SYSTEMS AND METHODS FOR APPLYING ADAPTIVE GAMMA IN IMAGE PROCESSING FOR HIGH BRIGHTNESS AND HIGH DYNAMIC RANGE DISPLAYS |
摘要 |
<p>Systems and methods of image processing are provided for a display having a light source modulation layer and a display modulation layer. A section of a perceptual curve, such as a DICOM curve, is extracted for each frame of image data, based on a profile of expected luminance on the display modulation layer from light emitted by the light source modulation layer. The section of the perceptual curve may be used to determine a desired-total response curve which maps display modulation layer input control values to corresponding output luminance values. The desired-total response curve and a display modulator-specific response curve may be applied to image data to generate control values for driving the display modulation layer.</p> |
