FIG. 2 is a block diagram showing the configuration of the foldable communication terminal apparatus according to the present invention. For example, IS-95 (I
nterim Standard 95) based CDMA (Code Division
It shows a case where the present invention is applied to a mobile terminal device of a multiple access (mobile access) type mobile phone. The same components as those in FIG. 1 are denoted by the same reference numerals, and description thereof will be omitted. However, the communication method is not limited to the CDMA method, but may be a PDC (Personal Digital Cellular) or a PHS (Pers
onal Handyphone System).

As is apparent from FIG. 2, the foldable communication terminal device 1 includes an antenna 15, a transmission / reception unit 21, a modulation / demodulation unit (that is, including a baseband processing unit) 22, an audio processing unit 24, a microphone 9, Receiver 16, control unit 20, main display unit 2, sub display unit 18, camera unit 25, camera I / F
26 and an operation unit 23.

The control unit 20 includes, for example, a microprocessor, a ROM (Read Only Memory) 20a and a RAM (Rando
m Access Memory) 20b, and performs various controls according to a control program stored in the ROM 20a. Further, in the RAM 20b, information to be transmitted, received information, telephone directory data (for example, data for 999 memory dials), and the like are stored temporarily or until an erase / change operation is performed. .

The main display unit 2 and the sub display unit 18
Each corresponds to the main display 2 and the sub-display 18.

The operation unit 23 includes a flexible key 3, four contact keys 4, an e-mail key 5, an OK key 6, an end / power key 7, a ten key 8, a WEB key 11, a side key 12,
It comprises a start key 14 and an open / close detection switch 19.

In the foldable communication terminal device 1 having the above configuration, the received radio wave is received by the transmission / reception unit 21 via the antenna 15 and demodulated by the modulation / demodulation unit 22. The audio information demodulated by the modulation / demodulation unit 22 is supplied to an audio processing unit 24, and under the control of the control unit 20, a predetermined process is performed by the audio processing unit 24. And output as audio.

The received data demodulated by the modem unit 22 is supplied to the control unit 20. The received data includes control data, character data and the like (for example, the other party's telephone number), image data, and the like, and is supplied to the main display unit 2 and the sub display unit 18 as needed to be displayed as character information and image information. , Are stored in the RAM 19a. The control data of the received data includes incoming call information of the voice communication (including the telephone number of the caller) and an SMS bearer (short
It also includes data such as e-mail and character message arrival information transmitted by a method called “message bearer”.

On the other hand, the input sound is subjected to sound-electric conversion by the microphone 9, subjected to predetermined processing by the sound processing unit 24, and then supplied to the modem 22. The input information from the operation unit 23 is transmitted to the R through the control unit 20 as necessary.
The data is stored in the AM 20b and supplied to the modem 22 as transmission data. The modulation / demodulation unit 22 modulates the supplied audio signal and transmission data, and transmits the modulated signal via the transmission / reception unit 21 from the antenna 15.

The camera unit 25 is connected to the control unit 20 via a flexible cable and a camera I / F 26. When an operator operates the operation unit 23 to input various commands related to camera photography, the control unit 20 Camera I /
Send an instruction to F26. Upon receiving the shooting instruction, the camera I / F 26 outputs various control commands to the camera unit 25, and stores the imaging data obtained from the camera unit 25 in the RAM 20b. However, since the RAM 20b generally has a small capacity, a large-capacity RAM for exclusively storing imaging data may be separately provided. Naturally, the imaging data stored in the RAM 20b can be transmitted from the antenna 15 via the transmission / reception unit 21 after being modulated by the modulation / demodulation unit 22. Note that, as described above, the laser irradiation device is incorporated in the camera unit 25, and when a photographing preparation instruction is received, laser light is irradiated from a small hole provided below the lens, and further, a photographing start instruction is issued. When the laser beam is received, the irradiation of the laser beam is stopped.

FIG. 3 is a schematic diagram of a foldable communication terminal device according to the present invention.

When displaying the image data stored in the RAM 20b on the sub-display 18, the control unit 20 determines whether or not the image is being captured. Normally displayed for easy viewing by the user (see FIG. 3A). On the other hand, when a shooting preparation instruction is received during shooting, a laser beam is emitted from the laser irradiation device and the normal display shown in FIG. The image data is displayed upside down (see FIG. 3B). Furthermore,
When the photographing start instruction is received, the irradiation of the laser light is stopped, so that no trace of the red laser light remains on the actually photographed human image. FIG. 3 (C)
Shows the display state of the main display 2 at the time of shooting.

Next, the photographing operation of the foldable communication terminal device according to the present invention configured as described above will be described in detail.

FIG. 4 is a flowchart showing an image display processing subroutine of the photographing control method according to the present invention.

First, when the user of the foldable communication terminal 1 operates the end / power key 7 to turn on the power, the control unit 20 reads the control program from the ROM 20a and performs necessary initial settings. A signal is transmitted / received to / from a base station (not shown) in a predetermined procedure to perform location registration, and the apparatus enters a standby state. Then, the user operates the operation unit 23 (photographing operation or readout display operation), and the sub-display 18 is operated.
Is given an instruction to display imaging data, the control unit 20 calls this image display processing subroutine.

The control unit 20 determines in step 100 whether or not the display is during shooting (when a shooting preparation instruction is received).
If it is not a display during shooting, the process proceeds to step 104,
Normal display is performed as shown in FIG. On the other hand, if the display is during shooting, the process proceeds to step 101, where laser light is irradiated from the laser irradiation device,
As shown in FIG. 3B, the image data is displayed upside down from the normal display, and the process proceeds to step 102.

When the control section 20 receives the photographing start instruction in step 102, the control section 20 proceeds to step 103, stops the irradiation of the laser beam, and ends.

[0053]

As described above, according to the foldable communication terminal apparatus and the image display method according to the present invention, when the imaging data is displayed on the sub-display, it is easy for the user to see if the imaging data is not taken. The image is normally displayed on the screen, but it is displayed upside down when shooting, and when a shooting preparation instruction is received, a laser beam is emitted from a laser irradiation device. Is stopped, it is possible to correctly photograph and display the photographed image of the photographer himself.
