发明名称 Method and system in a data processing system for improved video image resolution when enlarging a video sequence
摘要 A method and system in a data processing system are disclosed for improving video sequence image resolution when creating an enlarged final image from an initial image included within the video sequence. An enlargement factor is determined for creating a final image having a final image size from an initial image having an initial image size, where the enlargement factor is the quotient of the final image size divided by the initial image size. An intermediate factor is established to optimize the image resolution and minimizing the hardware required to produce the image. In response to the enlargement factor being less than the intermediate factor, the final image is created from the initial image utilizing the enlargement factor and bilinear interpolation. In response to the enlargement factor being greater than the intermediate factor, an intermediate image is created. The intermediate image has an intermediate size which is greater than the initial image size and less than the final image size. The intermediate image is created utilizing the initial image, the intermediate factor and bilinear interpolation. Thereafter, the final image is created utilizing the intermediate image, the enlargement factor, the intermediate factor, and nearest neighbor interpolation.
