Adaptive image upscaling method and apparatus

摘要

A method for upscaling image data is provided. The method initiates with identifying a gradient value associated with a pixel location of the image data. Then, it is determined whether a direction associated with the pixel location is either a horizontal direction or a vertical direction. Next, a weighted interpolation scheme is applied to the pixel location when the direction is either a horizontal direction or a vertical direction. A method for applying an interpolation scheme where inter-frame redundancies are exploited is included. A computer readable media, a system for processing block based image data and an integrated circuit for scaling image data are also provided.
