Patent ID: 8086074

Claim:
An image processing system, comprising: an image capturing unit for capturing a first image data, the first image data having a plurality of pixels, each pixel corresponding to one position datum; a first storage unit for storing the first image data; a resolution conversion unit for converting the first image data into a second image data; a second storage unit for storing at least one detection rule; a detection unit for detecting a plurality of position data from the second image data according to the detection rule; a third storage unit for storing the plurality of position data; a direct memory access control unit for accessing the first storage unit and the third storage unit; a first processing unit for generating a mapping table, according to a predefined encryption rule, by accessing the first storage unit and the third storage unit through the direct memory access control unit, the mapping table recording the mapped positions of at least a portion of pixels; a fourth storage unit for storing the mapping table, the direct memory access control unit further accessing the fourth storage unit; a second processing unit for generating a third image data by accessing the first storage unit and the fourth storage unit through the direct memory access control unit; and a fifth storage unit for storing the third image data.
