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 for processing audio data of an effect sound in an image sensing apparatus comprising:

an audio recording time setting device adapted to set an audio recording time period of the effect sound in accordance with a desired purpose of the effect sound which corresponds to an operation status of an image sensing apparatus, wherein the audio recording time period is a time period between start of recording the effect sound and end of recording the effect sound and wherein the set audio recording time period is selected from a plurality of time periods by selecting the desired purpose of the effect sound from a plurality of desired purposes by a user, said plurality of time periods being prepared in advance in association with the desired purposes;

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

an audio recording device adapted to record audio until the set audio recording time period elapses, upon reception of the audio recording start instruction; and

a registration device adapted to register the audio data recorded by said audio recording device according to the desired purpose of the effect sound.

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

3. An audio processing method for processing audio data of an effect sound in an image sensing apparatus comprising:

setting an audio recording time period of the effect sound in accordance with a desired purpose of the effect sound which corresponds to an operation status of an image sensing apparatus, wherein the audio recording time period is a time period between start of recording the effect sound and end of recording the effect sound and wherein the set audio recording time period is selected from a plurality of time periods, by selecting the desired purpose of the effect sound from a plurality of desired purposes by a user, said plurality of time periods being prepared in advance in association with the desired purposes;

receiving an audio recording start instruction;

recording audio until the set audio recording time period elapses, upon reception of the audio recording start instruction; and

registering the audio data recorded at said recording step according to the desired purpose of the effect sound.

4. A computer program encoded on a non-transitory computer readable medium for processing audio data of an effect sound in an image sensing apparatus, the program comprising the steps of:

setting an audio recording time period of the effect sound in accordance with a desired purpose of the effect sound which corresponds to an operation status of an image sensing apparatus, wherein the audio recording time period is a time period between start of recording the effect sound and end of recording the effect sound and wherein the set audio recording time period is selected from a plurality of time periods, by selecting the desired purpose of the effect sound from a plurality of desired purposes by a user, said plurality of time periods being prepared in advance in association with the desired purposes;

receiving an audio recording start instruction;

recording audio until the set audio recording time period elapses, upon reception of the audio recording start instruction; and

registering audio data recorded at the recording step according to the desired purpose of the effect sound.

5. A non-transitory computer readable storage medium storing a computer program of claim 4.

6. An image sensing apparatus capable of recording an effect sound comprising:

an audio recording time setting device adapted to set an audio recording time period of the effect sound in accordance with a desired purpose of the effect sound which corresponds to an operation status of an image sensing apparatus;

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

an audio recording device adapted to record audio until the set audio recording time period elapses, upon reception of the audio recording start instruction;

a registration device adapted to register the audio data recorded by said audio recording device according to the desired purpose of the effect sound;

a reproduction device adapted to reproduce the recorded audio data; and

a display unit adapted to display the audio recording time period set by said audio recording time setting device,

wherein the audio recording time period is a time period between start of recording the effect sound and end of recording the effect sound,

wherein the set audio recording time period is selected from a plurality of time periods by selecting the desired purpose of the effect sound from a plurality of desired purposes by a user, said plurality of time periods being prepared in advance in association with the desired purposes, and

wherein the effect sound includes at least one of a startup sound, a shutter sound, and a self-timer sound.
