Abstract

This invention has as its object to record audio data by a simple operation upon recording the audio data as an operation sound or startup sound of an image sensing apparatus such as a digital camera or the like. To this end, upon recording audio data, since a startup sound, operation sound, shutter sound, and self-timer sound are set as purposes of audio data to be recorded, an audio recording time is set by selecting a desired one of these purposes. After the audio recording time is set, when audio recording is started by a user'"'"'s intention, audio recording is executed for the set time, and other operations such as an audio recording stop operation and the like are inhibited during this interval. Hence, audio recording is executed until the set audio recording time elapses.

Claims

1. An audio processor comprising:

an audio recording time setting device adapted to set an audio recording time;

an audio recording start reception device adapted to receive an audio recording start instruction; and

an audio recording device adapted to execute audio recording until the set audio recording time elapses, upon reception of the audio recording start instruction.

2. The processor according to claim 1, further comprising a reproduction device adapted to reproduce recorded audio data.

3. The processor according to claim 1, wherein audio recording times are set in advance in correspondence with a plurality of purposes of audio data to be recorded, and the audio recording time is set by selecting a desired purpose.

4. The processor according to claim 1, wherein said audio processor is provided to an image sensing apparatus which can record a sensed moving image on a recording medium, can reproduce and display the recorded moving image, and comprises a microphone and loudspeaker.

5. The processor according to claim 4, wherein at least some of a startup sound, operation sound, shutter sound, and self-timer sound are set as a plurality of purposes of audio data to be recorded, audio recording times are set in advance in correspondence with the plurality of purposes, and the audio recording time is set by selecting a desired purpose.

6. The processor according to claim 4, wherein the audio recording time which is set in advance in correspondence with the purpose of audio data is displayed on a display unit of the image sensing apparatus.

7. An audio processing method comprising:

an audio recording time setting step of setting an audio recording time;

an audio recording start reception step of receiving an audio recording start instruction; and

an audio recording step of executing audio recording until the set audio recording time elapses, upon reception of the audio recording start instruction.

8. A computer program for making a computer execute:

an audio recording time setting process for setting an audio recording time;

an audio recording start reception process for receiving an audio recording start instruction; and

an audio recording process for executing audio recording until the set audio recording time elapses, upon reception of the audio recording start instruction.

9. A computer readable storage medium storing a computer program of claim 8.
