Composite method and apparatus for adjusting image resolution

摘要

A composite method and apparatus for adjusting an image resolution are provided, which are applied for adjusting a digital image or de-interlace scanning, especially for achieving an edge enhancing effect. The composite method may include: obtaining an original image and a scaling factor for adjustment S; after that, detecting an edge of the original image and generating an edge map for the original image; then, calculating and generating an adjusted image with 2ⁿ newly-added pixels according to the edge map and the scaling factor for adjustment; and finally, with a bilinear algorithm, converting the adjusted image into a final image, which is S times the original one.
