least one independent color sensor. The method comprises starting the color sensor during or before the camera is started; acquiring RGB data of the color sensor and acquiring a first color temperature of the current environment according to RGB data through calculation; and carrying out white balance adjustment by using the first color temperature. A mobile terminal used for realizing the above method is also provided. Through addition of the color sensors, white balance adjustment is assisted, automatic white balance can be rapidly restrained, accuracy of automatic white balance at a camera start-up initial stage is ensured, color abnormities during start up of the cameras are removed, and user experience is improved.

Description

technical field [0001] The invention relates to the field of image technology, in particular to a method for adjusting the white balance of a camera of a mobile terminal and the mobile terminal thereof. Background technique [0002] At present, the automatic white balance (Auto White Balance, AWB) of the camera is to calculate the color temperature of the current environment according to the acquired image data after starting the image signal processor (Image Signal Processor, ISP) of the camera module, and then according to the color temperature to adjust. [0003] However, it takes a certain amount of time to start the camera ISP, and it takes a certain amount of time to obtain stable image data, and it also takes a certain amount of time to calculate the color temperature based on the image data. As a result, the white balance is equivalent to being in an invalid state in the early stage of the camera startup. , causing the screen observed by the user to appear abnormal,...
