Embodiment Construction

[0064] In order to make the purpose, technical solutions and advantages of the present application, the present application will be further described in detail below with reference to the accompanying drawings.

[0065] In the related art, the mobile terminal during the high number of gray levels in a grayscale image (e.g., 256-level image), a lower number of gray levels is converted to a grayscale image (e.g., grayscale image 16) may include: for each pixel 256 in the gray scale image, the gray value of the mobile terminal can be divided by 16 pixels and the gradation value obtained after rounding updated. Thereafter, the mobile terminal may be based on the gray values ​​of the pixels of the grayscale images 16 updates the display on its screen electronic ink.

[0066] However, if 256 grayscale image, the gray value of the pixel similar to the partial region, will result in the grayscale image is converted into 16, the same gray value pixels of the partial region. Further, leadin...

Abstract

The invention discloses a mobile terminal and an image display method thereof, and relates to the technical field of image processing. According to the mobile terminal, the error of each pixel point in the gray level image of the first gray level number can be transmitted to the pixel points in the neighborhood of the pixel point, so that the error of the adjacent pixel points becomes smaller, the change of the gray values of the adjacent pixel points is smoother, and the displayed image is more natural. And after each pixel in the gray level image is traversed, the mobile terminal can process the traversed gray level image by adopting a contrast enhancement algorithm, so that the contrast of the image is enhanced, and the display effect of the image is effectively improved.

Description

Technical field [0001] The present application relates to the field of image processing, and in particular, to a mobile terminal and an image display method. Background technique [0002] The mobile terminal can convert the gradation level higher grayscale image to a grayscale image of a low gray scale, and display a grayscale image of the gray scale on the electronic ink screen of the mobile terminal. [0003] However, the display effect of the gray scale image is poor in the electronic ink screen. Inventive content [0004] The present application provides a mobile terminal and its image display method, which can solve the problem of the display effect of grayscale images in the electronic ink screen in the electronic ink screen. The technical solution is as follows: [0005] In one aspect, a mobile terminal is provided, the mobile terminal including a processor and an electronic ink screen; the processor for: [0006] The pixel point in the grayscale image of the first gray s...
