摘要： A method and apparatus for motion blur and ghosting prevention in imaging system is presented. A residue image is computed by performing spatial-temporal filter with a set of absolute image difference of image pairs from input images. A noise adaptive pixel threshold is computed for every pixel based on noise statistics of image sensor. The residue image and the noise adaptive pixel threshold are used to create a motion masking map. The motion masking map is used to represent motion and non-motion pixels in pixels merging. The pixels merging step is performed to generate an output image by considering the motion pixels where the motion pixels are performed separately. The resulting output image having no or less motion blur and ghosting artifacts can be obtained, even the input images having different degree of motion blur between each of the image, while the complexity is low. It is preferred that the current invention is applied in the Bayer raw domain. The benefit is reduced computation and memory because only 1 color component is processed for each pixel. Another benefit is higher signal fidelity because processing in the Bayer raw domain is unaffected by demosaicing artifacts, especially along edges. However, the current invention can also be applied in RGB domain.
摘要翻译：提出了一种成像系统中运动模糊和重影防止的方法和装置。通过执行具有来自输入图像的图像对的一组绝对图像差异的空间 - 时间滤波来计算残差图像。基于图像传感器的噪声统计，为每个像素计算噪声自适应像素阈值。残差图像和噪声自适应像素阈值用于创建运动掩蔽图。运动屏蔽图用于表示像素合并中的运动和非运动像素。执行像素合并步骤，通过考虑分别执行运动像素的运动像素来生成输出图像。即使在复杂度低的情况下，甚至在每个图像之间具有不同的运动模糊度的输入图像也可以获得没有或更少的运动模糊和重影假象的结果输出图像。本发明优选应用于拜耳原始领域。该优点是减少了计算和存储器，因为每个像素只处理1个颜色分量。另一个好处是更高的信号保真度，因为拜耳原始域中的处理不受去马赛克伪像的影响，特别是沿着边缘。然而，本发明也可以应用于RGB域。

摘要： A method for appropriately defining standards for implementing an MPEG-n intellectual property management and protection (IPMP) system introduces IPMP Tool Information located at the beginning of the content stream, and an IPMP Tool management function as a pre-processing module located at the start of the content decoder, and retrieves IPMP Tools based on the IPMP Tool Information. To improve security and enable interoperability between terminals in different IPMP systems, a two-layer security structure and user authentication output format are further defined. Implementation on terminals of different complexity is enabled by further defining different profiles for IPMP Tool retrieval.

摘要： The present invention relates to content and IPMP tool transfer among distributed IPMP devices. A set of messages is defined for distributed IPMP devices. These messages include content transfer message, IPMP tool transfer messages, as well device ID broadcasting messages. Using these messages, distributed devices can use a standard set of messages to establish a network, and exchange content protected by IPMP in an inter-operable way. It is also related to carriage of rights in MPEG system, especially in MPEG-4 system. Rights ES (Elementary Stream) is defined in MPEG-4 system, to carry rights information. The Rights ES is also attached with information including whether the rights carried in the ES is proprietary or not, and/or what should be the rights management tool to handle this Rights ES. With that, terminal can be built in an inter-operable way, and retrieve rights from a standardized position.

摘要： A method of encoding a local time base embedded in the compressed data is disclosed. The local time base is encoded in two parts. The first part has a modulo time base that indicates the specific interval in the reference time base and the second part has a time base increment relative to the reference time. Two forms of time base increment is used to allow for the possibility of different encoding order and displaying order. A mechanism for the synchronization of multiple compressed streams with local time base is also described. A time base offset mechanism is also used to allow finer granularity synchronization of the multiple compressed streams.
