摘要:
The invention provides a tracking apparatus and a tracking method by which an imaging object can be set without any special manual operation by a user. An imaged image is supplied to an imaging object setting section via an imaging object processing section. In the imaging object setting section, a motion detection section calculates a difference value between images of successive two frames and detects a motion of an image based on the difference value. Then, a portion of the image from which the motion is detected is set as an imaging object to be tracked.

A tracking apparatus for tracking an imaging object, includes: imaging means for imaging the imaging object; driving means for driving the imaging means to perform panning and tilting; position detection means for detecting a position of the imaging object in an image outputted from the imaging means; automatic tracking means for calculating a displacement amount between the position of the imaging object detected by the position detection means and a reference position in the image outputted from the imaging means and controlling the driving means based on the displacement amount so that the position of the imaging object may coincide with the reference position to automatically track the imaging object; and reference position setting means for setting the reference position.

A motion detection system for detecting motion in input images. One of the input images is stored for use as a reference image for motion detection processing. The reference image is updated according to any one of a multiple of possible updating modes. Images input after establishment of the reference image are compared to the reference image and the detection of motion in the input images is based on the comparison. The interval in which motion in the input images is detected is extended according to a predetermined extension time.

A subject tracking apparatus in which the target is tracked further stably by effectively eliminating the erroneous judgment due to the effects from the object which resembles the target, the luminance change, and objects having different shapes. Each of the R-Y signal and the B-Y signal at setting the feature of target is modeled by the luminance, so as to detect the features without concerning the hue to the luminance change. Also, the R-Y signal and the B-Y signal are directly modeled, so as to detect the features in the same way regarding the subject with colorless since hue has no effect on it. Since it becomes unnecessary to adjust the parameter strictly by modeling in regard to the permissible error, the target can be tracked stably even the luminance changes.

An information processing apparatus includes an obtaining unit configured to obtain stream data, the stream data including one or more events captured by an imaging device and arranged in an order that is independent of a time order of time periods of capturing of the individual events, and to obtain additional information including start times and end times of the time periods of capturing of the individual events; a recording controller configured to exercise control so that the stream data obtained by the obtaining unit is recorded on a recording medium; and a generating unit configured to generate a date playlist on the basis of the additional information, the date playlist allowing individual reproduction of titles associated with individual dates, each of the titles being a collection of one or more events having the same date and sorted in order of time among the events captured by the imaging device.
摘要:
An apparatus and method for recording and reproducing a sound (i.e. audio) signal corresponding to a video signal at a higher than normal speed. The method delimits a sound signal reproduced at a recording medium at a speed higher than a normal speed into successive processing unit periods. For each processing unit period, sound absence portion(s) of the reproduced sound signal are deleted (or partially deleted) within a range corresponding to a normal speed reproduction. Sound presence portions preceding and following the deleted absence portions are joined or compressed to produce a recognizable sound signal.

The invention provides an information processing apparatus and method as well as a providing medium by which a period for reproduction of reproduction data at fixed intervals can be calculated to reproduce the reproduction data in a fixed period. First, a TOC of reproduction data is read out and a frame number of the reproduction data is calculated. Then, a readout time within which the reproduction data for one frame are read out from a recording medium is calculated. Thereafter, a sum total of reading position movement times when the reproduction data for L frames are read out is calculated. Then, a sum total of reproduction processing waiting times when the reproduction data for the L frames are read out is calculated. Then, the sum totals of the readout times, reading position movement times and reproduction processing waiting times are added to calculate a total time. Finally, a reproduction data transfer period is calculated based on the total time, and reproduction of the reproduction data is performed at time intervals corresponding to the reproduction data transfer period.

A commercial candidate section detector detects a commercial candidate section on the basis of a quiet section and a scene change point. A commercial characteristic quantity detector judges whether the commercial candidate section has various characteristics of commercials, and adds a predetermined value to an commercial characteristic value on the basis of the judgment result. The commercial characteristic quantity detector compares the final commercial characteristic value with a predetermined threshold value, and judges on the basis of the comparison result whether the commercial candidate section is a commercial section.
摘要:
A recording apparatus configured to receive analog video and audio signals, digitize and compress the same, and record the compressed audio and video signals on a digital recording medium such as an optical disk. As the audio and video signals are received and recorded, time segments of the audio signals are analyzed for certain features such as whether the time segment corresponds to instrumental music, vocal music or conversational speech. A table of contents is then generated corresponding to the feature analysis and digitally stored on the storage medium. As a result, the recorded audio is characterized over time, e.g., on a frame by frame basis. A high degree of versatility is thereby provided in the playback process, such as the ability to skip portions having certain audio types or to quickly scroll to desired portions of the recorded audio programs. Reproducing apparatuses enable the user to selectively reproduce segments of the recorded audio and video.
