The pictogram area 1101, the information display area 1102, and the soft keys 1104 to 1106 are displayed when the control unit 350 transfers an image in which characters are expanded to the frame memory 365.
The image display area 1103 is displayed on the display device 160 by transferring the digital broadcast image decoded by the decoding unit 314 to the frame memory 365.

Next, the screen stop function during viewing will be described.
FIG. 8 shows an example of screen transition when the screen stop function is used.
A screen 701 shows a state where a digital broadcast is being viewed. When a broadcast operation is performed while receiving a broadcast, that is, when the transmission key of the key unit 180 is pressed on the digital broadcast viewing screen, the broadcast video at the timing when the broadcast operation is performed is stopped. In other words, the screen displayed on the display device 160 at that time is stationary, and an input area for inputting information on the destination is displayed. In this embodiment, a transition is made to the display state of the telephone number input screen (screen 702).
On the telephone number input screen, numbers are sequentially input by numerical key input and displayed in the number input area 70A (screen 703).
Thus, by displaying the still image and the input telephone number at the same time, it is possible to prevent an error in inputting the telephone number by the user.
Moreover, while displaying a still image, it is preferable to output audio in synchronization with (synchronously with) broadcast. Thus, after the broadcast video is stopped, the user can notice even if other contacts or addresses are introduced in the program.

  On the telephone number input screen (screen 702), the soft keys 1104, 1105, and 1106 change to “registration”, “outgoing”, and “menu”, respectively. When a key 181 (soft key 1104, that is, registration) is pressed, the display changes to the display state of the address book registration screen (screen 704), and the entered telephone number can be registered in the address book. Further, when the key 183 (FIG. 3, soft key 1105, call origination in this case) or the call key is pressed on the telephone number input screen (screen 702), the screen changes to the call origination screen (screen 705). Calling protocol processing is performed by 120, and a telephone call (calling) is performed. In addition, in the telephone number input screen (screen 703), when the key 183 (FIG. 3, soft key 1105, call in this case) or the call key is further pressed, the screen changes to the call screen (screen 705) and the control unit 350 In addition, the wireless communication unit 120 performs outgoing call protocol processing, and makes outgoing calls (calls).

When the other party answers the call, the screen transitions to the state of the in-call screen (screen 706), and the call becomes possible.
By displaying the screen on the display unit 160 during a call, the display unit 160 can confirm the content displayed on the screen during the call. In this example, in addition to the telephone number, the price of the product, the product number, the product name, and the image can be confirmed.

When the call is finished, the state transits to the state of the call end screen 707, and the call time taken for the call is displayed.
The end-call screen automatically returns to the watching screen (screen 701) after a predetermined time, for example, 10 seconds later. This process is performed by the control unit 350. The viewing screen (screen 701) may be restored by pressing the end key.

  Next, a method for realizing the processing contents described above will be described with reference to the flowchart of FIG.

Steps 1 and 2 : When the control unit 350 detects that the user has pressed the transmission key of the key unit 180 while viewing the digital broadcast, the control unit 350 writes the image to the frame memory 365 to the decoding unit 314. Give instructions to ban. Thereby, the image display area 1103 on the display device 160 does not change when the still image of the digital broadcast image displayed at that time is displayed.

Step 3 : Subsequently, the control unit 350 performs screen transition processing of the screens 701 to 707 such as telephone number input, but during this time, writing to the area corresponding to the image display area 1103 in the frame memory 365 is not performed. For this reason, during the screen transition of the screens 701 to 707, when the user presses the call key, the still screen displayed on the display device 160 is still displayed (becomes a frozen state).
Moreover, while displaying a still image, it is preferable to output audio in synchronization with (synchronously with) broadcast. Thus, after the broadcast video is stopped, the user can notice even if other contacts or addresses are introduced in the program.

  As described above, according to communication apparatus 300 with a broadcast receiving function according to an embodiment of the present invention, a user makes a call to a telephone number, URL, mail address, etc. in a broadcast program displayed on the communication apparatus. When performing outgoing operations (including transmission operations and access operations) and input operations for access, the broadcast video screen displayed at that time is frozen (freezed), and the input is performed with the still screen displayed. By presenting the screen to the user, the user can input while looking at the telephone number, URL, mail address, etc. displayed on the screen, saving time and memory, and reducing mistakes.

In the above-described embodiment, an example in which a still image is displayed without writing in an area corresponding to the image display unit in the frame memory 365 has been described. However, the image display unit in the frame memory 365 once corresponds to the image display unit. The area information is temporarily stored (copied) in the RAM 353 in the control unit 350, and subjected to appropriate image processing such as image reduction and image enhancement by the processing of the CPU 351 as necessary, and then stored in the frame memory 365. It may be transferred and displayed on a telephone number input screen or the like.
As a result, when the content read from the frame memory 365 is displayed on the display device 160, the content subjected to appropriate image processing such as image reduction or image enhancement is displayed.

In the above-described embodiment, the telephone number input screen has been described. However, this is also applicable to the input of an e-mail address, the input of a web page address, the input of a memo pad, etc. while still images are displayed. It may be.
Therefore, the communication device of the present invention is not limited to application to a mobile phone device.

  In addition, since the transmission operation is intuitively easy to use, the transmission operation is described as an example. However, when an operation for stopping the broadcast video is performed while receiving and viewing a broadcast, the operation is performed. When the key input is made in this state, information corresponding to the input is displayed, and when a transmission operation is performed, the broadcast video at the timing when the call is performed is displayed based on the input information. This also includes an operation for performing a transmission operation.

Other application examples include the following.
Since there are many cases where the history entered and sent, the sent history and the accessed history are not registered in the information stored in the communication device such as the phone book, the newly sent history, sent history, accessed history When confirming, only the date, time and information entered are displayed.
Therefore, when the above-described still image is used for making a call, sending an e-mail, accessing a WEB page, etc., it is possible to perform control so that the still image is associated with this history and stored in a memory (storage means). preferable. As a result, when displaying to confirm the history, a still image is also displayed (may be displayed as necessary), so it is easy to grasp the situation at that time, and the usability of the device is improved. improves.
