A method and apparatus for facial recognition by a computing device using an adaptive search window and regional similarity distribution analysis are disclosed herein.

Method and apparatus for facial detection using regional similarity distribution analysis

Embodiments of methods, systems, or apparatuses relating to adjusting a brightness level of at least a portion of a backlight of a display device based, at least in part, on one or more measurements of ambient light values.

Adjusting a brightness level of a backlight of a display device

A method of reducing power consumption in a liquid crystal display illuminated by a backlight device includes dimming the backlight and adjusting the intensity of the image to compensate for the dimmed backlight. A dimming factor for the backlight is based on a clipping point determining from the pixel intensity distribution of the image signal. The intensity of the image is adjusted based on the dimming factor, wherein a first tone mapping function is used to adjust pixel intensities below an intensity threshold and a second tone mapping function is used to adjust pixel intensities above the intensity threshold.

LCD backlight dimming, LCD/image signal compensation and method of controlling an LCD display

Embodiments of methods, systems, or apparatuses relating to adjusting a brightness level associated with at least a portion of a backlight of a display device.

Method, system or apparatus for adjusting a brightness level associated with at least a portion of a backlight of a display device

Enhancement of an image includes adjusting its brightness and then adjusting the contrast of the brightness adjusted image. Adjusting the brightness uses an estimation of real world luminance. Contrast adjustment involves extracting background and contrast information, adjusting the contrast information by an adjustment factor based on the background information and combining the background corrected contrast information to obtain an output image.
