The technique for generating dot matrix of colored graphics based on Matlab

In order to solve the problem of generating dot matrix of colored graphics in the development of embedded system, a feasible algorithm was designed by using Matlab image processing function and its powerful matrix calculation function, and then the algorithm was optimized aiming at the problems of complicated operation, conversion distortion, data spill, picture mixing and matching with the C grammar, etc. existed in traditional methods. The proposed algorithm is proved with the experimental system which adopts DSP30F6010A as the core processor and LMT057DNAFWU as display. The result shows that the image converted has little distortion and good compatibility. This method can be used to image conversion of most formats and the graphic dot matrix is applicable for the development of colored interface based on the embedded system.
