Problems solved by technology

In the existing camera technology, the higher the frame rate, the higher the processing capability requirements of the graphics card. If the frame rate is increased, the image brightness will be lower or the noise will be larger, which will affect the image quality; if the frame rate is lower, Then the white balance adjustment speed is slower, and the time delay for the terminal to display the white balance adjusted image on the monitor is longer

Embodiment Construction

[0025] 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 some of the embodiments of the present invention, but not all of them. 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.

[0026] The embodiment of the present invention discloses a white balance adjustment method. When the terminal judges that the frame rate of the first camera is the maximum frame rate, the terminal obtains the first image through the first camera, and analyzes the first image to obtain the white balance of the first image. Gain, adjust the white balance of the second image obtained through the second camera according to the white balance gain, and d...

Abstract

An embodiment of the invention discloses a white balance adjusting method, device and terminal. The white balance adjusting method comprises obtaining a frame rate of a first camera; judging whether the frame rate is a maximum frame rate or not and obtaining a first image through the first camera if yes; analyzing the first image to obtain white balance gain of the first image; adjusting white balance on a second image through a second camera through the white balance gain; displaying the second image after white balance adjusting. The white balance adjusting method can improve the white balance adjusting speed and reduce the display delay of the image after white balance adjustment under the condition that the image quality is not influenced.

Description

technical field [0001] The present invention relates to the field of electronic technology, in particular to a white balance adjustment method, device and terminal. Background technique [0002] In camera technology, when the camera is started or the light environment changes, it is usually accompanied by a white balance adjustment process. Among them, white balance is used to describe the accuracy with which the red, green and blue primary colors in the display are mixed to generate white. The white balance adjustment speed is usually related to the frame rate. If the frame rate is higher, the white balance adjustment speed is faster, and the time for the terminal to display the white balance adjusted image on the display is shorter. The frame rate is used to measure the transmission rate per unit time. The number of frames of the image. In the existing camera technology, the higher the frame rate, the higher the processing capability requirements of the graphics card. If...
