摘要： A method of dynamic gamut control is provided for a display having a multi- spectral (typically multi-color) backlight, and sub-pixels corresponding to the different backlight spectra and at least one common sub-pixel. The display may for example be an RGBW display having an RGB backlight. The method comprises iteratively calculating the minimum required backlight intensities that will allow all (selected) color points of an image to be represented by the display. The determination for a light source of the backlight is based on determinations of intensities determined for other light sources in a previous iteration. In some embodiments, the approach allows for a clipping of a number of the color points. The invention may reduce power consumption while maintaining a high image quality and can be implemented computationally very efficiently.

摘要： An apparatus generates a derived image signal for a display (101) having a backlight (105) and a light modulating display panel (107). An input image is represented by pixel values in accordance with a color representation having a first reproducible gamut. A backlight driver (111) determines a backlight driving signal corresponding to a presentation of the image on the display (101) in accordance with an image rendering criterion. A processor (113) determines a first set of primary color vectors corresponding to a rendering gamut in response to the backlight driving signal. It then determines a second set of color vectors defining directions in which a degree of freedom for adding luminous energy to the derived image signal exists, given as a constraint the first set of primary color vectors. An image enhancer (115) performs an image enhancement which increases local color modulator drive values for local colors in accordance with the degree of freedom.

摘要： A controller for a multi-primary display having M>3 primaries receives a set of input N-primary image color defining values comprising drive values for N primaries for each pixel. A compensator (317) generates a set of compensated N-primary image color (N>=3) defining values by applying a luminance compensation to the values of the set of input N-primary image color defining values where the luminance compensation for each pixel depends on the chromaticity of the pixel. A backlight processor (311) determines backlight levels in response to the compensated N-primary image color defining values. A modifier (313) then generates modified N-primary image color defining values by adjusting the input or the modified N-primary image color defining values or the for the backlight level and a primary converter (315) converts the modified N-primary image color defining values into multi-primary drive values for the display. The approach may e.g. reduce clipping for multi-primary displays with dynamic backlight control by introducing a low complexity pre- processing luminance compensation to existing equipment.
