Abstract:
1. A digital camera comprising: a mode selection device which selects a desired operation mode from a plurality of operation modes, said plurality of operation modes include a shooting mode, an image reproducing mode, an audio recording mode and an audio reproducing mode; a recording device on which image data and audio data are recorded as a predetermined file format; an image sensor; a monitor; an image processing device for recording/reproducing an image, wherein when the mode selection device selects the shooting mode, the image processing device performs predetermined signal processes for image data outputted from the image sensor and compresses the image data in a predetermined file format, and the compressed image data is recorded on the recording device, and when the mode selection device selects the image reproducing mode, the image processing device decompresses the image file data recorded on the recording device to a decompressed signal, and the decompressed signal is outputted to the monitor; a microphone; a speaker; an audio processing device for recording/reproducing audio which is operated at a lower voltage than said image processing device, wherein when the mode selection device selects the audio recording mode, the audio processing device converts an audio signal inputted through the microphone into a digital signal in a predetermined file format, and the digital signal is recorded on the recording device as an audio file, and when the mode selection device selects the audio reproducing mode, the audio processing device converts the audio file recorded on the recording device into an audio signal, and the audio signal is outputted as audio through the speaker; a power supply device which generates operating voltages peculiar to the image sensor and the monitor respectively and supplies the operating voltages to the image sensor and the monitor respectively, and which generates a first operating voltage and a second operating voltage which is lower than said first operating voltage; and a voltage control device which supplies the first operating voltage to the image processing device from the power supply device in case of the shooting mode or the image reproducing mode and supplies the second operating voltage to the audio processing device from the power supply device in case of the audio recording mode or the audio reproducing mode.
