Abstract:
A signal processing system comprising:means for receiving a low resolution source data line;means for storing said low resolution source data line;means for adjusting a horizontal pixel spacing of said low resolution source data line;means for mapping said low resolution source data line onto one or more nearest neighboring higher resolution destination data lines which have at least a majority area covered by said low resolution source data line;said mapping means including:means for storing a ratio of a number of said higher resolution destination data lines to be displayed to a number of said low resolution source data lines to be received by said receiving means; andmeans for evaluating a relative position of said low resolution source data line in combination with said ratio to determine area coverage of said one or more nearest neighboring higher resolution destination data lines by said low resolution source data line; andmeans for outputting said low resolution source data line from said storing means as each of said one or more nearest neighboring higher resolution data destination lines onto which said low resolution source data line has been mapped.
