Image encoding method for digital video recorders, involves determining outputted resolution of input image data based on resolution obtained by comparing spatial complexity of data with predetermined threshold

摘要

The method involves calculating a spatial complexity of an input image data based on an average dispersion value for each block of the data. The image resolution is determined by comparing the spatial complexity with a predetermined threshold. An outputted resolution of the input image data is determined based on the resolution. Independent claims are also included for the following: (a) an adaptive image encoding apparatus (b) a computer readable medium having stored computer-executable instructions for encoding image.
