[0087] This embodiment provides a white balance correction control method for a terminal that includes a first image acquisition module and a second image acquisition module, and the field angle of the second image acquisition module is larger than that of the first image acquisition module; In the process of shooting and using the terminal, the first image can be collected by the first image acquisition module; then, if the first image collected by the first image acquisition module does not meet the white balance correction condition, then the first image with a larger field of view can be used The second image acquisition module acquires a second image, and obtains white balance correction parameters based on the acquired second image; since the second image acquisition module with a better field of view is enabled to acquire image information within a larger field of view range, therefore It can enable the terminal to obtain as many effective grayscale statistical points as...

[0119] For ease of understanding, this embodiment will be described below by taking the terminal as an example of an intelligent mobile terminal.

[0120] see Figure 7 As shown, the intelligent mobile terminal 7 in the present embodiment is provided with a first camera (i.e. the first image acquisition module) 71 and a second camera (i.e. the second image acquisition module) 72 on the back, and the first camera 71 is an intelligent mobile terminal 7 is the rear main camera, and the second camera 72 is the rear auxiliary camera of the smart mobile terminal 7 .

[0121] For an example photographing control method of the smart mobile terminal 7, please refer to Figure 8 shown, including:

[0122] S801: The smart mobile terminal 7 detects a shooting instruction, and starts the first camera 71 to collect a first image.

[0123] S802: Determine whether the first image satisfies the white balance correction condition. Here, it is assumed that the white balance correction conditi...

[0138] For ease of understanding, the following still uses an example in which the terminal is an intelligent mobile terminal for description in this embodiment.

[0139] see Figure 11 As shown, the smart mobile terminal 11 in this embodiment is provided with a main front camera (ie, the first image capture module) 111 and an auxiliary front camera (ie, the second image capture module) 112 on the front. For an example photographing control method of the smart mobile terminal 11, please refer to Figure 12 shown, including:

[0140] S1201: The smart mobile terminal 11 detects a front-facing shooting instruction, and starts the main front-facing camera 111 to collect a first image.

[0141] S1202: Determine whether the first image satisfies the white balance correction condition. Here, it is assumed that the white balance correction condition is not satisfied.

[0142] In this example, S1202 determines whether the image type of the first image belongs to the image type in th...

Abstract

The invention discloses a terminal, a white balance correction control method thereof and a computer readable storage medium, and the method comprises the steps: collecting a first image through a first image collection module in the shooting and using process of the terminal; When it is determined that the first image does not meet the white balance correction condition, a second image is collected through a second image collection module with a larger field angle, and a white balance correction parameter is obtained based on the collected second image; The invention further discloses a terminal and a computer readable storage medium. By implementing the above scheme, The second image acquisition module with a better view field angle is started to acquire image information in a larger view field angle range; therefore, the terminal can obtain more effective gray scale statistical points as much as possible; Therefore, the terminal can calculate more accurate white balance correction parameters, the condition of color cast of a shot image caused by white balance correction parameter calculation failure or error due to insufficient number of effective gray scale statistical points is avoided, and the satisfaction degree of user experience is improved.

Description

technical field [0001] The present invention relates to the field of image technology, and more specifically, to a terminal, a white balance correction control method thereof, and a computer-readable storage medium. Background technique [0002] Due to the adaptability of the human eye, white can be accurately judged under different color temperatures, but the camera does not have this adaptability. White balance processing is required. 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] The camera imaging of smart devices such as mobile phones can bring true colors mainly by extracting grayscale statistics from th...
