Abstract

<P>PROBLEM TO BE SOLVED: To enable image data to be reproduced even if a digital still camera is connected to a headphone to be an audio mode. <P>SOLUTION: A digital camera which can reproduce image data and voice data recorded in a memory card 9 is provided with a voice output terminal 13 for connecting an earphone or headphone, a detecting portion 14 for detecting a connection presence/absence of the earphone or headphone to the voice output terminal 13, and a system controller 6. When the detecting portion 14 detects the connection of the earphone or headphone to the voice output terminal 13, the system controller 6 makes the digital sill camera reproduce only the voice data recorded in the memory card 9. <P>COPYRIGHT: (C)2004,JPO&NCIPI

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a digital still camera having an audio playback function in addition to an image playback function.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, there is a “digital camera” having an audio reproduction function in addition to an image reproduction function (see Patent Document 1). The digital camera has an audio mode for reproducing sound and a camera mode for photographing, recording, and reproducing an image. When headphones are connected to the digital camera body, the digital camera enters the audio mode, and the sound reproduction has priority over image photographing.

[Problems to be solved by the invention]
However, the above-mentioned "digital camera" has a problem that the audio mode is set when headphones are connected, and the image data cannot be reproduced as it is. In a conventional digital still camera capable of reproducing image data and audio data recorded on a memory card, when a reproduction mode is selected, image data and audio data are reproduced without distinction. In this case, if the user wants to reproduce the audio data, it takes time to select the audio data to be reproduced because the number of image data is overwhelmingly larger than the audio data in the normal use condition of the digital still camera It is not convenient.
Therefore, according to the present invention, if an earphone or a headphone is connected in the playback mode, it is determined that the user wants to play back the audio data, and only the audio data is reproduced, so that the user can easily select the audio data to be reproduced. It is an object of the present invention to provide a digital still camera capable of performing such operations.
[0005]
[Means for Solving the Problems]
In order to solve the above problem, an invention according to claim 1 is an audio output terminal for connecting an earphone or a headphone in a digital still camera capable of reproducing image data and audio data recorded on a memory card. A detecting unit for detecting whether or not an earphone or a headphone is connected to the audio output terminal, and reproducing only the audio data recorded on the memory card when the detecting unit detects the connection of the earphone or the headphone. And a system control unit for controlling the operation.
[0006]
According to a second aspect of the present invention, in the first aspect of the present invention, even when the detection unit detects the connection of an earphone or a headphone, if there is an input for reproducing the image data by operating the operation unit, the image data is prioritized. It is characterized by having a system control unit that controls to play back.
[0007]
According to a third aspect of the present invention, in the first aspect of the present invention, when the detection unit detects the connection of an earphone or a headphone, and when no audio data is recorded on the memory card, the fact is indicated on the LCD. And a system control unit for displaying the information.
[0008]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, embodiments of the present invention will be described with reference to the drawings.
FIG. 1 is a block diagram showing a schematic configuration of a digital still camera according to the present invention. In the figure, an imaging unit 1 converts an image of a subject into an analog image signal. The A / D converter 2 converts an analog image signal sent from the imaging unit 1 into digital image data. The digital signal processing unit 3 divides the digital image data input from the A / D converter 2 into a color difference component and a luminance component, and performs necessary various processes, a correction process, and a pre-process for image compression / decompression. The image compression / decompression unit 4 performs processes such as orthogonal transformation and Huffman encoding / decoding for JPEG-compliant image compression / decompression. The memory card 9 is a detachable recording medium for recording image data compressed by the image compression / decompression unit 4 via the memory card I / F 8.
[0009]
The system control unit 6 performs system control, power control, memory control, and the like of the entire camera. The operation unit 7 includes a reproduction condition setting unit, a power switch, a release, a photographing condition setting unit, and the like. The LCD 10 is for confirming an image to be photographed or a recorded image. The audio output terminal 13 is for confirming audio data reproduced through the audio reproduction circuit 12, and can be connected to an earphone or headphones (not shown). The detection unit 14 detects whether an earphone or headphones is connected to the audio output terminal 13 and sends the detection result to the system control unit 6. The power supply circuit 11 supplies power to each unit according to an instruction from the system control unit 6.
[0010]
Next, the operation of the digital still camera according to the present invention will be described. When an earphone or headphones is connected to the audio output terminal 13 when the digital still camera is in the reproduction mode, a detection result is sent from the detection unit 14 to the system control unit 6, and the system control unit 6 reproduces only audio data. To control the digital still camera. At this time, if there is an operation input for reproducing the image data by operating the operation unit 7, the image data is reproduced. If no voice data is recorded on the memory card 9, a message such as "no voice data" is displayed on the LCD 10 to notify the user.
[0011]
【The invention's effect】
As described above, according to the present invention, if earphones or headphones are connected to the camera body, only the audio data is reproduced, so that the audio data to be reproduced can be quickly selected. In addition, even when audio data is being reproduced, if the user wants to reproduce the image data, the image data is preferentially reproduced by inputting the reproduction of the image data by operating the operation unit. Furthermore, even if the camera is connected to earphones or headphones and the audio playback mode is set, if there is no audio data on the memory card and playback is not possible, the fact is displayed on the LCD, so there is no need to mistake for failure. Can be.
