A recording/reproducing apparatus for recording as a QuickTime file a photographed motion image on a disc-like recording medium having plural recording areas different in characteristic. The plural areas include a first area guaranteeing a quick access speed and a second area which ensures a slower access speed than the first area. The recording/reproducing apparatus records a 'movie' portion constituting the QuickTime file in the first area and a 'media data' portion in the QuickTime file format in the second area.

Recording apparatus using disc-like recording medium

An image processing apparatus for inputting a moving image file containing moving image data representing a series of moving images, and still image data of a plurality of pictures related to the moving image data, selecting representative still image data from the still image data of the plurality of pictures of the inputted moving image file, recording identification information for identifying the selected representative still image data in the moving image file.

Image data containing the face image of a person is retrieved from a plurality of images, the retrieved image data is displayed, face image data, which is for image retrieval, is extracted from the displayed image data, and the extracted face image data is registered as reference face image data. Specified reference face image data in the registered reference face image data is designated and image data that contains the reference face image data is retrieved.

Image retrieval apparatus and method, and image display apparatus and method thereof

An image coding apparatus comprises a divider for dividing an image into a plurality of coding blocks overlapped to each other, and a coder for coding them for each of the coding blocks divided by the divider.

Image coding apparatus

An apparatus for recording video data by forming many tracks on a recording medium and/or for reproducing the video data from the tracks is provided with a memory which is arranged to have recording video data or reproduced video data supplied thereto. The apparatus detects the picture change-over portion of the video data obtained within the tracks and controls, in accordance with the detected position, an offset degree between the writing and reading addresses of the memory.

Video data recording and/or reproducing apparatus

In equalizing a reproduced signal with an equalizer having a variable equalizing characteristic, a decision as to whether or not the equalizing characteristic is to be varied is made by using the reproduced signal. For example, the frequency of performing an equalizing characteristic varying action is controlled according to an error rate in the reproduced signal. By virtue of this control, the equalizing characteristic can be quickly optimized in the event of a high error rate and, in a case where the error rate is low, the equalizing process can be stably carried out. Further, the equalizing characteristic is arranged to be varied while the level of the reproduced signal is in the neighborhood of a predetermined level, so that the equalizing characteristic can be optimized for such a signal that is most vulnerable to an adverse effect of the varying of the equalizing characteristic.

A signal processing apparatus for performing maximum likelihood decoding using one of a partial response PR(1,1) scheme and a partial response PR(1,0,1) scheme, has a maximum likelihood decoding device which includes a comparison circuit for comparing a branch metric difference supplied from an external circuit and a held past metric difference, a holding circuit for holding, as a new metric difference, one of the branch metric difference supplied from the external circuit and the held past metric difference on the basis of a comparison output from the comparison circuit, and a deciding circuit for deciding decoded data on the basis of the comparison output from the comparison circuit.

Signal processing apparatus

A circuit is provided for emphasizing or suppressing both a frequency corresponding to an upper sideband and a frequency corresponding to a lower sideband with respect to a frequency corresponding to the carrier of a frequency-modulated signal in equalizing the frequency-modulated signal reproduced from the recording medium. With this arrangement, it is possible to effectively compensate for the nonlinearity of a magnetic recording and reproducing system even in the case of a wide deviation. Also, the envelope levels of the portions of a frequency-modulated signal which are formed by frequency-modulating portions of a signal whose levels differ from each other, are extracted to adjust the equalizing characteristics of the equalizing circuit in accordance with the difference between the levels, whereby variations in the characteristics of a reproduction equalizing circuit due to variations with time can be appropriately compensated for.
