Problems solved by technology

However, since the sensor in the camera can only sense light and cannot recognize the bright environment in which it is located, it is impossible for the camera to adapt to different white balances like the human eye, and it is easy to cause some scenes with accurate white balance and some scenes white balance failure

Embodiment Construction

[0020] 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 only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see figure 1 , figure 1 It is a schematic flowchart of an embodiment of the white balance adjustment method of the present invention. Such as figure 1 As shown, the mobile terminal involved in the present invention includes at least a first camera and a second camera, and the shooting directions of the first camera and the second camera are different. For example, the first camera may be a rear camera, the second camera may be a front camera, and the...

Abstract

The present invention discloses a mobile terminal and white balance adjustment method. The white balance adjustment method includes: using the first camera to obtain the first original image, using the second camera to obtain the second original image; the first original image is used to calculate the first white white to obtain the first white whiteBalanced correction gain, use the second original image calculation to obtain a second white balanced liquidity gain; use the judgment weight, the first white balanced school gain, and the gain of the second white balanced school gain calculation to obtain the ultimate white balanced school gain; use the final white balance correction correctionThe gain adjustment of the first original image is adjusted.Through the above methods, the present invention can improve the accuracy of the first camera, that is, the rear camera, the rear camera.

Description

technical field [0001] The invention relates to the field of image technology, in particular to a mobile terminal and a white balance adjustment method. Background technique [0002] White balance is the accuracy indicator describing the mixture of red, green and blue primary colors to form white. Its basic concept is that white can be restored to white under any light source. For the color cast phenomenon that occurs when shooting under a specific light source, it can be adjusted by strengthening the corresponding Complementary color to complement, that is, white balance adjustment. [0003] With the development of electronic technology, more and more smart devices with a camera function are used in people's lives. However, since the sensor in the camera can only sense light and cannot recognize the bright environment in which it is located, it is impossible for the camera to adapt to different white balances like the human eye, and it is easy to cause some scenes with acc...
