As shown in FIG. 1, the camera according to the present embodiment is divided into a photographing device 101 for photographing image and sound information and a recording device 112 for recording image and sound information on an optical disk 113.
[0011]
First, a technique in which the image capturing apparatus 101 captures image and audio information and transmits the information to the recording apparatus 112 will be described with reference to FIG.
[0012]
In the photographing device 101, a CCD 102 (Charge Coupled Diode) converts an optical signal of image information obtained through a lens into an electric signal, and an image digitizing circuit 103 converts an analog electric signal converted by the CCD 102 into digital image information. After conversion, the image compression circuit 104 compresses the digitized image information by MPEG (Moving Picture Experts Group), JPEG (Joint Photographic Coding Experts Group), or the like. The audio digitizing circuit 105 amplifies the audio signal from the microphone 106 and converts it into a digital audio signal, and the audio compression circuit 107 compresses the digitized audio signal using, for example, MPEG. The compressed image information and audio information are multiplexed by the demultiplexing circuit 108.
[0013]

Next, the control circuit 115 separates the identification information of the photographing device 101 added to the image / audio information from the image / audio information stored in the buffer 125.
[0017]
Next, in step S202, the control circuit 115 compares the identification information of the separated imaging device 101 with the identification information of the imaging device stored in the control circuit 115, and if the identification information matches, the processing proceeds. Controls the optical disk recording / reproducing circuit 117 so that the image / audio information is recorded on the optical disk 113 in step S203. The optical disk recording / reproducing circuit 117 records the video / audio information on the optical disk 113 in accordance with an instruction from the control circuit 115.
[0018]
In step S202, when the identification information of the separated imaging device 101 does not match the identification information of the imaging device stored in the control circuit 115, the control circuit 115 stores the image / audio information in the recording medium. The processing is terminated without recording the information in.
[0019]
As described above, the recording device 112 can reduce the possibility of erroneously recording the image / audio information transmitted from a device other than the imaging device 101 of the stored identification information on the optical disk 113.
[0020]
When the received video and audio information is reproduced by the LCD 123 (Liquid Crystal Display) and the speaker 124, the control circuit 115 outputs the video and audio information to the demultiplexing circuit 118. The demultiplexing circuit 118 separates the image and audio information, outputs the separated image information to the image expansion circuit 119, and outputs the separated audio information to the audio expansion circuit 120. The image expansion circuit 119 expands the image information output from the demultiplexing circuit 118 and outputs the image information to the image analog conversion circuit 121. The audio expansion circuit 120 expands the audio information output from the demultiplexing circuit 118 and outputs the expanded audio information to the audio analog conversion circuit 122. The image analog conversion circuit 121 converts the digitized image information into an analog signal, converts the format into NTSC or the like, and outputs it to the LCD 123 or an external image display device. On the other hand, the audio analog circuit 122 converts the digitized audio information into an analog signal, and outputs the analog signal to the speaker 124 or an external audio output device.
