A DISPLAY APPARATUS AND A METHOD THEREFOR

摘要

A display apparatus for presenting an image comprises an image receiver (101) for receiving an image to be displayed. An image analyzer (103) performs a local image profile analysis on at least a first region of the image to determine a pixel value spatial variation characteristic. The image analyzer (103) is coupled to a scaling processor (105) which scales at least a second region of the image in response to the pixel value spatial variation characteristic. The scaling processor (105) is coupled to a presentation controller (107) which presents the scaled image. The scaling may specifically be adjusted dependent on a sharpness or spatial frequency characteristics of the image. The invention may allow an improved adaptation of the presentation of one or more images to the specific characteristics of the image(s).
