Abstract

A method and apparatus for improving the quality of images for non-real time sensitive applications are disclosed. A preprocessing unit receives a first frame from a input line. The preprocessing unit calculates a difference value between the first frame and a previously-received-frame. The preprocessing unit sends the first frame to a buffer unit coupled to the preprocessing unit. The preprocessing unit sends the difference value to a statistics unit coupled to the preprocessing unit. Using the calculated difference value, the statistics unit determines whether the first frame contains a scene change. The statistics unit generates a strategy for encoding the first frame based on the criteria of whether the first frame contains a scene change and whether the first frame is used in a still image or a moving image. A video coder-decoder coupled to the statistics unit and the buffer unit receives the first frame and the strategy for encoding the first frame simultaneously. The video coder-decoder operates to encode the first frame using this strategy.
