    摘要： A coded digital video signal is obtained by dividing a digital video signal into plural pages each composed of K fields of pixel data, decomposing pixel data in each two pages into plural blocks each composed of a predetermined number of pixel data, and encoding the pixel data in each block by bit rate reduction encoding and error correction encoding. The thus obtained coded digital video signal is reproduced or transmitted and then subjected to a concealment process. The concealment process includes decoding the coded digital video signal to obtain reproduced blocks of pixel data and to detect an error block containing an error among the reproduced blocks, composing the reproduced blocks to obtain plural reproduced pages of pixel data, and concealing error pixel data contained in the error block in each two reproduced pages. Error pixel data in a first page is concealed using pixel data in a previous page, and error pixel data in a second page is concealed using pixel data in a succeeding page.

    摘要翻译： 通过将数字视频信号分割成由K个像素数据构成的多个页面来获得编码数字视频信号，将每两页中的像素数据分解为由预定数量的像素数据组成的多个块，并且对像素数据进行编码 在每个块中通过比特率降低编码和纠错编码。 如此获得的编码数字视频信号被再现或发送，然后进行隐蔽处理。 隐藏处理包括对编码的数字视频信号进行解码以获得再现的像素数据块，并且检测包含再现块中的错误的错误块，构成再现块以获得多个再现页面的像素数据，以及隐藏包含的错误像素数据 在每两个重现页面的错误块中。 使用前一页中的像素数据隐藏第一页中的错误像素数据，并且使用后续页面中的像素数据隐藏第二页中的误差像素数据。

    摘要： A data source has a data converting part for converting inputted data to predetermined data packets. A data buffer stores the data packets. A descriptor list stores a descriptor to which predetermined addresses are added, where a method of sending the data packets is described. A FIFO stores the predetermined addresses in a first-in first-out mode. A data sending part receives start instructions from the data converting part, refers to a predetermined address in which reference is not made yet in the FIFO, fetches data packets corresponding to the descriptor from the data buffer in accordance with a method of sending the descriptor indicated by the predetermined address, generates a send packet from the data packet and outputs the data packet. An end-of-send notice to the data converting part is also send when the output of the send packet is ended.

    摘要： A image signal processing apparatus and method for static image display are provided. Deformation at an edge of an image can be reduced by eliminating a temporal factor and vertical resolution can be retained even after data supplementation. In the process of compressing and decompressing interlace-scanned image data, one of two fields of a frame is selected by a field selector, image data is supplemented and reproduced based on the selected field data by a supplementor, and image data is outputted as a static image without deformation. As a result, more bits can be allocated for encoding by selecting and compressing one field data only and it leads to a higher quality image display. Furthermore, display deformation can be reduced by supplementing high frequency components as zero in the decompression processing.

    摘要： Afforded is an optical element holder allowing high-accuracy stereo images to be taken. The holder includes: a rectangular parallelepiped beam splitter (5) having a rectangular incident surface (12); a pair of mutually opposing holding members (8) into which end portions of the beam splitter along the x-axis are fitted; and a base portion (9) and screws (10) that press on the holding members (8), drawing them toward each other. Each of the holding members (8) has a flat surface portion covering a lateral surface of the beam splitter (5), and a peripheral wall portion standing along the periphery of the flat surface potion. A width, along the x-axis, whereby the peripheral wall portion and a first light-exit surface opposing the incident surface (12) of the beam splitter (5) overlap is greater than a width, in the same orientation, whereby the incident surface (12) and the peripheral wall portion overlap.
