Abstract

An image display device includes a display unit (DU) and an operation screen, a first operation unit on the DU generating an operation signal, a second operation unit on a rear of the DU generating an operation signal, a hold state (HS) detection unit detecting a HS of the image display device, an image display mode decision unit determining an image display mode for displaying the image on the DU according to the HS, an image processor determining a content of the image to be displayed according to the HS, and an operation control unit controlling the first and second operation units according to the HS. A user interface of the DU is changed to a user interface corresponding to the HS by changing, according to the HS, one or more of the image display mode/content of the image, and a method for controlling the first and second operation units.

an operation control unit for controlling the first operation unit and the second operation unit according to the hold state detected by the hold state detection unit, wherein a user interface of the display unit is changed to a user interface corresponding to the hold state of the image display device by performing one or more of processing by the image display mode decision unit to change the image display mode for displaying the image on the display unit according to the detected hold state, processing by the image processor to change the content of the image to be displayed on the display unit according to the detected hold state, and processing by the operation control unit to change a method for controlling the first operation unit and the second operation unit according to the detected hold state.

2. The image display device of claim 1, wherein when the hold state detection unit detects that the first operation unit is operated by an operator'"'"'s thumbs whereas the second operation unit is operated by one or more of the operator'"'"'s index finger, middle finger, ring finger, and little finger, the hold state detection unit detects that the hold state is such that the image display device is held in the operator'"'"'s both hands.

3. The image display device of claim 2, wherein when the hold state is such that the image display device is held in the operator'"'"'s both hands, the image and the operation screen displayed in the display unit are associated with a movable range of one of the operator'"'"'s fingers operating the second operation unit, the movable range being estimated by detecting a length of the one operating finger and being smaller than a screen of the display unit.

4. The image display device of claim 3, wherein the movable range of the one finger operating the second operation unit is changed according to a position where the image display device is supported.

5. The image display device of claim 3, wherein when three fingers of the index finger, middle finger, ring finger, and little finger are in contact with the second display unit, remaining one finger is judged to be the one finger operating the second operation unit.

6. The image display device of claim 1, wherein the second operation unit is also provided on a lateral side of the display unit.

7. The image display device of claim 1, wherein when the hold state is such that the image display device is placed on a desk or a table or held in the operator'"'"'s single hand, the image display device is operated using only the first operation unit.

8. The image display device of claim 1, wherein the first operation unit provided on the display unit is a touch panel.

9. The image display device of claim 1, wherein a display unit for displaying at least one of the image and the operation screen is provided also on the rear side.

10. The image display device of claim 9, wherein the second operation unit is a touch panel provided on the display unit on the rear side.

11. The image display device of claim 1, wherein the image display device is a digital photograph frame.

12. An image display device for displaying an image comprising:

a display unit for displaying at least one of the image and an operation screen,

a first operation unit provided on the display unit and for generating an operation signal by detecting a contact with itself,

a second operation unit provided on a lateral side of the display unit and for generating an operation signal by detecting a contact with itself,

a hold state detection unit for detecting a hold state of the image display device according to the operation signal generated by at least one of the first operation unit and the second operation unit,

an image display mode decision unit for determining an image display mode for displaying the image on the display unit according to the hold state detected by the hold state detection unit,

an image processor for determining a content of the image to be displayed on the display unit according to the hold state detected by the hold state detection unit, and

an operation control unit for controlling the first operation unit and the second operation unit according to the hold state detected by the hold state detection unit,

wherein a user interface of the display unit is changed to a user interface corresponding to the hold state of the image display device by performing one or more of processing by the image display mode decision unit to change the image display mode for displaying the image on the display unit according to the detected hold state, processing by the image processor to change the content of the image to be displayed on the display unit according to the detected hold state, and processing by the operation control unit to change a method for controlling the first operation unit and the second operation unit according to the detected hold state.

13. The image display device of claim 12, wherein when the hold state is such that the image display device is placed on a desk or a table or held in the operator'"'"'s single hand, the image display device is operated using only the first operation unit.

14. The image display device of claim 12, wherein the first operation unit provided on the display unit is a touch panel.

15. The image display device of claim 12, wherein a display unit for displaying at least one of the image and the operation screen is provided also on the lateral side.

16. The image display device of claim 15, wherein the second operation unit is a touch panel provided on the display unit on the lateral side.

17. The image display device of claim 12, wherein the image display device is a digital photograph frame.

18. An image display method for displaying an image on an image display device comprising a display unit for displaying the image and an operation screen, a first operation unit provided on the display unit, and a second operation unit provided on a rear side of the display unit, comprising the steps of:

a step of displaying the image and the operation screen on the display unit,

a step of generating a first operation signal by detecting through the first operation unit a contact with the first operation unit itself,
