The storage device 14 has a digital image data buffer for temporarily storing image data during transmission / reception, an adapter connection state management flag for checking the connection state of the adapter, a display buffer for performing various displays, and the like.

The adapter detection circuit 19 detects the connection state of the adapter, that is, the connection / non-connection of the adapter.

The control unit 10 includes a read-only storage device 13
By reading the control program, various controls and data operations of the mobile phone device are performed.

The display unit 15 performs display according to a control program and a display table in the read-only storage device 13 for performing various setting states, confirmation, and the like.

The wireless section 16 transmits various data stored in the storage device 14 to a wireless line, or receives various data from the wireless line, and stores the data in the storage device 14.

FIG. 1 is a flowchart of a transmission method in the digital portable telephone device according to the present invention, and shows a process from a waiting state of an incoming signal to completion of image data transmission.

Next, the operation of the digital portable telephone device of this embodiment will be described with reference to FIGS.

When the adapter 2 is connected in the incoming signal waiting state (step 31), the connection of the adapter is detected by the adapter detection circuit 19 and transmitted to the control unit 10.
Then, the control unit 10 rewrites the adapter connection state flag in the storage device 14 to “ON” according to the control program in the read-only storage device 13. Next, by starting the setting of the image data transfer mode (step 32) from the key operation unit 12, the control unit 10 checks the state of the adapter connection state management flag in the storage device 14 (step 3).
3) If the flag is “ON: the adapter is connected”, an image data input mode selection screen is displayed on the display unit 15 according to the display table in the read-only storage device 13, and input from the key operation unit 12 is waited. The state is reached (step 34).

Here, if the adapter connection status flag in the storage device 14 is "OFF", that is, if the adapter is not connected (step 33), the control unit 10 enters the incoming signal waiting state (step 31) according to the control program. Return and wait for the next key operation or incoming signal input (step 3
3).

After the image data input mode selection screen is displayed (step 34), when the digital image data input mode is selected (step 35), the digital image transfer mode is set, and the digital image data input wait state is set (step 36). Thereafter, the image is converted into digital data by the adapter 2 and input from the adapter via the digital video signal input / output terminal 11 (step 37).

When the digital image data is input, the control section 10 performs data error detection and error correction of the digital image data in accordance with the control program stored in the read-only storage device 12 while controlling the digital data stored in the storage device 14. Store in the image data buffer (step 3
8).

When the input of the digital image data is completed, a reception completion message is displayed on the display unit 15 according to the display table in the read-only storage device 13.

After displaying the reception completion message, the control unit 10 displays a transmission confirmation mode screen on the display unit 15 according to the control program and the display table, and enters the transmission confirmation mode.
Waiting for input from the key operation unit 12 (step 3
9).

Here, when the enter key of the key operation unit 12 is pressed, the digital image data in the storage device 14 is deleted.
The data is loaded from the digital image data buffer in the storage device 14 according to the control program, and the radio unit 16 and the antenna 1 are loaded.
7, and transmission to the base station via the wireless line 18 (step 40).

When the transmission is completed, a transmission completion message is displayed on the display unit 15, and the process returns to the image data input waiting state (step 36).

When the end key of the key operation section 12 is pressed in the transmission confirmation mode, the digital image data in the digital image data buffer in the storage device 14 is erased from the storage device 14 and the digital image data input wait state is returned (see FIG. Step 36).

In the above embodiment, the method of inputting digital image data from the adapter to the mobile phone and transmitting the digital image data by the digital mobile phone has been described.
To the adapter 2 and receive it on the adapter side.

Note that the following modification of the digital portable telephone device shown in FIG. 2 is also possible. The key operation unit 12 may be operated by connecting to an external computer, an adapter, or the like. The storage device 14 generally includes a RAM
(Read Only Memory), but a rewritable EEPROM (Electrically Only).
Erasable Programmable Re
ad-only memory) or a flash memory may be used. An adapter connection state flag is not provided, and the detection signal from the adapter
May be directly input to the input terminal, and the control unit 10 may directly detect connection / non-connection of the adapter using only the detection signal.

[0033]

According to the present invention, it is easy to detect an error at the time of inputting / outputting data, so that deterioration of image data can be easily prevented, and input / output of high-quality digital image data can be performed.

Further, since image data can be transferred by an adapter or a digital mobile phone, when image data is not transferred, the digital mobile phone can be used alone.

When no adapter is connected,
There is no possibility of accidentally setting the image transfer mode.
