Abstract: A method for reproducing a scene by a time shift is provided in which, by transferring a bookmark created by one viewer to an other viewer, the other viewer can also see a scene that the one viewer desires to see and the scene that the one viewer desires to see can be seen commonly together with the other viewer. To reproduce a recorded moving picture, a scene worthy of note is accessed by using the bookmark. When moving picture information is recorded, picture recording time of a specified screen region is stored in a manner that picture recording actual time of a desired scene is associated with the bookmark and, when reproduction is made, access is made to the scene based on time between picture recording actual time of the scene and of the specified picture screen region and image information of the specified picture screen.

Abstract: A method and an apparatus for synchronized play back of audio-video signals, even when plural digitally compressed audio data are separated and played back, avoid time lag or lead of reference time after the audio data are changed over and can improve the performance of play back of audio data synchronizing with video data, is provided. An apparatus for synchronized play back of audio-video signals decodes and plays back and displays plural digitally compressed audio data and digitally compressed video data. When the audio data to be decoded are changed over, a reference time generator calculates reference time base on the amount of played back data of the changed over decoded audio data. With this reference time, a synchronizing controller controls a video decoder and makes the decoded video data and the changed over audio data synchronize and plays back and displays the audio data and the video data.

Abstract: A variable bit-rate encoding device is provided that can perform a variable bit-rate encoding process at high rate. The subtracter 103 calculates a predictive error between compressed frame data and motion-compensated reference frame data and then outputs it to the code-amount allocator 107. The code-amount allocator 107 calculates and stores the power for each unit section of a predictive error. Thus, at the time the image data has been completely processed, a target code amount allocated to each unit section in a second pass encoding is decided based on the power of a predictive error of the whole image data and based on the power of a predictive error for each unit section. The motion vector memory 114 stores a motion vector for each macroblock. Upon an actual second pass encoding, the motion compensator 115 motion-compensates the reference frame input from the frame memory 116 according to the motion vector value and then outputs the motion-compensated reference frame to the subtracter 113.

Abstract: In an image sensor chip (A), the number N of the image reading picture elements is defined as N=n·k (other than an integer multiple of 16). The n represents the number of image signals processed as a group when the image signals from the light receiving elements are subjected to level correction on a group-by-group basis. The k is the minimum: integer satisfying O<(n·k−g·p)<n. The g is the resolution defined as the number of image reading picture elements per predetermined unit length. The p is the minimum difference between required different reading widths as calculated on the basis of said unit length. When a plurality of such image sensor chips (A) are arranged in an array, the excess ratio of the array length of the image sensor chips (A) relative to a required reading width can be rendered constant.

Abstract: A memory device memorizes the multiplex data of compressed picture data and compressed subordinate picture data. A data-separating section separates the subordinate picture data and a subordinate-picture-decoding section decodes the separated subordinate picture data into the run-length-decoded data. A subordinate-picture-data-converting section changes the format of the decoded subordinate picture data to reduce the number of table-looking-up operations required for a synthesizing process and removes the redundant pixel data which is included in the decoded subordinate picture data and whose contrast values are zero and hence which can not be seen even if synthesized. A picture-synthetic section synthesizes the subordinate picture data converted by the subordinate-picture-data-converting section on the main picture at the designated synthesizing positions.

Abstract: An analog image signal from an input terminal 101is converted in an ADC 102 to digital data, then stored in a frame memory 103, then subjected to compression processing in a compression processing module 104, and then recorded in a recorder 105. The compressed data recorded in the recorder 105 is read out, then subjected to decompression processing in a decompression processing module 106, and then stored in a frame memory 107. The operation of the compression processing module 104 is controlled by a frame rate controller 110. Thus, the problem of frame data drop-out or reproducing processing delay occurrence when it becomes unable to obtain full frame real time frame capturing, real time compression and real time decompression due to CPU performance insufficiency is solved.
