Problems solved by technology

Using halftone conversion can retain a relatively complete grayscale transition, but often due to ink smearing, the transition effect cannot be shown when it sticks together, making the entire printing effect black as a whole

Abstract

The embodiment of the invention provides a printed picture enhancement processing method, device and equipment and a storage medium, and relates to the technical field of printers. The method comprises the following steps: obtaining a primary color of a to-be-processed picture; acquiring RGB data of the to-be-processed picture, comparing the RGB data with the primary color based on a preset discrimination method, and acquiring a result color according to a comparison result so as to remove an uneven background in the to-be-processed picture; and obtaining a color mean value of a to-be-processed picture according to the result color, obtaining an enhanced color based on the color mean value, and performing contrast enhancement on the to-be-processed picture according to the enhanced color to obtain a to-be-printed picture. The non-uniform background in the original to-be-processed picture is removed, the gray scale is reduced, the contrast ratio is enhanced, and the printed picture is clearer.

Description

technical field [0001] The present invention relates to the technical field of picture printing processing, in particular, to a printing picture enhancement processing method, device, equipment and storage medium. Background technique [0002] Ribbon printing technology is a technology that transfers binary dot matrix data by using the print head to heat the ribbon. When this technology prints documents on non-smooth media (such as ordinary A4 paper), the ink is easy to smudge. As a result, images with rich gray scales are not printed clearly and the display effect is not good. Therefore, it is mostly used for printing documents with black characters on a white background and strong contrast. [0003] Dot-matrix printers need to convert pictures into black and white binary dot-matrix data for output when printing. There are usually two conversion methods: [0004] (1) The image is directly thresholded in black and white, and the image above the threshold is converted into w...
