摘要： A display control apparatus comprises a video source(105) which provides a video signal comprising frames. The video source (105) is coupled to a compensation processor (107) which filters at least part of a first frame to provide a compensation for perceived motion blur. A display output (109) feeds the compensated video signal to a display (103) which presents the frame. A controller (111) is arranged to control the display (103) such that it radiates light in a sequence of light pulses for each frame where the sequence of light pulses comprising at least some light pulses having different durations. A motion blur processor (113) determines a suitable compensation filter for the perceived motion blur compensation as one that corresponds to an inverse filter of the sequence of light pulses. The use of pulsed light radiation modifies the hold effect filtering such that it can be better and more easily compensated by pre-filtering.

摘要： A color mapping system comprises a detail detector (1) to generate a control signal (CS) which indicates local detail in an input image signal (IS). The system further comprises a color mapper (2) which maps a first image signal (FIS) into a mapped image signal (MIS) under control of the control signal (CS) for locally changing an intensity and/or a saturation of the first image signal (FIS) as a function of the local detail. The first image signal (FIS) is the input image signal (IS) or a low-pass filtered input image signal (LIS).

摘要： Method display device and computer program product that reduces motion blur, flicker and loss of brightness of images shown in non-stoboscopic display devices, such as Liquid Crystal or Light Emitting Diodes displays, in which each image of input video signal is displayed during a display time ti, which is less than or equal to a picture period T. The motion and the characteristics of motion are measured and the display time ti is continuously adjusted between O and T depending on this measured motion and the caracteristics of motion. To further reduce flicker and loss of brightness encountered when reducing the display time, anti-mot on blur filtering of the input video signal is performed, where the display time and the amount and sort of filtering is jointly controlled based on the measured motion and characteristics of motion.

The method comprises obtaining (S2) a set (15) of sub-pixel values (2, 3, 4) for generating desired perceptive characteristics for said pixel and determining (S3) a modified set (16) of sub-pixel values (2', 3', 4') for generating modified perceptive characteristics for said pixel. This modified set of sub-pixel values is based on information (14)regarding the sub-pixel defect so as to be implementable in the display, and has values chosen to reduce an error perceived by a user. The modified values are then implemented (S4) in the display. The display is preferably of the kind where each pixel comprises a set of primary sub-pixels each emitting a primary color and at least one additional, redundant sub-pixel for emitting an additional color, such as a RGBW display.

摘要： A method of converting a three primary color input signal comprises a first, a second, and a third input signal (Cl, C2, C3) into a four primary color drive signal comprising a first, second, third, and fourth drive signal (Pl, P2, P3, P4) for driving four primary colors of a multi-primary color additive display (3). Three functions (Fl, F2, F3) representing the first, second, and third drive signal (Pl, P2, P3) as a function of the fourth drive signal (P4) are defined. The intersection values (P4i) of the fourth drive signal (P4) are determined at a set of intersections of: the three functions (Fl, F2, F3) mutually, and of the three functions (Fl, F2, F3) and a line (F4) defined by the fourth drive signal (P4) being equal to itself, wherein only the intersection values (P4i) of functions having opposite signs of their first derivative are relevant. The associated first, second and third drive signals (Pl, P2, P3) are calculated at (i) the intersection values (P4i) of the fourth drive signal (P4) to obtain calculated values (CVl, CV2, CV3), and (ii) at boundary values (P4min, P4max) of a valid range (VR) of the fourth drive signal (P4) wherein all drive signals (Pl, P2, P3, P4) have valid values. The values of interest (CVl, CV2, CV3, P4i) comprising the intersection values (P4i) of the fourth drive signal (P4) and the associated calculated values (CVl, CV2, CV3) are determined. The maximum value (Vmax) or minimum value (Vmin) of the values of interest (CVl, CV2, CV3, P4i) at the intersection values (P4i) are calculated. And finally, the intersection value (P4i) at which the maximum value (Vmax) or minimum value (Vmin) is minimum or maximum, respectively, is selected.

摘要： Transform based coders are frequently used in digital signal processing. The present invention relates to a method of communicating at least one block of data from a first functional element (3; 4; 7; 12; 14) within a transform based coder (1) or decoder (10) to a second functional element (4; 5; 7; 8; 14; 15) within the coder or decoder, where the block of data comprises a row-column structure of data coefficients. A significant communication workload occurs between individual elements of the coders and decoders. The present invention seeks to reduce this workload by making an effort to communicate only non-zero coefficients within a cartesian bounding box of a block between various functional units in a decoding or encoding scheme by reducing the size of the at least one block of data to produce a reduced size data block by elimination (31) of one or more rows and/or columns of substantially zero valued coefficients, and communicating (32) the reduced size data block from the first functional element to the second functional element.
