摘要： The invention relates to a dual display device (DD2) for displaying an input image (I). The dual display device comprising 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 processor (Pr2) which comprises image splitter (Sp) which split 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）的图像分割器（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 comprises a plurality of picture elements (14), at least two light sources, having different radiance spectra and being activated alternately, and color selection means for generating, together with said light sources, primary colors in a color image (Pl, P2). Each of a number of image information sets, each set being related to a color image (P1, P2) to be displayed, are divided into a first subframe (Al, A2), being picture element settings to be maintained during the operation of a first light source, and a second subframe (B1, B2), being picture element settings to be maintained during the operation of a second light source. The polarity of the picture elements (14) is, in an alternating manner, shifted between a first polarity (+) and a second polarity (-). The polarity is shifted in such manner that a first subframe (Al) and a subsequent first subframe (A2) are matched with different polarities (+, -) in order to avoid a polarization in the picture elements (14) which may result in slow response or other artifacts.

摘要： The invention relates to a transcoder (100) for a variable length coded data stream such as an MPEG 2 coded data stream. The 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.

The method determines (1) a valid range (VS) wherein the N drive signals (Pl, ..., PN) have valid values by performing the steps of (i) defining 3 functions representing 3 of the drive signals (Pl, P2, P3) as a function of the remaining N-3 drive signal(s) (P4, ..., PN), and (ii) calculating (1) a common range in a space formed by the N-3 drive signal(s) (P4, ..., PN) wherein each one of the 3 functions has valid values. The method selects (2) a point from the common range to determine the N drive signals (Pl, ..., PN).

摘要： A display device (500) having a plurality of picture cells (502) is controlled by adding a phase change to the regular cyclic inversion scheme. Thereby, it is possible to overcome the drawbacks of DC build-up due to, e.g., de-interlaced images and images comprising rotating symbols and "ticker tape". The control involves receiving an image signal comprising image data relating to the picture cells. A respective electric field across each picture cell is controlled, in dependence on at least the image data, according to a first polarity inversion scheme where the polarity of the electric field is such that polarity inversion occurs at regular intervals, and according to a second polarity inversion scheme concurrent with said first polarity inversion scheme, where the polarity of the electric field such that polarity inversion occurs at pseudo-random intervals.

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.
