摘要： A method for processing color image data that enables to optimally render a color image on a target device. The method incorporates a color gamut mapping step, where the amount of gamut mapping is adapted dynamically, in dependence of at least a color saturation value of the input pixel. Preferably, also a luminance value of the input pixel is used. The adaptive gamut mapping incorporates correction of saturation, and preferably also hue and white point, of the image data. The color gamut of the target device is used to the fullest possible extent, while clipping and loss of local details in highly saturated areas of the input image is largely prevented.

摘要： A display method comprises the steps of generating (1) images comprising source data (SDA) and source frame synchronization instants (SSI) having a source frame rate (SFR). The source data (SDA) is stored (2) in a frame memory (5) under control of a first address pointer (AP I) having a start address (DSA) being determined by the source frame synchronization instants (SSI). During a read period (RP), display data (DDA) is read (2) from the memory (5) under control of a second address pointer (AP2) having a start address (SSA) being determined by display frame synchronization instants (DSI) having a display frame rate (DFR). The display data (DDA) is displayed (3) on a matrix display (4). The source frame rate (SFR) or the display frame rate (DFR) is controlled (2) to obtain, in a stable situation, the first address pointer (AP I) and the second address pointer (AP2) starting with an offset in time (TO) which has a fixed polarity during the read period (RP).

摘要： A method for processing a frame of image data, wherein the image data is amplified by a gain factor determined in dependence of a number of sub-pixels within said frame of image data having a luminance above a first threshold value. The resulting gain factor allows for optimal amplification of the image data without loss of local detail. This leads to a better perceived image quality. In a preferred embodiment, the gain factor is simultaneously used for reducing the backlight intensity in a backlit LCD device. Thereby, the perceived image quality is similar to that of the unprocessed image data, however the power consumption of the LCD backlight is reduced substantially.

摘要： The invention concerns a device and method for converting and supplying a display driving unit with luminance values as well as a portable electronic device and a display unit including the converting device. The device includes an input (33, 35, 37), which receives a first value representing a luminance level with a first word length. It also includes a conversion unit (34, 36 38), that converts the first value into second and third values. These values together represent the luminance level represented by the first value and have a second word length. The second word length is shorter than the first word length. The device also includes a subfield control unit (32), which supplies the second and third values to the display driving unit during a frame period of the display. The time taken up by each converted value is a subfield of the frame. The subfield of the third value is longer than the subfield of the second value.
