Автор: Yuya Fujiwara
Принадлежит: Canon Inc

A moving image capture apparatus generates a data file to record, on a recording medium, an image signal output from an imaging unit, extracts character information from the image signal to be recorded on the recording medium, sets a parameter value used for selection as a file name according to a characteristic of appearance of the character information, calculates an evaluation value from the set parameter value, and sets character information based on the calculated evaluation value as a file name of the image signal. Furthermore, the moving image capture apparatus generates a thumbnail of the file based on an image signal from which character information for which the calculated evaluation value is relatively large has been extracted.

Image pickup means is capable of picking up an image at a first frame rate and a second frame rate that is higher than the first frame rate. A highlight scene is detected by detection means. When detecting the highlight scene, image pickup operation is performed at a high speed mode and an image signal at high frame rate (240 fps) is produced for a period of predetermined time. When detecting no highlight scene, image pickup operation is performed at a normal mode and an image signal at normal frame rate (60 fps) is produced. It is possible to save time and labor for performing a switchover operation of a frame rate when imaging a highlight scene. It is also possible to save power consumption and a capacity of a storage medium.

An acquisition unit reads content including at least, (a) an image signal of an image frame defined by first and second directions, (b) first and second sizes showing sizes in the first and second directions, and (c) an aspect ratio of the second direction to the first direction. An inspection unit inspects whether the content includes a display area specification. A determination unit calculates a third size by multiplying the first size by the aspect ratio and determines a display area of the image frame based on an entire range in the first direction and a range of the third size from a predetermined position in the image frame in the second direction, when the display area specification is not included in the content. A controller performs control so that the display area of the image frame is displayed and a part other than the display area is not displayed.

A high resolution video signal is divided by video division means into a main signal and a sub signal, and the main signal and the sub signal are MPEG-encoded. The stream of the main signal and the stream of the sub signal are divided into 1 GPO or more of frames. First interleave blocks each including 1 GOP or more of the stream of the main signal and second interleave blocks each including 1 GOP or more of the stream of the sub signal are recorded on an optical disk. A high resolution reproduction apparatus reproduces both the first and second interleave blocks to obtain a high resolution video output. A non-high quality picture reproduction apparatus reproduces only the first or second interleave blocks to obtain a standard resolution video output.

A distributed database management system provides a central database resident on a server that contains database objects. Objects, e.g., program guide data, to be replicated are gathered together into distribution packages called “slices,” that are transmitted to client devices. A slice is a subset of the central database which is relevant to clients within a specific domain, such as a geographic region, or under the footprint of a satellite transmitter. The viewer selects television programs and Web content from displayed sections of the program guide data which are recorded to a storage device. The program guide data are used to determine when to start and end recordings. Client devices periodically connect to the server using a phone line and upload information of interest which is combined with information uploaded from other client devices for statistical, operational, or viewing models.

An image rotation method and an image rotation system for a video player are provided. The image rotation method includes the following steps. Firstly, an image rotation request from a terminal is received. Then, a source video file is decoded and a rotation processing operation is performed on the decoded source video file in response to the image rotation request, so that a rotated image of the source video file is displayed. At last, the rotated image is displayed on a display device of the terminal. By the image rotation method and the image rotation system, the image in the video player can be rotated by a specified angle. Consequently, the problems of the conventional video player will be overcome. Moreover, since the problems of causing the compressed and distorted image are eliminated, the quality of the played and displayed image is enhanced. 1. An image rotation method for a video player , the image rotation method comprising steps of:receiving an image rotation request from a terminal;decoding a source video file, thereby acquiring YUV data of the decoded source video file;converting the YUV data into RGB data and rotating the RGB data;converting the rotated RGB data into a YUV data format of an rotated image of the source video file to be displayed; anddisplaying the rotated image on a display device of the terminal.2.

A multimedia time warping system allows a user to store selected multimedia data streams while the user is simultaneously watching or reviewing other multimedia data. Data streams are converted to digital streams for internal transfer and manipulation. A parser and event buffer decouple the CPU from having to parse the digital stream. Video segments are stored on a storage device and when data is requested for display, its video segments are extracted from the storage device and sent to a decoder that converts them into display output signals and delivers the display output signals to a display.
