AI Technical Summary

Technical Problem

When existing electronic devices output display images, they cannot effectively utilize all the display performance of the screen, resulting in a decrease in color effect.

Method used

By acquiring the first color data corresponding to the output image signal of the screen and the second color data corresponding to the color gamut of the screen, compensating gain processing is performed, color gamut conversion parameters are determined, and color gamut of the output image signal is converted to fully utilize the display performance of the screen.

Benefits of technology

It effectively improves the color brightness, saturation, etc. of the output display image, increases the color details of the image, makes full use of the entire display performance of the screen, and improves the color effect.

Abstract

A color enhancement method and device, an electronic device, and a storage medium. The method is applied to an electronic device, and the electronic device includes a screen. The method may include: obtaining first color data corresponding to an output image signal of the screen, and second color data corresponding to the color gamut of the screen, the second color data being obtained by performing a color test on the screen; performing compensation gain processing on the first color data to obtain compensated color data; determining a color gamut conversion parameter based on the compensated color data and the second color data, and converting the color gamut of the output image signal based on the color gamut conversion parameter. The implementation of the embodiment of the present application can effectively utilize the display performance of the electronic device screen and improve the color effect of the image output and displayed by the electronic device.
