Abstract

A bidirectional display method includes: receiving an image signal inputted from an external device; displaying an image on a screen on the basis of a display signal; detecting an operation on the screen; outputting the display signal for displaying the image formed by combining an external image based on the image signal and an operation input object corresponding to the operation on the screen; detecting a predetermined operation as a movement instruction; and outputting the display signal for displaying the external image moved in a direction toward a side of the screen when the movement instruction is detected.

Claims

1. A bidirectional display method comprising:

receiving an image signal inputted from an external device;

displaying an image on a screen on the basis of a display signal;

detecting an operation on the screen;

outputting the display signal for displaying the image formed by combining an external image based on the image signal and an operation input object corresponding to the operation on the screen;

detecting a predetermined operation as a movement instruction; and

outputting the display signal for displaying the external image moved in a direction toward a side of the screen, when the movement instruction is detected.

2. The bidirectional display method according to claim 1, wherein

in the detecting of the movement instruction, an operation to a predetermined area in the screen is detected as the movement instruction.

3. The bidirectional display method according to claim 1, wherein

when the movement instruction is detected, each external image of a plurality of the external images is moved in a different direction from the others.

4. The bidirectional display method according to claim 1, wherein

when the movement instruction is detected, each external image of a plurality of the external images is moved by a different distance from the others.

5. The bidirectional display method according to claim 1, wherein

when the movement instruction is detected, a plurality of the external images is moved in such a way as to contact each other.

6. A bidirectional display device comprising:

an image signal input unit which receives an image signal inputted from an external device;

a display unit which displays an image on a screen on the basis of a display signal;

an operation detection unit which detects an operation on the screen;

a movement instruction detection unit which detects a predetermined operation as a movement instruction; and

a drawing unit which outputs the display signal for displaying the image formed by combining an external image based on the image signal and an operation input object corresponding to the operation on the screen, and outputs the display signal for displaying the external image moved in a direction toward a side of the screen when the movement instruction is detected.
