Abstract

An image display apparatus that includes: a display screen having a touch panel function on which an image is displayed with operation buttons superimposed on the image, and a switching detection means for detecting a display switching operation for switching the display of the image from the display screen to an external device. When the display switching operation is detected by the switching detection means, the following is performed: the display of the image on the display screen is terminated and image data for displaying the image with the operation buttons superimposed on the image are outputted to the external device from the output terminal; the position information of a touched position on the display screen is detected; and one of the operation buttons displayed on the external device is selected according to the detected position information.

Claims

1. An image display apparatus comprising:

a display screen having a touch panel function;

a display control means for performing control for displaying an image on the display screen with operation buttons superimposed thereon;

a position information detection means for detecting the position information of a touched position on the display screen;

a selection means for selecting one of the operation buttons displayed on the display screen based on the detected position information;

an image data generation means for generating image data for displaying the image on an external device with the operation buttons superimposed thereon; and

an output terminal for outputting the generated image data to the external device, wherein;

the apparatus further comprises a switching detection means for detecting a display switching operation for switching the display of the image from the display screen to the external device; and

if the display switching operation is detected by the switching detection means;

the display control means terminates the display control of the display screen and outputs the generated image data to the external device from the output terminal;

the position information detection means detects the position information of a touched position on the display screen; and

the select means selects one of the operation buttons displayed on the external device according to the detected position information.

2. The image display apparatus according to claim 1, wherein:

the apparatus further comprises a performing means for performing functions, each corresponding to each of the operation buttons; and

if a predetermined touch operation is performed while the display switching operation is detected by the switching detection means and one of the operation buttons is selected by the selection means, the performing means performs the function corresponding to the selected operation button.

3. An image display apparatus comprising:

a display screen having a touch panel function;

a display control means for performing control for displaying an image on the display screen with operation buttons superimposed thereon;

a position information detection means for detecting the position information of a touched position on the display screen;

an image data generation means for generating image data for displaying the image on an external device; and

an output terminal for outputting the generated image data to the external device, wherein;

the apparatus further comprises;

a switching detection means for detecting a display switching operation for switching the display of the image from the display screen to the external device;

a movement direction/trace detection means for detecting the movement direction or the shape of the movement trace of the touched position from the position information detected by the position information detection means; and

a performing means for performing a predetermined function according to the movement direction or the shape of the movement trace of the touched position on the display screen, and

if the display switching operation is detected by the switching detection means;

the display control means terminates the display control of the display screen and outputs the generated image data to the external device from the output terminal;

the movement direction/trace detection means detects the movement direction or the shape of the movement trace of a touched position on the display screen, and

the performing means performs the function corresponding to the detected movement direction or the shape of the movement trace of the touched position.

4. An image display method comprising the steps of:

displaying an image on a display screen having a touch panel function with operation buttons superimposed thereon;

detecting the position information of a touched position on the display screen;

selecting one of the operation buttons displayed on the display screen based on the detected position information;

generating image data for displaying the image on an external device with the operation buttons superimposed thereon; and

outputting the generated image data to the external device from an output terminal, wherein;

the method further comprises the step of detecting a display switching operation for switching the display of the image from the display screen to the external device; and

if the display switching operation is detected,

the display control of the display screen is terminated and the generated image data are outputted to the external device from the output terminal;

the position information of a touched position on the display screen is detected; and

one of the operation buttons displayed on the external device is selected according to the detected position information.

5. An image display method comprising the steps of:

displaying an image on a display screen having a touch panel function with operation buttons superimposed thereon;

detecting the position information of a touched position on the display screen; and

generating image data for displaying the image on an external device; and

outputting the generated image data to the external device from an output terminal, wherein;

the method further comprises the step of detecting a display switching operation for switching the display of the image from the display screen to the external device; and

if the display switching operation is detected;

the display control of the display screen is terminated and the generated image data are outputted to the external device from the output terminal;

the movement direction or the shape of the movement trace of the touched position on the display screen is detected from the movement information of a touched position; and

the function corresponding to the detected movement direction or the shape of the movement trace of the touched position is performed.
