Abstract
An operation method performed by an image processor is provided, including the following operations: receiving a mixed image including an input image and a first on-screen-display (OSD) pattern; generating a second OSD pattern, different from the first OSD pattern, based on the mixed image. The second OSD pattern encompasses protection regions of the input image, and the protection regions are in close proximity of the first OSD pattern. The method further includes operations of performing image processing to remaining regions, different from the protection regions, of the input image and generating an output image. The output image includes the second OSD pattern and the remaining regions of the input image, being performed by the image processing.
