20090278770 | Active matrix organic light emitting display (amoled) device - The present invention relates to an active matrix OLED (Organic Light Emitting Display) device. It comprises a matrix of luminous elements associated to different colour components (red, green, blue). According to the invention, the connection of the row driver and/or data driver to the luminous elements of the matrix is modified. Each output of the row driver is connected to luminous element associated to a same colour component (red or green or blue). | 11-12-2009 |
20100027619 | METHOD AND APPARATUS FOR ENCODING AND/OR DECODING VIDEO DATA USING ADAPTIVE PREDICTION ORDER FOR SPATIAL AND BIT DEPTH PREDICTION - A scalable video bitstream may have an H.264/AVC compatible base layer (BL) and a scalable enhancement layer (EL), where scalability refers to color bit depth. The H.264/AVC scalability extension SVC provides also other types of scalability, e.g. spatial scalability where the number of pixels in BL and EL are different. According to the invention, BL information is upsampled (TUp,BDUp) in two logical steps in adaptive order, one being texture upsampling and the other being bit depth upsampling. Texture upsampling is a process that increases the number of pixels, and bit depth upsampling is a process that increases the number of values that each pixel can have, corresponding to the pixels color intensity. The upsampled BL data are used to predict the collocated EL. A prediction order indication is transferred so that the decoder can upsample BL information in the same manner as the encoder, wherein the upsampling refers to spatial and bit depth characteristics. | 02-04-2010 |
20100128786 | METHOD AND APPARATUS FOR ENCODING VIDEO DATA, METHOD AND APPARATUS FOR DECODING ENCODED VIDEO DATA AND ENCODED VIDEO SIGNAL - For two or more versions of a video with different spatial, temporal or SNR resolution, scalability can be achieved by generating a base layer and an enhancement layer. When a version of a video is available that has higher color bit depth than can be displayed, a common solution is tone mapping. A more efficient compression method is proposed for the case where the two or more versions with different color bit depth use different color encoding. The present invention is based on joint inter-layer prediction among the available color channels. Thus, color bit depth scalability can also be used where the two or more versions with different color bit depth use different color encoding. In this case the inter-layer prediction is a joint prediction based on all color components. Prediction may also include color space conversion and gamma correction. | 05-27-2010 |
20100220237 | METHOD AND SYSTEM FOR COLOR CORRECTING DISPLAYS WITH DIFFERENT COLOR GAMUTS - There are provided a method and system for color correcting displays with different color gamuts. The method includes performing color correction on source picture content, using at least one of a non-reference type display having a non-reference color gamut and a reference type display having a reference color gamut. The performing step includes mastering the source picture content to provide mastered color corrected picture content for display on the reference type displays having a reference color gamut. The performing step further includes generating metadata for a subsequent inverse color gamut mapping that color transforms the mastered color corrected picture content for display on non-reference type displays having a non-reference color gamut. The subsequent inverse color gamut mapping is an inverse operation of a color gamut mapping applied during the color correction to obtain the mastered color corrected picture content for display on the reference type displays having the reference color gamut. The source picture content is mastered only for the reference type displays having the reference color gamut. | 09-02-2010 |

20100289810 | METHODS AND SYSTEMS FOR DISPLAYS WITH CHROMATIC CORRECTION HAVING DIFFERING CHROMATIC RANGES - There are provided methods and systems for color correcting displays with different color gamuts. A method includes performing an initial color correction on source picture content using a reference type display having a reference color gamut to obtain mastered color corrected picture content for display on reference type displays having the reference color gamut. The method further includes determining a first set of metadata defining a color gamut mapping specification for a color gamut mapping from a non-reference type display having a non-reference color gamut to the reference type display. The method also includes performing a subsequent color correction using the non-reference type display and the mastered color corrected picture content to create a second set of metadata directed to non-reference type displays having the non-reference color gamut. The method additionally includes generating a final set of metadata from the first set of metadata and the second set of metadata, for a subsequent color transform that color transforms the mastered color corrected picture content for display on non-reference type displays for consumer consumption. The source picture content is mastered for consumer consumption only for the reference type displays having the reference color gamut. | 11-18-2010 |
