Problems solved by technology

[0003] Color screen readers can display graphic content with color components, for example, you can browse comics, web pages, videos and other image content through color screen readers, but color screen readers produce more afterimages than black and white readers. Serious, and the content of the image is more complex than that of the text (such as a reading page), and the randomness of the arrangement is stronger, so the degree of afterimage is further deepened

Abstract

The invention discloses a refreshing method of a color screen reader, the color screen reader and a computer storage medium. The method comprises the following steps: reading a color image to be displayed; extracting a color component of each pixel in the color image to obtain a color extraction image; converting the color extraction image into a gray scale image; carrying out gray scale reduction processing on the gray scale image; and searching a driving waveform according to the gray-scale image after the gray-scale reduction processing, and driving the ink screen by using the driving waveform to realize image refreshing. According to the scheme provided by the invention, the required color component is extracted from the to-be-displayed color image to obtain the color extraction image, the color extraction image is converted into the low-order grayscale image, the driving waveform is searched based on the low-order grayscale image, the driving waveform is utilized to drive the ink screen, and image refreshing is realized, so that the refreshing effect of the color screen reader is improved; the problem that image quality is seriously influenced by ghosting is effectively controlled, the flicker frequency is effectively controlled, the refreshing speed is integrally increased, and the user experience is improved.

Description

technical field [0001] The invention relates to the technical field of image display, in particular to a method for refreshing a color screen reader, a color screen reader and a computer storage medium. Background technique [0002] With the continuous development of science and technology and society, a color screen reader has appeared. The principle is to add a layer of color filter film on the black and white ink screen through printed circuit technology, and the light is irradiated from the outside of the screen to the ink capsule and then reflected. When the screen is reflected, the color effect is achieved through the color filter film. [0003] Color screen readers can display graphic content with color components, for example, you can browse comics, web pages, videos and other image content through color screen readers, but color screen readers produce more afterimages than black and white readers. Seriously, and the content of the image is more complex than that of...
