Abstract :
A single chip that can perform three-channel 1×4 serial color matrixing, 3×4 color matrixing, 3×3 (2-D) convolution, and a nine-TAP FIR filter has been designed in a 1-μm gate array. The chip operates at 25 MHz and is useful for color optimization in scanning applications using linear CCD sensors, in electronic imaging applications using area sensors, and in a variety of image processing applications such as edge direction, enhancement, filtering and precompression processing
