Abstract:
A method for producing a scaled and filtered, multi-dimensional digital image from an incoming video data stream, wherein the video data is received in a sequence according to a schedule of portions characterized by one of the dimensions of the sequence, comprising the steps of:for each sequence of elements of the video data stream within a first video field of at least a two-field video frame, processing the video data within a first field time byreceiving the sequence of elements of the video data stream in a first dimension; andfiltering the sequence of elements of the video data stream in the first dimension using a programmable scaling filter to provide a first set of scaled data having a first scaled dimension and having at least a second dimension; andduring a subsequent field time of the video data and for each sequence of the first set of scaled data in a second dimension, filtering the first set of scaled data using the programmable scaling filter to provide a set of two-dimensionally scaled data having at least two dimensions.
