Patent ID: 8917231

Claim:
A method, comprising: synchronizing (a) data writing to a set of pixels in a display during a first period within a video frame, and (b) backlight illumination of a region of the display during a second period, the region of the display is spanned by the set of pixels; collecting data indicative of illumination intensity of light to be emitted in a region of a backlight source of the display during the second period; collecting data indicative of pixel content of at least one pixel of the set of pixels; based at least on one or more of the illumination intensity or the pixel content of the at least one pixel, adjusting a gamma characteristic of the set of pixels within the video frame, where the adjusting includes: identifying a plurality of pixels of the display that spans at least a portion of at least two neighboring regions of an imaging area of the display; identifying a subset of two or more pixel lines of the plurality of pixels, the subset spans an interface region that separates a first region and a second region of the at least two neighboring regions; and for at least first and second pixel lines of the subset of pixel lines, updating a gamma characteristic of at least one pixel in response to completion of writing data to a current pixel line, so that a first gamma value for each pixel in the first pixel line is a value based on an offset from a second gamma value for each pixel in the second pixel line.
