Title:
AUTOMATIC WHITE BALANCE ADJUSTMENT METHOD AND APPARATUS, AND COMPUTER-READABLE STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2021/128667
Kind Code:
A1
Abstract:
The present application relates to artificial intelligence technology. Disclosed is an automatic white balance adjustment method. The method comprises: receiving an analog video set captured by a video recording device, and executing a histogram equalization operation on the analog video set to obtain a video data set; performing toning processing on the video data set to obtain a white balance data set; creating a light brightness relation equation according to the white balance data set, and updating pixels of the white balance data set according to the light brightness relation equation to obtain a white balance change set; performing access processing on a standard white balance change set to obtain a white balance access set; presetting a pixel range, and setting a range threshold value; and if the proportion of pixels of the white balance access set that do not exceed the pixel range does not exceed the range threshold value, controlling the video recording device to normally execute a video recording operation. Further provided are an automatic white balance adjustment apparatus and a computer-readable storage medium. The present application can realize an efficient automatic white balance adjustment function.
