ABSTRACT:
BACKGROUND OF THE INVENTION
FIELD OF THE INVENTION
This invention relates to an apparatus for processing, recording and reproducing images and audio.
In known digital electronic cameras whose specifications conform to the still-video recording format, image and audio data is processed and recorded on a digital recording medium such as a hard disk or floppy disk.
In the conventional still-video recording format, the image data and audio data are each frequency-modulated and recorded on separate tracks. In the audio track, a field for recording the track channel number of the associated image track (video track) is provided in a control track and it is so arranged that an annotation (identifying information), regarding a specific image can be recorded at the same time.
However, the following problems are encountered in the conventional digital electronic camera of the type described above:
(1) With the still-video recording format, a video track desired to be referred to can be designated from an audio track but an associated audio track cannot be designated from a video track. Accordingly, in order to determine the relationship between audio data and image data, all tracks on a still-video floppy disk serving as the recording medium must be retrieved, all of the audio tracks must be played back and the video track desired to be referred from the audio track must be found. Since this inevitably requires an enormous amount of time, this approach involves considerable waste and is not realistic.
(2) Only one image can be referred to from an audio track. In a case where it is desired to refer to a plurality of images, therefore, one item of audio cannot be made to correspond to the plurality of images in common. Accordingly, if it is desired to annotate a plurality of images under a common concept by voice, this cannot be accomplished at one time.
(3) In order to record audio data on a recording medium, a large storage capacity is necessary. As a consequence, recording a simple annotation regarding an image on an audio track is inappropriate in terms of cost.
These problems relating to the conventional digital electronic camera arise not only in digital electronic cameras but also generally in apparatus that process audio data and image data.
SUMMARY OF THE INVENTION
Accordingly, an object of the present invention is to provide an apparatus for processing audio data and image data, in which it is possible link files in which a stored file of image data can be linked with at least a stored file of audio or character data and either file can be retrieved from the other at high speed and reproduced, and in which it is possible to readily edit and record an expression of the mutual relationship among the image, audio and text files.
Another object of the present invention is to provide an apparatus for processing audio data and image data, in which audio data or image data can be recorded upon being converted to a text format, as a result of which an annotation (identifying information) can be appended to image data using only a small amount of memory capacity.
A further object of the present invention is to provide an apparatus for processing audio data and image data, in which audio data and image data can be retrieved on the basis of a text file appended as an annotation and it is possible to use the text file as a keyword when a data base is created.
Still another object of the present invention is to provide an apparatus for processing audio data and image data, the apparatus being capable of executing processing such as recording audio data or image data upon automatically linking this data with information that has been recorded on another data base.
According to the present invention, the foregoing objects are attained by providing an apparatus for processing image data and audio data, comprising recording means for recording image data and audio data on a recording medium in associated form, designating means for designating the audio data that has been recorded on said recording medium, retrieving means for retrieving the image data associated with the designated audio data by said designating means, reproducing means for reading the retrieved image data by said retrieving means out of said recording medium and reproducing this image data, and character recognition means for performing character recognition based upon the image data, wherein registration processing is executed in such a manner that results of character recognition performed by said character recognition means can be recorded and retrieved, as a text data, in association with the image data and the audio data.
According to the present invention, the foregoing objects are attained by providing an apparatus for processing image data and audio data, comprising recording means for recording image data and audio data on a recording medium in associated form, designating means for designating the audio data that has been recorded on said recording medium, retrieving means for retrieving the image data associated with the designated audio data by said designating means, reproducing means for reading the retrieved image data by said retrieving means out of said recording medium and reproducing this image data, and audio recognition means for recognizing the audio data as audios, wherein registration processing is executed in such a manner that results of audio recognition performed by said audio recognition means can be recorded and retrieved, as a text data, in association with the image data and the audio data.
According to the present invention, the foregoing objects are attained by providing an apparatus for processing image data and audio data, comprising recording means for recording image data and audio data on a recording medium in associated form, designating means for designating the image data that has been recorded on said recording medium, retrieving means for retrieving the audio data associated with the designated image data by said designating means, reproducing means for reading the retrieved audio data by said retrieving means out of said recording medium and reproducing this audio data, and character recognition means for performing character recognition based upon the image data, wherein registration processing is executed in such a manner that results of character recognition performed by said character recognition means can be recorded and retrieved, as a text data, in association with the image data and the audio data.

According to the present invention, the foregoing objects are attained by providing an apparatus for processing image data and audio data, comprising recording means for recording image data and audio data on a recording medium in associated form, designating means for designating one item of audio data that has been recorded on said recording medium, retrieving means for retrieving, as file information, plural items of image data associated with the designated one item of audio data by said designating means, reproducing means for reading the retrieved plural items of image data by said retrieving means out of said recording medium and reproducing this image data, and character recognition means for performi
