In this selection image display processing, when the selection range 40 is smaller than the screen size of the mobile phone terminal 10, the selection range image displayed on the mobile phone terminal 10 is displayed on the notebook PC 1 as shown in FIG. It will be displayed enlarged compared to the state.
On the other hand, when the selection range 40 is larger than the screen size of the mobile phone terminal 10, the image displayed on the mobile phone terminal 10 is reduced and displayed as compared with the display state on the notebook PC 1.
Further, as shown in FIG. 5, the image display data transmitted from the notebook PC 1 to the mobile phone terminal 10 changes according to the movement of the selection range 40, so the image displayed on the mobile phone terminal 10 also changes. .
The selection range 40 can be changed not only by the movement shown in FIG. 5 but also by changing the size of the selection range 40 itself, such as enlargement and reduction, and rotation.

  Note that the image display data according to the present embodiment is, for example, image data (hereinafter referred to as “partial image data”) indicating the image itself of the selection range 40 among the images displayed on the LCD 7. As a specific example, the notebook PC 1 duplicates an image in a range corresponding to the selection range 40 from image data indicating an image displayed on the LCD 7 and transmits it to the mobile phone terminal 10 as partial image data (for example, jpg data). To do. Then, the cellular phone terminal 10 displays the received partial image data on the touch panel 13 using predetermined software (for example, a web browser).

The selection range 40 is, for example, a rectangle, and is similar to the screen size of the mobile phone terminal 10. Thereby, the aspect ratio of the image displayed on the mobile phone terminal 10 does not change from the display state on the notebook PC 1.
For example, the selection range 40 moves while keeping its shape by moving the cursor 6 so that the center point thereof coincides with the vertex of the cursor 6.

When the partial image data from the notebook PC 1 is input via the communication unit 33, the communication control unit 61 outputs the partial image data to the image display control unit 60 and causes the liquid crystal display 13A to display an image based on the partial image data.
That is, when the communication control unit 61 receives image display data indicating an image in the selection range 40 selected by the notebook PC 1 among the images displayed on the notebook PC 1, the image display control unit 60 displays the image display data. Is displayed on the liquid crystal display 13A.

FIG. 8 is a flowchart showing a flow of selected image display processing according to the present embodiment.
The flowchart on the left side (step 100 to step 112) in FIG. 8 is a process in the notebook PC 1, and the flowchart on the right side (step 200 to step 206) is a process in the mobile phone terminal 10.

  First, the selected image table function is enabled in the notebook PC 1 and the mobile phone terminal 10 by the user's operation (step 100, step 200).

  Next, communication between the notebook PC 1 and the mobile phone terminal 10 is established (steps 102 and 202). When the communication is established, the mobile phone terminal 10 transmits size information indicating the size of the touch panel 13 (liquid crystal display 13A) to the notebook PC 1. Upon receiving the size information, the notebook PC 1 sets the selection range 40 as a similar shape of the size of the touch panel 13 based on the size information, and displays the selection range 40 on the LCD 7. The user selects a range of images to be displayed on the mobile phone terminal 10 by moving the selection range 40, enlarging or reducing the size, and the like.

Next, the notebook PC 1 transmits image display data indicating an image in the selection range 40 to the mobile phone terminal 10 (step 104). Note that the transmission of the image display data may be performed after a user operation instruction is input to the notebook PC 1.
When the mobile phone terminal 10 receives the image display data from the notebook PC 1 (step 204), the mobile phone terminal 10 updates the image displayed on the liquid crystal display 13A based on the received image display data (step 206).
When the selection range 40 is changed in the notebook PC 1 (step 106), the notebook PC 1 updates the image display data corresponding to the changed selection range 40 and transmits it to the mobile phone terminal 10 (step 108). When the mobile phone terminal 10 receives new image display data (step 204), the mobile phone terminal 10 updates the image displayed on the liquid crystal display 13A (step 206).
When the image included in the selection range 40 is edited in the notebook PC 1 (step 110), the notebook PC 1 transmits the edited image display data corresponding to the selection range 40 to the mobile phone terminal 10 (step 112). ). When the mobile phone terminal 10 receives new image display data (step 204), the mobile phone terminal 10 updates the image displayed on the liquid crystal display 13A (step 206).

  In the selected image display processing according to the present embodiment, when the selection range 40 is changed, partial image data that is image display data is transmitted even during execution of the change. That is, while the selection range 40 is moving, an image following the movement of the selection range 40 is displayed on the mobile phone terminal 10.

On the other hand, if the partial image data is transmitted to the mobile phone terminal 10 even while the selection range 40 is being changed when the communication speed is low or the data size of the partial image data is large, the mobile phone terminal 10 after the change is completed. There is a possibility that the update of the image by will be delayed. Further, while the selection range 40 is being changed, it is assumed that the user pays attention to the screen of the notebook PC 1 and does not pay much attention to the screen of the mobile phone terminal 10. For this reason, it is considered that the convenience of the user is hardly lowered even if the partial image data is not transmitted to the mobile phone terminal 10 during the execution of the change of the selection range 40.
Therefore, the notebook PC 1 may cause the communication unit 24 to transmit the partial image data after the change is completed without transmitting the partial image data to the mobile phone terminal 10 while the selection range 40 is being changed. Thereby, the selected image display process can smoothly update the image displayed on the mobile phone terminal 10 without delay.
In addition, the case where the change of the selection range 40 is completed is a case where the change of the selection range 40 is not performed more than predetermined time (for example, 0.5 second), for example.

