摘要： 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.

摘要： For two or more versions of a video with different spatial, temporal or SNR resolution, scalability can be achieved by generating a base layer (BL) and an enhancement layer (EL). 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.
摘要翻译：对于具有不同空间，时间或SNR分辨率的视频的两个或多个版本，可以通过生成基本层（BL）和增强层（EL）来实现可扩展性。当具有比可显示更高的颜色位深度的视频版本可用时，通常的解决方案是色调映射。对于具有不同颜色位深度的两个或多个版本使用不同颜色编码的情况，提出了一种更有效的压缩方法。本发明基于可用颜色通道之间的联合层间预测。因此，也可以使用具有不同颜色位深度的两个或多个版本使用不同的颜色编码的颜色位深度可缩放性。在这种情况下，层间预测是基于所有颜色分量的联合预测。预测还可以包括颜色空间转换和伽马校正。

摘要： 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 SVC standard allows spatial inter-layer prediction, wherein a residual in the EL is generated which is then intra coded. Another spatial intra-coding mode for EL is pure intra coding (I_NxN). The invention discloses encoding modes wherein the output of enhancement layer decoding is an inter-layer residual. To get the final enhancement layer decoded sequence, the color bit depth inter-layer prediction version of the base layer, which is bit depth upsampled reconstructed base layer information, is added to the inter-layer residual which is decoded from the enhancement layer bit stream.

摘要： A display device produces colour images by sequentially projecting monochromatic images. Multispectral light is projected via optical means and a filter arrangement with changeable primary colour filters onto an imaging device. For each primary colour the imaging device produces a number of constant-length pulses corresponding to a desired brightness level. The pulse length is chosen to be as short as possible for a first primary colour. The pulse length for the other primary colours is adapted according to the respective share of the corresponding colour filters in the colour wheel. The time during which secondary colours are produced due to a transition between two primary colour filters is increased by increasing the aperture of the optical means, by spatially relocating the focal point of the optical means for a disc-like filter arrangement, or by accordingly adding pure colour light at the onset and the end of a transition between two colour filter segments which produces secondary colour light. Secondary colour light is used to increase the brightness of the projected image.

摘要： An imager achieves a desired image resolution by successively reproducing partial images which complement each other. The imager assigns pixels from an input image to the respective partial images according to complementing patterns that correspond to the pixel pattern of the imager. The imager reproduces the complementing pattern at different spatial positions, such that the complementing patterns merge. In order to avoid perceived double imaging of moving objects the image signal provided to the imager is assembled from an original image and a motion compensated interpolated image, which is derived from at least two consecutive images. Accordingly, every other partial image that is reproduced is derived from an interpolated image and takes into account movement of objects in the image that takes place between two consecutive images. In one embodiment the partial images are re-combined into one full image in a sequence that anticipates the distribution of the pixels used in the imaging device.

摘要： A driving scheme for colour wheels that use primary or primary and secondary colours reduces the colour separation by temporally locating the light pulses required for generating a desired colour as close together as possible. In one embodiment, the pulse length increases in a direction away from a transition between a secondary colour filter and a corresponding complementary primary colour filter for light pulses of the respective colours. In one embodiment the total required light output is composed of shorter light pulses that are distributed among all suitable combinations of colours that are available from the colour wheel.
