摘要:
An operational information obtaining section of a music reproduction device obtains operational information which corresponds to a user's operation and represents an instruction on an action of a reproduction section for reproducing data of a musical composition. A selection condition calculation section changes, during the musical composition being reproduced by the reproduction section, relative merits of attribute information relating to the data of the musical composition in accordance with details of the operational information obtained by the operational information obtaining section, and then calculates, based on the relative merits of the attribute information, a condition for selecting the data of the musical composition to be reproduced by the reproduction section. The relative merits of the attribute information, which is information relating to the data of the musical composition, is changed in accordance with the user's operational information, and selection is performed in accordance with the relative merits of the attribute information, whereby it is possible, with the user's simple operation, to reproduce only the musical composition which is desired to be listened to.

The present invention provides a music search system for conducting music search, which allows the user to easily listen to music matched to situation. The music search system includes a music data storage section, a location acquisition section, a parameter converting section, a music search section, and a reproducing section. The music data storage section stores a plurality of pieces of music data so as to be associated with a corresponding one of music parameters. The location acquisition section acquires a situation parameter. The parameter converting section converts the situation parameter acquired by the location acquisition section into the music parameter. The music search section uses the music parameter resulted from conversion by the parameter converting section to search through the plurality of pieces of music data stored in the music storage section and selects a piece of music to be reproduced. The reproducing section reproduces the piece of music selected by the music search section.

The present invention implements a method and an apparatus for retrieving a sound data desired by the user on the basis of its subjective impression over the sound data. The subjective impression on the desired sound data is entered by the user and converted to a numerical value. A target sound impression value which is a numerical form of the impression on the sound data is calculated from the numerical value. The target sound impression value is then used as a retrieving key for accessing a sound database where the audio signal and the sound features of a plurality of the sound data are stored. This allows the desired sound data to be retrieved on the basis of the subjective impression of the user on the sound data.

An audio reproducing apparatus comprises: audio decoding means for decoding an input audio signal frame by frame; data expanding/compressing means for subjecting data in a decoded frame to time-scale modification process; a frame sequence table which contains a sequence determined according to a given speed rate in which respective frames are expanded/compressed; frame counting means for counting the number of frames of the input audio signal; and data expansion/compression control means for instructing the dalta expanding/compressing means to subject the frame to one of time-scale compression process, time-scale expansion process, and process without time-scale modification process, with reference to the frame sequence table based on a count value output from the frame counting means, the data expanding/compressing means subjecting the audio signal to time-scale modification process in accordance with an instruction signal from the data expansion/compression control means.
摘要:
A data input unit is configured to receive an input image, depth data and a shooting parameter. A parameter input unit receives a transformation parameter as a parameter on projective transformation of a three-dimensional model, a transformed image generating unit that generate a transformed image by performing projective transformation based on the transformation parameter in the three-dimensional model obtained from the input image, the depth data, and the shooting parameter. A blank area detecting unit detects a blank area in the transformed image, the blank area being a group of blank pixels having no corresponding pixel in the input image, and an output unit is configured to output the transformed image in the case where a blank value indicating size of the blank area is smaller than or equal to a threshold value.
