Patent ID: 7142251

Claim:
A video input processor, comprising: a first buffer to store an input video data, the input video data corresponding to values of a plurality of video components for a video image formatted according to one of several potential video data formats; and a video format converter, coupled to the first buffer to receive the input video data, configured to convert the input video data from its initial video format to a uniform video format and to generate a first video output corresponding to the converted input video data, wherein the uniform video format corresponds to a ratio between different components of the input video data, the video format converter further comprising: a storage element, coupled to the first buffer, configured to receive the input video data from the first buffer, and to select and output a portion of the input video data responsive to a control signal, wherein the storage element has a pre-determined number of outputs; and a logic module, coupled to the storage element, configured to receive the selected portion of the input video data from the predetermined number of outputs of the storage element, and further configured to compare the portion of input video data received from the storage element and to generate an averaged output by averaging the intermediate values of the received portion of input video data.
