Page processing method and device

Abstract

The disclosure relates to a page processing method and device, and belongs to the field of display technology. The method includes: calculating the brightness average value of pixels in the page, and judging whether the brightness average value exceeds a preset brightness threshold; when it is determined that the brightness average value exceeds the preset brightness threshold value, extracting a target pixel from the page, and the target pixel includes a first target pixel and a second target pixel At least one of the pixels, the first target pixel is a pixel whose luminance difference between any two sub-pixels is less than a preset difference value, the second target pixel includes a background pixel and a text pixel; an inverse color operation is performed on the target pixel. The disclosure calculates the average brightness value of the pixels in the page, and judges whether the average brightness value exceeds the preset brightness threshold. Color operation can reduce the brightness of the page while keeping the contrast of the page unchanged, avoiding the impact of lowering the brightness on the clarity of the page.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a page processing method and device. Background technique [0002] With the development of display technology, terminal devices can display various pages with a certain brightness. However, when the environment becomes dark, the page displayed by the terminal device tends to be glaring. In order to protect the user's eyes, page processing is required to reduce the brightness of the page. [0003] Any page is composed of pixels, each pixel includes sub-pixels of three colors: red sub-pixel, green sub-pixel and blue sub-pixel, each sub-pixel has 256 luminance, the luminance of any pixel can be adjusted by The brightness of the three sub-pixels is obtained through statistics. In order to reduce the brightness of the page, the terminal device will control the amount of light emitted by each pixel in the page to reduce the brightness of the pixels in the page. [0004] Th...

Problems solved by technology

In order to reduce the brightness of the page, the terminal device will control the amount of light emitted by each pixel in the page to reduce the brightness of the pixels in the page

[0004] The contrast of the page is determined by the difference between the brightness of different pixels. When the terminal device reduces the brightness of the pixels in the page, the difference between the brightness of different pixels decreases, resulting in a decrease in the contrast of the page and affecting the clarity of the page.
