A portable terminal in which the upper housing 102 is connected to the lower housing 105 so as to be physically rotatable in the longitudinal direction and the lateral direction so as to be switched to the direction display 103b is used. A portable terminal configured to be able to switch between portrait display and landscape display by such a rotation mechanism is described in, for example, Patent Document 3.

  FIG. 2 is a block diagram of the portable terminal showing the embodiment of the present invention.

  In FIG. 2, an antenna 401 transmits and receives radio waves. The wireless transmission / reception unit 402 modulates / demodulates transmission / reception data. The data processing unit 403 processes data to be modulated and demodulated data. Audio data from the data processing unit 403 is converted from a digital signal to an analog signal by the D / A conversion unit 404 and transmitted to the speaker 405 or the receiver 406. An analog signal from the microphone 408 is converted into a digital signal by the A / D conversion unit 407 and transmitted to the data processing unit 403. Of the received data, characters other than voice and image data are sent from the data processing unit 403 to the display image data generation unit 409.

  The device state detection unit 420 detects whether the display unit is in the portrait orientation or landscape orientation. A key input unit 421 detects input information from a numeric keypad, function keys, and side keys. The control unit 418 controls the operation timing of all the blocks in accordance with the program stored in the program storage unit 419. The control unit 418 also instructs the display image data generation unit 409. A display image data generation unit 409 generates display image data from an instruction from the control unit 418 and characters or image data from the data processing unit 403, and stores the display image data in the display image data storage unit 410.

  In the conventional portable terminal, the display image data storage unit 410 and the data conversion & transmission unit 413 are directly connected. However, in the present invention, the switch 411 and the switch 412 are provided. When the switch is on the a side, the display is directly connected. In this case, it is connected to the data conversion & transmission unit 413 via the image cutout processing unit 415, the image enlargement processing unit 416, and the display image storage unit 417.

  Accordingly, when the switch 411/412 is on the a side, the image data stored in the display image data storage unit 410 is displayed on the display unit 414 as it is. On the other hand, when the switch 411/412 is on the b side, the image data stored in the display image data storage unit 410 is partially cut out by the image cutout processing unit 415, enlarged by the image enlargement processing unit 416, and displayed. It is stored in the image data storage unit 417. Thereafter, the processing up to the display unit 414 is the same as when the switch 411/412 is on the a side.

  The switching of the switches 411/412 is based on information from the device state detection unit 420. When the information indicating that the display unit is set in the vertically long direction (FIG. 1A) is output from the apparatus state detection unit 420, the switch 411/412 is switched to the a side. When the information indicating that the display unit is set in the landscape orientation (FIG. 1B) is output from the apparatus state detection unit 420, the switch 411/412 is switched to the b side.

  FIG. 3A shows a normal display by the function menu screen 201a displayed on the display unit in the vertical direction. Various icons 202a to 205a are displayed at the top of the screen, items 206a to 213a are displayed at the center of the screen, and key buttons are described at the bottom of the screen. 214a to 216a are displayed. 3B shows a state in which the menu screen 201a shown in FIG. 3A is displayed, and the display unit 103 is physically moved from the vertically long direction (FIG. 1A) to the horizontally long direction (FIG. 1B). The function menu screen 201b when the screen is rotated and switched to the enlarged display is shown.

  That is, FIG. 3A shows a normal display state in which the screen 411a is displayed on the display unit 103a set in the portrait orientation when the switch 411/412 is switched to the a side, and FIG. b) shows the state in which the screen 201b is being displayed on the display unit 103b set in the landscape orientation when the switch 411/412 is switched to the b side.

  On the horizontally long screen 201b, a part of the screen displayed on the vertically long screen 201a is cut out and enlarged and displayed. At this time, for the part to be cut out and enlarged, an area including the item 206a indicated by the cursor is designated as a certain area. In FIG.3 (b), the content which expanded the upper part of the screen 201a is displayed as the screen 201b. In the present invention, the various icons 202b to 205b are enlarged and displayed in the same manner as the items 206b and 207b.

