In other words, when the image output unit 9 is opened with the cover directly under the image output unit 9, the video tape 102 is mounted in the space thereunder.

3A to 3C are block diagrams in which an LCD player digital still camera according to an embodiment of the present invention is applied.

As shown in FIG. 3A, the camera device A of the LCD player detachable digital still camera according to the embodiment of the present invention is independently connected to a camcorder CAM or video V1. Can be used.

As shown in (b) and (c) of FIG. 3, the image display device C of the LCD player detachable digital still camera according to the embodiment of the present invention is a television monitor M or another image. It may be used in connection with the display device P1.

1 to 3, an LCD player detachable digital still camera according to an embodiment of the present invention will be described.

The user holds the camera device A in his hand to take a picture, and then points it toward the subject.

Then, the light reflected and incident on the subject is incident on the lens group L1, and the lens group 1 forms the incident light on the CCD unit 3.

The CCD unit 3 drives in accordance with the drive signal of the first microcomputer 2 to convert the light formed by the lens group 1 into an electrical signal and output the converted signal to the signal processor 4.

The signal processing unit 4 converts the signal input from the CCD unit 3 into a digital image signal, and outputs the converted digital image signal to the outside and to the first storage unit 5.

Here, one side of the camera device (A) is connected to one end of the transmission unit (B), and the digital image signal output from the signal processing unit (4) converts the digital image signal to the image through the transmission unit (B). Is sent to a device that can represent it.

The transmitter B in this invention transmits the digital video signal to the image display device C shown in Figs.

The image display device C has an input / output unit 6 including an image input terminal c1 on one side thereof and is connected to the other end of the transfer unit B.

Thus, the digital image signal transmitted through the transmission unit B is input to the image display unit 9 according to the control signal of the second microcomputer 8 to appear as an LCD image.

When the image of the subject appears on the LCD image as described above, the user moves the camera apparatus A up, down, left, or right while viewing the image of the subject through the image display unit 9 or not. Operate the mounted zoom switch S3 to set the desired subject composition.

In the above, when the user presses the tele switch S32 of the zooming switch S3, an image of an increasingly narrow subject area appears on the image display unit 9 of the image display device C, and the user zooms in the zooming switch S3. When the wide switch S31 is pressed, the image display unit 9 displays an image of an increasingly wider subject area.

When the subject composition is set by the above operation, the user presses the release switch S1 attached to the camera device A for shooting.

Then, the first microcomputer 2 detects an operation signal of the release switch S1 and outputs a control signal to the first storage unit 5 to store the digital image signal being transmitted.

The first storage unit 5 is driven according to a control signal output from the first microcomputer 2 so that the digital image signal is stored in the inserted first storage unit 5.

In addition, the first microcomputer 2 transmits a control signal to the second microcomputer 8 through the transmission unit B.

Then, the second microcomputer 8 outputs a control signal to the second storage unit 10 according to the input control signal of the first microcomputer 2.

The second storage unit 10 also stores the digital image signal in the second memory card 101 inserted as in the first storage unit 5.

Therefore, the digital image signals stored in the first memory card 51 of the camera device A and the second memory card 101 of the image display device C are the same.

Since the first storage unit 5 and the second memory card 101 may be used in a personal computer or a device capable of displaying a digital image signal as an image, it is convenient to check the information of the photographed subject.

As shown in FIG. 3, the use of the two memory devices as described above allows the camera device a and the image display device c to operate independently, such as the video V1 or the camcorder CAM, or the like. Since it can be used in connection with another image display device P1, it is for storing the photographed subject information for the case of being used in connection with each device.

The above description has described a process of photographing a subject without movement by one frame.

The following description describes a process of continuously photographing a moving subject, that is, photographing a moving image.

As described above, when the user points the camera device A toward the subject side, the image of the subject appears on the image display unit 9 of the image display apparatus C. FIG.

Then, the user sets the composition of the subject by manipulating the zoom switch S3 or by moving the camera device A while looking at the displayed image.

In the above state, the user presses the recording button b2 of the recording button section 7 to capture the moving picture.

Then, the second microcomputer 8 detects an operation signal of the recording button b2 and outputs a control signal to the second storage unit 10.

The second storage unit 10 stores the digital video signal corresponding to the image currently displayed on the image display unit 9 in the video tape 102 according to a control signal output from the second microcomputer 8. The tape 102 is driven to record digital image information.

In the recording process, the user may connect the microphone to the microphone terminal c4 of the input / output unit 6 to record desired contents on the video tape 102.

The video tape 102 is mounted under the image display unit 9.

Therefore, the user can open the image display section 9 to insert the video tape 102 to mount or to remove it.

The user presses the stop button b3 if the user wants to stop recording while shooting a video of the subject.

Then, the second microcomputer 8 detects an operation signal of the stop button b3, and accordingly, the second storage unit 10 stops driving of the video tape 102 and recording of digital image information. Outputs a control signal.

When the user presses the play button b1 to check the stored video while the moving picture is stored in the video tape 102 by operating the recording button b2 and the stop button b3 as described above, the second micom (8) detects the operation of the play button (b1).

Then, the second microcomputer 8 outputs a control signal corresponding to the second storage unit 10 and the image display unit 9, and the second storage unit 10 drives the video tape 102. And store the stored digital video signal to the image display unit 9.

The image display unit 9 displays an image corresponding to the input digital video signal on the LCD screen.

Here, the user can operate the forward and backward direction buttons b4 and b5 so that an image of a desired portion of the image recorded on the video tape 102 is displayed on the image display unit 9.

In addition, the user may connect the earphone to the earphone terminal c3 of the input / output unit 6 to listen to the recorded voice information while viewing the recorded image.

Therefore, the present invention can store and reproduce not only still images but also moving images, and can record audio.

In the present invention performing the above function, as shown in (a) of FIG. 3, the camera device A may be connected to a camcorder CAM or video V1 and used as a function of video shooting. As shown in (b) of FIG. 3, the image display device (C) is connected to the television monitor (M) to allow viewing of recorded images without a device such as a video or a camcorder, and also to display another image as shown in (c) of FIG. Connected to the apparatus P1, it is possible to exchange recorded image data or to copy a video tape.

The present invention is small in size and portable by allowing a camera device having a camera function of photographing a subject and an LCD player displaying a screen of recorded image information to be independently separated, and performing a function of a digital still camera by connecting each of them with a cable. It is convenient to do, video recording is possible, and each of the separate camera device and LCD player can be used in connection with the peripheral device, which not only expands its use but also expands the function.
