Abstract

The invention discloses a method and a device for image rim modification. The method disclosed by the invention comprises steps of choosing a center pixel of an image, wherein the center pixel is any pixel representing the rim of the image in the image, obtaining the brightness value of a center pixel and an adjacent pixel adjacent with the center pixel, and performing brightness switching on the adjacent pixel based on predetermined sub-pixel shared mode. According to the application scheme, the brightness switching is performed on the pixels representing the rim of the image before SPR rendering so as to enhance the contrast effect between the image rim and the image background.

Description

technical field [0001] The present disclosure generally relates to image processing technology, and specifically relates to an image edge modification method and an edge modification device. Background technique [0002] Currently, consumers are gradually improving the display quality of portable mobile terminals, and the design and development of high PPI (Pixel per Inch, pixels per inch) display has become a hot spot in the display industry. At this stage, products above 800PPI have appeared, but the subsequent low aperture ratio and extremely high process requirements have made it difficult to improve the yield of high PPI products, so it is also difficult to reduce the cost. [0003] In this context, SPR (SubPixelRendering, sub-pixel rendering) technology emerged as the times require, providing a shortcut for the marketization of high-PPI technology. The so-called SPR technology refers to the low-PPI pixel array arranged in a reasonable pixel order and sub-pixel renderi...
