METHOD OF IMPROVING THE PERCEPTUAL CONTRAST OF DISPLAYED IMAGES |
摘要 |
<p>A method of processing an image comprising: measuring a set of pixel dependent attributes for a pixelated video frame, each pixel of the frame having a gray level, each gray level associated with a brightness level; and in response to each and every pixel dependent attribute of the set of pixel dependent attributes meeting a corresponding criteria, decreasing the overall brightness of the video frame in accordance with a global brightness signal and increasing the brightness of the gray level of each pixel of the video frame in accordance with a local brightness control signal, the amount a particular gray level brightness is increased being dependent upon the particular gray level and a function of the measured pixel dependent attributes.</p> |
