METHODS FOR SELECTING BACKLIGHT ILLUMINATION LEVEL AND SETTING UP IMAGE CHARACTERISTICS Russian patent published in 2012 - IPC G09G3/36

Abstract RU 2463673 C2

FIELD: information technology.

SUBSTANCE: image (170) is sent to an image analyser (172) to determine image characteristics essential for calculating the tone scale map and backlight. Said image characteristics contain a histogram of maximum code values of the image for each colour plane and for each unit of the image (170). Data from said histogram are sent to a backlight calculator (177) to determine the suitable backlight illumination level.

EFFECT: compensation for low illumination of a light source.