  Furthermore, the present invention is not limited to this, and the notebook PC 1 may cause the communication unit 24 to transmit the image quality of the partial image data while reducing the selection range 40.

  As described above, in the notebook PC 1 according to the present embodiment, the partial range of the image displayed on the LCD 7 can be selected, and the image display data indicating the image of the selected range 40 that is the selected partial range. Is transmitted to the mobile phone terminal 10 which is another information processing apparatus. Therefore, it is possible to provide a dual display that improves the convenience for the user without requiring a work environment.

[Second Embodiment]
Hereinafter, the selected image display process according to the second embodiment of the present invention will be described.

  The configurations of the notebook PC 1 and the mobile phone terminal 10 that construct the image display system 100 according to the present embodiment are the same as the configurations of the notebook PC 1 and the mobile phone terminal 10 according to the first embodiment shown in FIGS. Since there is, description is abbreviate | omitted.

The image display data according to the present embodiment is wide-range image data indicating an image in a wider range than the selection range 40 and position / range data indicating the position and size of the selection range 40. The wide range image data is, for example, image data indicating the entire image displayed on the LCD 7 of the notebook PC 1.
When the selection range 40 is first selected, the notebook PC 1 according to the present embodiment transmits wide-range image data and position / range data to the mobile phone terminal 10 as image display data. When the selection range 40 is changed, the notebook PC 1 transmits only the position / range data as the image display data to the mobile phone terminal 10.

  The cellular phone terminal 10 stores the first received wide range image data in the memory 31. The mobile phone terminal 10 displays an image corresponding to the position / range data in the wide range image data stored in the memory 31 every time the position / range data is received from the notebook PC 1.

  That is, the notebook PC 1 according to the present embodiment first transmits the wide range image data to the mobile phone terminal 10 and then does not transmit the wide range image data even if the selection range 40 is changed. This eliminates the need to transmit image data having a relatively large data capacity every time the selection range 40 is changed. Each time the selection range 40 is changed, only position / range data having a relatively small data capacity is transmitted to the mobile phone terminal 10, and the mobile phone terminal 10 updates an image corresponding to the received position / range data. Therefore, the image displayed on the mobile phone terminal 10 can be updated smoothly without delay.

Furthermore, since the wide range image data is transmitted to the mobile phone terminal 10, the user can change the image displayed on the mobile phone terminal 10 by operating the touch panel 13.
For example, as shown in FIG. 9, when the user swipes rightward on the touch panel 13 of the mobile phone terminal 10, the image displayed on the touch panel 13 moves to the right as shown in FIG. 10. In response to the movement of the image displayed on the mobile phone terminal 10, the selection range 40 displayed on the LCD 7 of the notebook PC 1 also moves to the right.
Similarly, when the user pinches in or out the touch panel 13 of the mobile phone terminal 10, the image displayed on the touch panel 13 is reduced or enlarged. Then, in response to the reduction or enlargement of the image displayed on the mobile phone terminal 10, the selection range 40 displayed on the LCD 7 of the notebook PC 1 is also reduced or enlarged.

  FIG. 11 is a functional block diagram relating to the selected image display process of the mobile phone terminal 10 according to the present embodiment. In FIG. 11, the same components as those in FIG. 7 are denoted by the same reference numerals as those in FIG.

The image display control unit 60 receives a user operation instruction to change the displayed image via the touch sensor 13 </ b> B and the input controller 36.

Further, the image display control unit 60 generates position / range data indicating the position and range of the image displayed on the liquid crystal display 13 </ b> A, and transmits the position / range data to the communication control unit 61.

  The communication control unit 61 causes the communication unit 33 to transmit the input position / range data to the notebook PC 1.

  FIG. 12 is a functional block diagram related to the selected image display process of the notebook PC 1 according to the present embodiment. In FIG. 12, the same components as those in FIG. 6 are denoted by the same reference numerals as those in FIG.

When the communication unit 24 receives the position / range data from the mobile phone terminal 10, the communication control unit 53 outputs the position / range data to the image range selection unit 51.
The image range selection unit 51 updates the position / range data up to that point to the position / range data input from the communication control unit 61, outputs the data to the image display control unit 50, and updates the selection range 40 displayed on the LCD 7. Let
That is, when the range of the image displayed on the mobile phone terminal 10 is changed (moved) in the mobile phone terminal 10, the image range selection unit 51 changes (moves) the selection range 40 in accordance with the change.

  In addition, the image display data generation unit 52 generates wide-range image data and position / range data of the selection range 40 at the beginning of the selected image display process, and outputs the generated data to the communication control unit 53. When the selection range 40 is updated, the image display data generation unit 52 updates and generates position / range data, and outputs only the position / range data to the communication control unit 53.

  As described above, in the selected image display process according to the present embodiment, since the amount of data transmitted from the notebook PC 1 is small, even if the communication speed between the notebook PC 1 and the cellular phone terminal 10 is low, the cellular phone terminal 10 The displayed image can be updated without time delay. In addition, the selected image display process according to the present embodiment can change the selection range 40 displayed on the notebook PC 1 in accordance with the change of the range of the image displayed on the mobile phone terminal 10.
