AI Technical Summary

Technical Problem

Existing white balance algorithms perform poorly in extreme lighting conditions and have slow processing speeds, making it difficult to meet the high-efficiency and accuracy requirements of artificial intelligence applications.

Method used

By acquiring the average brightness value of the captured image, the predicted color cast coefficient is determined, and the image is adjusted according to the coefficient to generate a white balance image. The lighting conditions are optimized using an RGB camera and a supplementary light source, and the preset image elements are determined by combining artificial intelligence recognition technology.

Benefits of technology

It improves the efficiency and accuracy of white balance processing, enabling the generation of more natural image colors in extreme lighting conditions, and supports the implementation of artificial intelligence applications such as facial recognition and palm print verification.

Abstract

An image processing method, executed by an electronic device. The method comprises: acquiring a captured image (S21); when the captured image comprises a preset image element, determining an average brightness value of the captured image on the basis of a channel value of each color channel of each pixel point of the captured image (S22); determining a predicted color cast coefficient of the captured image on the basis of the average brightness value of the captured image, the predicted color cast coefficient of the captured image being used for representing the predicted color cast degree of the captured image relative to a reference image (S23); and adjusting the captured image on the basis of the predicted color cast coefficient of the captured image, so as to generate a white balance image (S24).
