Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0033] The present invention pays attention to that when superimposed drawing is adopted, if the foreground color and the background color are drawn for each segmented monochrome image, when there is an overlap between the image drawn in the previous time and the image drawn in the next time, the correct result cannot often be obtained , therefore, this method uses the pixel matrix data of the same size when drawing. When the pixel is 1, set the pixel as the foreground color, and if it is 0, it will not be changed....

Abstract

The invention discloses an image rendering method. The method comprises steps of segmenting a multicolor image into a plurality of monochrome images, setting foreground color for each monochrome image, acquiring pixel dot matrix data of the monochrome image, and rendering the corresponding foreground color according to the pixel dot matrix data. The invention also discloses an image rendering system, which comprises a segmenting unit, an image pixel dot matrix data acquisition unit, an initial coordinate setting unit, a foreground color setting unit and a traversal drawing unit. According to the scheme of the invention, simple pixel dot matrix data are adopted, rendering of a complicated image can be realized via simple combination, the memory is saved, the rendering efficiency is improved, and the method can be applied to an embedded system.

Description

technical field [0001] The invention relates to the field of image processing, and relates to an image rendering method and system, in particular to a complex image rendering method and system suitable for embedded systems. Background technique [0002] Image rendering is a technique commonly used in embedded system development. "Research on Image Drawing Method Realized by C Language" (see Journal of China Coal Economics Institute, Issue 02, 1995) provides an image drawing realized by C language. For simple monochromatic images, it is often converted into pixel lattice data, and the foreground color and background color are set separately before drawing, and it is realized by drawing points one by one. This method is easy to program, but it can only draw simple images in monochrome. [0003] For complex multi-color images, for example, if the image has more than two colors, if it needs to be drawn correctly, one way is to represent each pixel with a byte or a word, but th...
