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 (SP 11, 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 (LV 1) 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 (SP 11), 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 (MA) or fall below the minimum level (MI), respectively.

摘要： The invention relates to a dual display device (DD2) for displaying an input image (I) . The dual display device comprises a first display (Dl) and a second display (D2) . The first display is arranged for modulating an image from the second display. The dual display device further comprises a processor (Pr2) which comprises an image splitter (Sp) which splits the input image into an illumination image (Ii) and a reflection image (Ir) according to a retinex algorithm. The reflection image is displayed on the first display and the illumination image is displayed on the second display. Due to the series arrangement of the two displays the input image I is substantially recreated. The illumination image typically is a spatially low-resolution image derived from the input image. A benefit when using the illumination image at the second display is that the smoothed light intensity values of the illumination image lead to a lower average light intensity and thus to a lower power consumption compared to the prior art solution. Additional benefits when using the retinex algorithm for splitting the images are that parallax errors in dual display devices are reduced and that an improved usage of the dynamic range of the dual display device is obtained.
摘要翻译：本发明涉及一种用于显示输入图像（I）的双重显示装置（DD2）。双显示装置包括第一显示器（D1）和第二显示器（D2）。第一显示器被布置用于调制来自第二显示器的图像。双显示装置还包括处理器（Pr2），其包括根据retinex算法将输入图像分割为照明图像（Ii）和反射图像（Ir）的图像分离器（Sp）。反射图像显示在第一显示器上，照明图像显示在第二显示器上。由于两个显示器的串联布置，输入图像I基本上被重新创建。照明图像通常是从输入图像导出的空间上低分辨率图像。在第二显示器上使用照明图像时的优点在于，与现有技术的解决方案相比，照明图像的平滑光强度值导致较低的平均光强度，从而降低功耗。使用retinex算法分割图像时的另外的好处是减少了双显示设备中的视差误差，并且获得了双显示设备的动态范围的改进的使用。

摘要： A color display device, a drive circuit for a color display device, a method, a signal and a computer-readable medium for reducing electro-optical cross talk that occurs in a display that is operated in Spectrum Sequential mode is disclosed. The invention eliminates annoying visible artefacts, such as contouring, noise, or color deviation, which normally are introduced by this cross talk by compensating for the cross talk. According to embodiments of the invention, a drive signal (R',G',B') to drive picture elements of the display is altered in video processing circuitry (MPC, XTC, SC) and/or software, in dependence on one or more properties of different spectra from a light source (23, 24) in the display. The invention is implemented with little extra effort and cost in known LCD displays.

The conversion method comprises: determining (5, 6; 9, 10) in the linear color space (X, Y, Z) a position of the input vector (CIP) with respect to boundaries (CB) of at least two of three gamuts (FG, ELG, ELCG) being defined by transformed display primaries (CP1,..., CPn), wherein the three gamuts (FG, ELG, ELCG) indicate: a full gamut (FG) comprising all colors being reproducible with the m groups of the sub-drive vectors (PDi), an equal luminance sub-gamut (ELG) comprising all colors having equal luminance and being reproducible with each one of the m groups of the sub-drive vectors (PDi), and an equal luminance and equal chrominance sub-gamut (ELCG) comprising all colors being reproducible with each one of the m groups of sub-drive vectors (PDi) each having equal luminance and equal chrominance. Selecting (3; 12, 13) two boundary vectors (CB 1, CB2) on the boundaries (CB) of the three gamuts (FG, ELG, ELCG) to enable the input vector (CIP) to be interpolated from the two boundary vectors (CBl, CB2). Determining (3; 14) an interpolation factor (u) from the position of the input vector (CIP) with respect to the selected two boundary vectors (CBl, CB2). And, interpolating (4; 11) in the display color space the drive vector (PD) representing the color of the input vector (CIP) from the interpolation factor (u) and two boundary vectors (PBl, PB 2) in the display color space corresponding to the selected two boundary vectors (CBl, CB2) in the linear color space.

摘要： A method converts an input image signal (IS) into a drive signal (DS) for driving sub-pixels (SP) of a display device (DD) comprising display pixels (DPI) having at least two sub-pixel groups (SGl, SG2) being able to contribute to luminance information displayed. The conversion comprises a multi-primary conversion (MPC) which receives the input image signal (IS) and which is performed under a constraint (CO). The constraint (CO) is determined (CD) by substantially matching local display luminances (DLl, DL2; DLD) associated with the at least two sub-pixel groups (SGl, SG2) with corresponding local input luminances (Ll, L2; LD) of input pixels (IP) of the input image signal (IS), thereby obtaining a display luminance pattern defined by the display pixels (DPI) corresponding to an input luminance pattern defined by the input pixels (IP) associated with the display pixels (DPI).

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.
