METHODS FOR SELECTING BACKLIGHT ILLUMINATION LEVEL AND ADJUSTING IMAGE CHARACTERISTICS

摘要

The present invention comprises methods for selecting backlight illumination level and adjusting image characteristics. An image (170) is sent to an image analyzer (172) to determine image characteristics relevant to tone scale map and source light calculations. Said image characteristics comprise a histogram of maximum image code values for each color plane and for each block of the image (170). The data from said histogram are sent to a source light calculator (177) for determination of an appropriate source light illumination level.
