Adjusting method, device and apparatus for character contrast ratio in display page

Abstract

The invention discloses an adjusting method, device and apparatus for character contrast in a display page. Based on a comprehensive processing thought of distinguishing display objects, reducing global color positions and avoiding non-target and secondary drawing, the character contrast ratio in the display page can be adjusted in a targeted manner, specifically, a character object and a non-character object are distinguished in advance, the original information of the non-character object is obtained, the non-character object is excluded out of the gamma value adjustment range, global gray scale processing is adopted in the processing process, the overall calculation amount is reduced while gamma value adjustment is matched, and finally, redrawing the page after the character pixels areadjusted. Particularly, the original information of the non-character object is used for backfilling the non-character object, so that the whole page information displayed to the user is still lossless while the expected character display effect of the user is achieved, and the specific requirements of the user are met on the premise that the use experience is not influenced.

Description

technical field [0001] The present invention relates to the technical field of image processing of electronic equipment, in particular to a method, device and equipment for adjusting the contrast of characters in a display page. Background technique [0002] With the development of science and technology, various electronic products with display functions have been popularized in people's life and work. Users can read and browse information through the screen of the display device, such as a type of e-book mainly for reading needs. product.

[0003] Through actual investigation and analysis, it is found that when users browse and read the content of the page, they have relatively specific requirements for the display effect of the characters (the visual experience presented in front of the user's eyes), that is, the present invention pays attention to the factors that affect the user experience of the above products. One of the key factors, however, there is no reasonable solution to this requirement in the current art

[0004] Although based on conventional ideas and technical means, it is possible to change the visual effect of characters by adjusting the overall display parameters of the page, but the original intention of this method is not to tailor characters, ignoring the targeted use of users demand, so the above adjustment method is not satisfactory, and may even affect the overall display effect of the page
