Abstract:
A video processing system for processing video values that represent a plurality of lines of pixel values in a field-based structure, comprising:a host microcontroller;a system memory that stores even and odd fields of video data; anda vertical filter that receives at least a portion of a column of initial pixel values and calculates weighted averages of said initial pixel values to calculate individual fields of pixel values representative of an enlarged image of said initial pixel values, and where said vertical filter increases the number of pixel lines used to represent the initial pixel values;said weighted averages calculated using coefficients that are based on the relative proximity of the lines of pixels representing said enlarged image to the location of the lines representing said initial pixel values, said coefficients selected from the group consisting of 3/8, 5/8, 1/8, and 7/8;wherein said vertical filter performs a 2.times. zoom on said initial pixel values.
