High-precision image processing system based on DSP image coding processing

The invention relates to a high-precision image processing system based on DSP image coding processing. The high-precision image processing system comprises an image acquisition mechanism, a signal noise reduction processing module, a signal correction module, a signal conversion module, a signal identification module, a storage module and a display module. Light supplementing operation is conducted through the dimming lamps on the fixed disc, light beams of the dimming lamps are concentrated through the lampshade, light supplementing in different directions is achieved through the dimming lamps at different positions, in the light supplementing process, the motor on the side block works to drive the rotating arm to rotate, and then the convex lens and the concave lens are rotated to the position below the lampshade correspondingly; at the moment, the convex lens concentrates the light of the dimming lamp, and the concave lens disperses the light of the dimming lamp, so that the light intensity adjustment of
