摘要： The invention relates to a method for processing an image displayed by a display device comprising at least one light source and one light valve. It comprises the following steps: applying a compression factor C to the grey levels of the image video signal that are higher than a threshold value NG1, the said threshold value being lower than the peak grey level value (NGmax) of the image video signal, adjusting the luminance of the light produced by the light source to the luminance value corresponding to the peak grey level (NG′max) of the image after compression, multiplying the video signal delivered to the light valve by an expansion factor D equal to the ratio of the peak grey level of the image before compression (NGmax) over the peak grey level of the image after compression (NG′max).

摘要： A particular implementation accesses a disparity value for a particular location in a picture, the disparity value indicating disparity with respect to a particular resolution. The particular implementation modifies the accessed disparity value based on multiple resolutions to produce a modified disparity value. Another implementation accesses a disparity value for a particular location in a picture, the picture having a particular resolution, and the disparity value indicating disparity with respect to another resolution that is different from the particular resolution and that is based on multiple resolutions. A further implementation modifies the accessed disparity value to produce a modified disparity value indicating disparity with respect to the particular resolution.

摘要： What is proposed is a method for the color correction of digital image data generated by spectral absorption of white light in color filters of a first representation means. Color film material, in particular, is taken into consideration as the first representation means. For this purpose, firstly the primary color values R, G, B of the image data on the color film are detected. Said primary color values R, G, B are corrected in order to generate secondary color values R′, G′, B′ which are related to a second representation means, for example a monitor. This correction involves taking account of the absorption of light in secondary densities of the colorants of the film material which form the color filters of the first representation means. For this purpose, a plurality of absorption spectra are generated for different densities of the colorants. Finally, the spectral profile of the absorption spectra of the colorants influences the correction of the primary color values for generating the secondary color values. This follows the aim of achieving a maximum correspondence between the color representation with the first representation means and the color representation with the second representation means.
摘要翻译：提出了一种用于通过第一表示装置的滤色器中的白光的光谱吸收产生的数字图像数据的颜色校正的方法。作为第一表示装置，特别考虑到彩色胶片材料。为此，首先检测彩色胶片上的图像数据的原色值R，G，B。校正所述原色值R，G，B以产生与第二表示装置（例如监视器）相关的次色值R'，G'，B'。该校正涉及考虑到形成第一表示装置的滤色器的膜材料的着色剂的二次密度中的光的吸收。为此，为着色剂的不同密度产生多个吸收光谱。最后，着色剂的吸收光谱的光谱图影响了用于产生二次色值的原色值的校正。这是为了实现与第一表示装置的颜色表示和具有第二表示装置的颜色表示之间的最大对应关系的目的。

摘要： System for the sequential illumination of an imager comprising a color wheel comprising at least two coplanar subsets of three colored segments The color wheel comprises at least one subset of segments of primary colors 61R, 61G and 61B, and one subset of segments of composite colors. The subset of segments of composite colors comprises a segment transmitting in the ranges of wavelengths corresponding to red and to green, a segment transmitting in the ranges of wavelengths corresponding to green and to blue, and a segment transmitting in the ranges of wavelengths corresponding to red and to blue. Thus, the luminosity of image display systems is improved, and the phenomenon of “color break-up” is appreciably reduced. Corresponding projection appliance.

摘要： The present invention relates to an apparatus and a device for displaying images. It is known to inlay a pattern of watermark type into the sequence of images to be displayed so as to combat the copying of images by picture-taking. This inlaying consists in modulating the intensity of the pixels of the pattern about the value to be displayed at a high frequency which renders the pattern invisible to the human eye but which generates artefacts on the sequence filmed by the camcorder. This technique poses problems when the sequence of images to be displayed comprises scenes in motion. The pattern appears since the integration carried out by the eye at the moment of display of the images is not correct. According to the invention, it is proposed that the patterns to be inlayed be motion compensated.

摘要： The present invention relates to a method of improving the luminous efficiency of a sequential-colour matrix display, the display being driven using an addressing method of the pulse width modulation or PWM type. This method comprises, for each pixel of a subframe, the following steps: comparison of the pixel colour value of the preceding subframe with a reference value so as to provide an overlap value depending on the period of overlap with the current subframe; if the pixel colour value of the current subframe less the overlap value gives a positive value, a time offset is added to the pixel colour value of the current subframe; if the pixel colour value of the current subframe less the overlap value gives a negative value, the pixel colour value of the current subframe is forced to be zero. The invention applies to LCOS or LCD displays.
摘要翻译：本发明涉及一种提高顺序彩色矩阵显示器的发光效率的方法，该显示器使用脉冲宽度调制或PWM型的寻址方法来驱动。该方法对于子帧的每个像素包括以下步骤：将前一子帧的像素颜色值与参考值进行比较，以便根据与当前子帧的重叠周期提供重叠值; 如果当前子帧的像素颜色值减去重叠值给出正值，则将时间偏移量加到当前子帧的像素颜色值上; 如果当前子帧的像素颜色值减去重叠值给出负值，则将当前子帧的像素颜色值强制为零。本发明适用于LCOS或LCD显示器。