  FIG. 4 shows an example of a means for changing the enlarged display area on the same screen as in FIG. 3, and the cursor is moved by the cursor movement key in the key operation unit 106 in the state of the horizontally long screen 301b. The enlarged display area can be changed (scrolled) in accordance with the cursor. It is also possible to display the area 301c where there is no cursor by operating the scroll keys (107 and 108 in FIG. 1). The enlargement magnification in the image enlargement processing unit 416 is Y / X, where X is the horizontal width of the vertical direction screen 301a and Y is the vertical width of the vertical direction screen 301a.

  FIG. 5 is a flowchart showing the basic operation of the present embodiment. Hereinafter, the operation of the present embodiment will be described with reference to FIGS.

  When the screen display is started, normal display (vertical display) image data is created by the display image data generation unit 409 (S502). The created image data is stored in the display image data storage unit 410 (S503). Next, the apparatus state detection unit 420 detects the direction of the display unit (S504). When the display unit is in the portrait orientation in S504, the switch 411/412 is switched to the a side, and the display image data stored in the display image data storage unit 410 is displayed as it is through the data conversion & transmission unit 413. It is transmitted to the unit 414 (S508) and displayed as the portrait screen 103a.

  On the other hand, when the display unit direction detection (S504) indicates the landscape orientation, the image cutout processing unit 415 cuts out the specific area from the image data stored in the display image data storage unit 410 (S505) and cuts out the image. The image is enlarged at a constant magnification (S506). As described above, the magnification is (vertical width of the vertical direction screen) / (horizontal width of the vertical direction screen). The enlarged image data is stored in the display image data storage unit 417 (S507), transmitted to the display unit 414 via the data conversion & transmission unit 413 (S508), and displayed as the landscape screen 103b.

  It is determined whether or not the screen display is finished during the screen display in S508 (S509). If yes, the screen display is finished (S511). If no, it is confirmed whether or not the display image stored in the display image data storage unit 410 has been updated (S510). If the display image is updated, the process returns to the display image data creation (S502) process. If the display image is not updated, it is determined whether or not the direction of the display unit has been switched (S512). If the direction of the display unit has been switched, the process proceeds to display unit direction detection (S504).

  If the direction of the display unit is not switched in S512, it is determined whether or not the current display is a horizontal display (S513). If no, the process proceeds to S509. If yes, it is determined whether or not the display screen has been scrolled (S514). If no, the process proceeds to S509. When the scroll operation is performed, the process proceeds to S505.

  FIG. 6 is a flowchart showing an operation when there is a cursor display when the image cutout processing unit 415 performs cutout. The flowchart shown in FIG. 5 is different from the flowchart shown in FIG. If the cursor is cut out at the center and there is no cursor display, it is different in that an operation to cut out a specific area from the image data for display is performed based on the first line. Since it is the same as that of the flowchart shown in FIG.

  FIG. 7 is a diagram showing an example of a display screen in a portable terminal showing another embodiment of the present invention.

  The basic configuration of this embodiment is the same as that of the above-described embodiment. However, in this embodiment, a method for selecting a region to be cut out and enlarged is further devised. In other words, in the present embodiment, when the enlarged display is changed from the vertically long screen 701a to the horizontally long screen 702b in a standby screen or the like without a cursor display, the area to be enlargedly displayed with broken lines such as 702a and 702c is displayed in the state of the vertically long screen. Allow selection.

  Then, after selecting an area to be enlarged and displayed in the state of the vertically long screen as a broken line frame 701a or 702c, the upper casing 102 provided with the display unit 103 and the receiver 104 is rotated by 90 degrees so that the horizontally long screen is displayed from the vertically long screen. When the screen is switched, the area selected by the broken line frame on the vertically long screen is enlarged and displayed on the horizontally long screen as 702b or 702d.
