摘要： A driver (DD, SD, PD1, PD2) drives a display panel which comprises a first set of light emitting elements (PL1) and a second set of light emitting elements (PL2). The driver (DD, SD, PD1, PD2) comprises a data driver (DD) which receives a first set of input image signals (R) representing a first color to supply a first set of data signals (RD 1) to the first set of light emitting elements (PL1), respectively. The data driver (DD) further receives a second set of input image signals (B) representing a second color to supply a second set of data signals (BD1) to the second set of light emitting elements (PL2), respectively. A lowpass filter (LPF) is provided to obtain the second set of data signals (BD1) having a bandwidth being smaller than a bandwidth of the first set of data signals (RD1).

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.

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 work-load 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.

摘要： The invention relates to a transcoder (100) for a variable length coded data stream such as an MPEG 2 coded data stream transcoder (100) comprises a receiver (101) which receives the variable length coded data stream. The receiver (101) is connected to a significance processor (107) that determines if a variable length coded coefficient is significant or less significant. The significance processor (107) is connected to a truncation processor (111) which truncates the less significant coefficients. The trancoder further comprises an encode processor (109) which generates a transcoded data stream from the original significant coefficients and the truncated less significant coefficients. All processing may be performed exclusively in the variable length code domain thereby providing a low complexity and high speed transcoder.

摘要： A driver (D) for a matrix display panel (1) with a pixel (Pk) comprising a first and a second sub-pixel (SP11, 12) both having an inertia, receives a first and second input signal (R, G) indicating a first and a second desired brightness transition (BT1, BT2) of the first and second sub-pixel (SP11, 12), respectively. The driver (D) supplies a first and a second drive signal (Ra, Ga) to the first and the second sub-pixel (SP11, 12), respectively. The first and a second drive signal (Ra, Ga) are supplied at a predetermined repetition rate, and levels of the first and the second drive signal (Ra, Ga) are limited between a minimum level (MI) and a maximum level (MA). The predetermined repetition rate may be the frame or line rate. The predetermined period is the reciprocal of the predetermined repetition rate. The driver (D) comprises: a detector (LV1) which detects whether the first drive signal (Ra) within the single predetermined period (Tf) would have to surpass the maximum level (MA) or to fall below the minimum level (MI) in order to compensate for the inertia of the first sub-pixel (SP11), and a level adapter (AC) which increases or decreases a level of the second drive signal (Ga) if is detected that the first drive signal (Ra) would have to surpass the maximum level (A) or fall below the minimum level (MI), respectively.
