<p>The enhancement of images to be displayed on a liquid crystal display (LCD) comprises remapping initial pixel values to remapped pixel values in accordance with an equation that raises an initial pixel value to an exponent of a modified gamma value ratio. The modified gamma value ratio is based on a backlight level, an ambient light level and/or other light levels associated with the LCD. The enhancement can selectively increase image brightness in response to a reduction in the backlight level or an increase in the ambient light level, or selectively reduce image brightness in response to a reduction in the ambient light level. The image or a portion of the image can be enhanced. An image portion to be enhanced can be a user-specified bounding box or one or more windows selected by a user or associated with one or more applications running on a computing device.</p> |
