Abstract :
We present the design of a real time image processing circuit based on an optimized Canny Deriche filter for ramp edge detection. This filter is implemented in a recursive form. A retiming method is used to achieve very high speed filtering. The edge calculation function has been implemented using a CMOS 1 μm process (area 29 mm2). This ASIC is able to process a pixel in less than 30 ns and image sizes from 64×64 to 1024×1024 pixels
