摘要:
An electronic apparatus includes a detecting unit and a categorizing unit. The detecting unit compares each of a plurality of frames that constitute each of a plurality of video contents with one another, and detects a video feature generated by one of a camera operation and video editing from each of the plurality of video contents. The categorizing unit judges, based on the detected video feature, a visual activity level of a video contained in each of the plurality of video contents, and categorizes each of the plurality of video contents based on the judged activity level.

An electronic apparatus includes an extracting unit, a retrieving unit, a detecting unit, and a controlling unit. The extracting unit extracts a first block at a first position of a first frame image from plural frame images constituting video data. The retrieving unit retrieves, from a retrieval region within a second frame image from among the plural frame images, a second block between which the first block has a smallest residual value, the second and first frame images having a first time length therebetween. The detecting unit detects a first motion vector between the first and second blocks. The controlling unit controls the detecting unit so that detection of the first motion vector is regulated when the second block is retrieved at a third position apart from the second position of the second frame image corresponding to the first position by a first threshold or more.

A recording/reproduction apparatus is capable of effectively and efficiently making use of a large-quantity information signal recorded onto a recording medium and efficiently utilizing the recording medium for recording the information signal. In a process to record a video signal onto the recording medium 8, a video classification process unit 5 employed in the recording/reproduction apparatus recognizes similar pictures of the video signal, classifies pictures of the signal into similar-picture segments each including similar pictures and classifies the similar-picture segments into groups each including similar-picture segments resembling each other. Then, the recording/reproduction apparatus displays a picture as a thumbnail picture for each of the similar-picture segments on a classification display unit 19. By viewing a tabular display of such thumbnail pictures, contents of the video signal recorded on the recording medium 8 can be grasped effectively and with a high degree of efficiency.

To easily reproduce data even in variable speed reproduction mode as with normal reproduction mode. Data read from a magnetic tape 1 is supplied to a reproduction equalizing portion 4 through a reproducing amplifier 3. The reproduction equalizing portion 4 trims wave shape and supplies the resultant signal to a data determining comparator 5. The data determining comparator 5 digitizes the input signal. The digitized data is supplied to a reproduction clock extracting portion 7. The reproduction clock extracting portion 7 extracts a reproduction clock. The extracted clock is supplied to a reproduction data strobe portion 6. The reproduction data strobe portion 6 supplies the digitized data to an error correcting portion 8 in synchronization with the reproduction clock. The error correcting portion 8 generates an error correction flag, an interpolation flag, and so forth. A reproduction signal processing portion 10 and a memory 9 process signals and output a sound signal through a D/A converting portion 11.
摘要:
Data reproducing apparatus for reproducing data that is recorded with a selected one of at least two different recording densities such that the played back data may exhibit different frequency characteristics, depending upon the recording density. The played back data is supplied to a selected one of plural equalizer circuits whose respective equalizing characteristics match the frequency characteristics of the played back data, thereby reducing the bit error rate of the played back data, regardless of the particular recording density with which that data had been recorded.
摘要:
In a digital data reproducing apparatus for demodulating digital data recorded on a magnetic medium with either a first or second record modulation mode, such mode is detected by identifying the frequency of a recovered clock signal derived from the digital data by a clock recovery circuit, and an appropriate demodulation circuit for the recording mode is then selected to demodulate the reproduced digital data.
