Abstract:
A video processing system for decimating a video input image including multiple lines of pixels, comprising:a microcontroller; a memory device coupled to said microcontroller and used to store the video input image; and a decimation device coupled to said memory device for receiving the video input image from said memory device, said decimation device reducing the size of the input image to produce a decimated image by averaging together at least two lines of pixels from the input image for approximately every line of pixels in the decimated image, wherein said input image is represented with an odd field and an even field and the decimation device averages lines of pixels from each field independently, wherein said decimation device calculates a weighted average of at least four pixels from four lines of pixels in the input image to produce a pixel in a line of pixels in the decimated image.
