Edge enhancement apparatus to enhance a edge and video accelator of using the same

摘要

The present invention relates to an outline reinforcement apparatus for reinforcing an outline of an image of video data to improve a screen quality and a video accelerator using the same. Because the image is sampled as a rough image, the outline of the image is made smoother than the original outline. The outline of the outline can be made clear by reading the change in the outline of the sampled image and adding the read to the original image. Thus, the outline can be emphasized compared to the sampled image to make the image look more realistic and clear.
