Abstract: A method and a display driver for compensating the perceptual bias of edge boost when driving a display panel are provided. The method can pre-process an input image to compensate for a perceptual bias of edge boost, e.g., at a contiguous group of color bands in the input image prior to sending the input image in a form of plural frames to a display panel for display. The method includes the steps of partitioning an input image into one or more grayscale regions, segmenting the grayscale regions into a plurality of color bands, detecting a subtle but perceivably significant change of color or luminance between two adjacent color bands, identifying a transition region and performing color dilution on the transition region.

Abstract: A display management processor receives an input image with enhanced dynamic range to be displayed on a target display which has a different dynamic range than a reference display. The input image is first transformed into a perceptually-corrected IPT color space. A non-linear mapping function generates a first tone-mapped signal by mapping the intensity of the input signal from the reference dynamic range into the target dynamic range. The intensity (I) component of the first tone-mapped signal is sharpened to preserve details, and the saturation of the color (P and T) components is adjusted to generate a second tone-mapped output image. A color gamut mapping function is applied to the second tone-mapped output image to generate an image suitable for display onto the target display. The display management pipeline may also be adapted to adjust the intensity and color components of the displayed image according to specially defined display modes.

Abstract: A high dynamic range video processing method performs merging and tone mapping techniques after a Bayer filter mosaic technique is performed and then converts it to red green blue (RGB) at the end as opposed to converting into RGB at the beginning and then performing merging and tone mapping after.

The first mode, full-reset merging, creates an HDR frame once the system has all image frames captured. The second mode, LDR-updating merging, means that any new HDR frame is obtained by an updating of a previous HDR frame with a new LDR frame data.
