Abstract: A depth map is generated from at least a first and a second image. Generally, a plurality of reference pixels are selected in the first image and associated with respective pixels in the second image. Next, the disparity between each reference pixel and the respective pixel in said second image is determined, and for each reference pixel a depth value as a function of the respective disparity. In particular, each reference pixel is associated with a respective pixel in the second image via a matching and a filtering operation. The matching operation selects for each reference pixel a plurality of candidate pixels in the second image and associates with each candidate pixel a respective cost function value and a respective disparity value.

Abstract: A backlight for a display comprises a plurality of independently controllable groups of light emitters. The brightness levels of the groups of light emitters are controllable by pulse width modulation (PWM) signals generated by PWM driving circuits. The phases of PWM signals to different groups of light emitters are configured to be offset by different amounts, so as to stagger the start times of light emitters of different groups. Such phase-shifting of PWM signals may result in total power consumption that ramps up more gradually, is distributed more evenly over time, and is held to a lower maximum value than if the same PWM signals were not phase-shifted. The duration of a first PWM cycle of PWM signals for an image may also be made longer than subsequent PWM cycles for the image so as to extend the initial power ramp-up time.
