Abstract

Disclosed is an image displaying device including a first touch panel arranged on a display screen and generating first coordinate information representing a first coordinate pair denoting the location of a touch on the panel surface; a second touch panel arranged at the rear of the display screen and generating second coordinate information representing a second coordinate pair denoting the location of a touch on the panel surface; and a control unit detecting concurrent touches on the surfaces of the first and second touch panels and, if the concurrent touches are detected, detecting coordinate pairs overlapping between the first coordinate pairs and the second coordinate pairs to determine whether or not the overlapping coordinate pairs exist in a number not lower than specified. A method of and a program for displaying an image on such an image displaying device are also disclosed.

a control unit adapted to detect concurrent touches on the surfaces of the first and second touch panels based on the first coordinate information and the second coordinate information and, if the concurrent touches are detected, detect coordinate pairs overlapping between first coordinate pairs represented by the first coordinate information on one hand and second coordinate pairs represented by the second coordinate information on the other to determine whether or not the overlapping coordinate pairs exist in a number not lower than specified; and

an image processing unit adapted to use one or both of the first coordinate information and second coordinate information to subject an image displayed on the display unit to image processing if the overlapping coordinate pairs are detected in a number not lower than specified.

2. The image displaying device according to claim 1, wherein:

if said overlapping coordinate pairs exist in a number not lower than specified, said control unit causes a selection screen for selecting one image processing from a plurality of image processings to be displayed on said display unit at a location denoted by a first coordinate pair, and selects one image processing from a plurality of image processings listed on the selection screen in accordance with first coordinate information generated when the image processing is selected by a user from the image processings on the selection screen; and

said image processing unit uses one or both of said first coordinate information and second coordinate information to subject an image displayed on said display unit to the image processing as selected.

3. The image displaying device according to claim 1, wherein said control unit detects coordinate pairs overlapping between said first coordinate pairs and said second coordinate pairs and determines whether or not the overlapping coordinate pairs exist in a number not lower than specified if a period of time from generation of said first coordinate information representing a first coordinate pair to generation of said second coordinate information representing a second coordinate pair or a period of time from the generation of said second coordinate information representing a second coordinate pair to the generation of said first coordinate information representing a first coordinate pair is equal to or shorter than a predetermined period of time.

4. The image displaying device according to claim 1, wherein said image processing comprises at least one out of scaling of an image, plane rotation of an image, z-axis rotation of an image, emphasizing of a specified area, and modification of playback environment.

5. The image displaying device according to claim 4, wherein, if the scaling of an image is selected by said control unit, said image processing unit scales up or down an image based on second coordinate information generated through a movement of an operating means in contact with said second touch panel in a first direction or a direction opposite to the first direction.

6. The image displaying device according to claim 4, wherein, if said plane rotation of an image is selected, said image processing unit rotates an image in a plane about a center of rotation having a third coordinate pair represented by second coordinate information generated through a touch of an operating means on said second touch panel by an angle defined by the center of rotation as well as points having fourth and fifth coordinate pairs, respectively, based on second coordinate information generated through a movement, from the point with the fourth coordinate pair to the point with the fifth coordinate pair, of the operating means in contact with the second touch panel that has been removed temporarily from the second touch panel and brought again into contact with the second touch panel.

7. The image displaying device according to claim 4, wherein, if said z-axis rotation of an image is selected, said image processing unit subjects an image to z-axis rotation based on second coordinate information generated through a movement of an operating means in contact with said second touch panel in a first direction or a direction opposite to the first direction.

8. The image displaying device according to claim 4, wherein, if said emphasizing of a specified area is selected, said image processing unit subjects a specified area of an image whose center is positioned at a location denoted by a coordinate pair represented by second coordinate information generated through a touch of an operating means on said second touch panel, to one processing selected from among zooming, color conversion, color inversion, contrast adjustment, and change of playback speed.

9. The image displaying device according to claim 4, wherein, if said modification of playback environment is selected, said image processing unit performs fast forward or rewind of images or adjustment of playback sound level based on second coordinate information generated through a movement of an operating means in contact with said second touch panel in a first direction or a direction opposite to the first direction.

10. The image displaying device according to claim 1, wherein each of said first and second touch panels detects a touch of an operating means on the surface of the relevant panel if the operating means is tapped on the surface specified times within a certain period of time.

11. The image displaying device according to claim 1, wherein each of said first and second touch panels detects a touch of an operating means on the surface of the relevant panel if the operating means is kept in contact with the surface for a certain period of time.

12. A method of displaying an image on an image displaying device provided with a display unit for displaying images, a first touch panel arranged on a display screen of the display unit and adapted to detect a touch on a surface of the first touch panel to generate first coordinate information representing a coordinate pair denoting a location of the touch, and a second touch panel arranged at the rear of the display screen of the display unit and adapted to detect a touch on a surface of the second touch panel to generate second coordinate information representing a coordinate pair denoting a location of the touch, comprising:

a first step of detecting concurrent touches on the surfaces of the first and second touch panels based on the first coordinate information and the second coordinate information;

a second step of detecting coordinate pairs overlapping between first coordinate pairs represented by the first coordinate information on one hand and second coordinate pairs represented by the second coordinate information on the other if the concurrent touches are detected; and

a third step of using one or both of the first coordinate information generated by the first touch panel and the second coordinate information generated by the second touch panel to subject an image displayed on the display unit to image processing if the overlapping coordinate pairs exist in a number not lower than specified.
