Abstract

This invention is relative to an image information display apparatus in which a large-sized image can readily be recognized even with use of a small-sized display unit such as is provided in a portable telephone set or in a mobile computer.

It is assumed that an observer (user) 122 is about to recognize an image of a larger size 121 using an image information display apparatus 124 having a display 123 of a smaller size. When the observer 122 moves his or her hand 126, a partial area 125 of an image demonstrated in the display 123 is actively changed. This permits the image of a larger size 121 to be comprehended readily in its entirety. The image of a larger size 121 can readily be recognized by having the hand movement matched to the movement of the display image (partial area 125 of the image), based on perceptual characteristics of the human being.

Claims

1. An image information displaying apparatus comprising:

a casing of a size that can be held and operated by hand,

a display unit built into said casing for displaying an image;

a position sensor for detecting a direction and a distance when said casing is moved;

an image information storage unit for storing the image information of an image size larger than an image size that permits display at a time on said display unit;

a display image range selection unit for selecting a partial image information of a display range that can be displayed at a time, from the image information stored in said image information storage unit, and for outputting the selected information to said display unit for display; and

a partial image information selection controller for moving the image selected by said display image range selection unit according to the direction and the distance of the casing movement as selected by said position sensor.

2. The image information displaying apparatus according to claim 1 wherein

said position sensor detects the movement by substituting two-dimensional movement for spatial movement of said casing, and wherein said partial image information selection controller moves the image selected by said display image range selection unit in relationship to the substituted two-dimensional movement.

3. The image information displaying apparatus according to claim 1 wherein

said position sensor detects the movement by substituting three-dimensional movement for spatial movement of said casing, and wherein said partial image information selection controller moves the image selected by said display image range selection unit in relationship to the substituted three-dimensional movement.

4. The image information displaying apparatus according to claim 1 wherein said image information storage unit stores the image information downloaded over a communication network.

5. The image information displaying apparatus according to claim 1 wherein said partial image information selection controller includes a point of origin coordinate data registration unit for registering the coordinate of a point of origin serving as a reference for a display frame in slicing a portion of the image information stored in said image information storage unit to said display unit for display thereon, and a selection instructing unit for causing said display image range selection unit to select sequentially the display range of the partial image determined by said display frame by sequentially changing the coordinate of said point of origin in relationship to the direction and the magnitude of spatial movement of said casing as detected by said position sensor.

6. The image information displaying apparatus according to claim 1 further comprising a switch for on/off setting as to whether or not the spatial movement of said casing sequentially detected by said position sensor is to be reflected in registered contents of said point of origin coordinate data registration unit.

7. The image information displaying apparatus according to claim 1 wherein said image information storage unit is a memory in a computer.

8. The image information displaying apparatus according to claim 1 wherein said display image range selection unit is implemented by a CPU and a memory in a computer and the functions of a computer software stored in said memory.

9. The image information displaying apparatus according to claim 1 wherein said partial image information selection controller is implemented by a CPU and a memory in a computer and the functions of a computer software stored in said memory.

12. The apparatus of claim 1,

wherein the image information storage unit stores partial images of an unknown image of a larger size than the display unit, and

wherein the display range image selection unit selects the partial images in a sequence such that the unknown image is assembled from the partial images in accordance with movement of the case.

10. An image information displaying apparatus comprising:

a casing of a size that can be held and operated by hand,

a display unit built into said casing for displaying an image;

a position sensor for detecting a direction and a distance when the casing is moved;

a stereoscopic model information storage unit having the stereoscopic model information stored therein;

a two-dimensional image information outputting unit for changing an observing point in keeping with movement of said casing as detected by said position sensor to generate and output the two-dimensional image information from the stereoscopic model, wherein the two-dimensional image information is based on the changed viewing point; and

a display image range selection unit for selecting partial image information from the two-dimensional image information and outputting the selected partial image information to the display unit, wherein the partial image information is displayed at a time on said display unit.

11. The image information displaying apparatus according to claim 10 wherein said two-dimensional image information outputting unit generates and outputs an image for a right eye and an image for a left eye for stereoscopy and wherein said display unit displays said image for a right eye and the image for a left eye in such a manner as to enable stereoscopy.

13. The apparatus of claim 10,

wherein the image information storage unit stores partial images of an unknown image of a larger size than the display unit, and

wherein the display range image selection unit selects the partial images in a sequence such that the unknown image is assembled from the partial images in accordance with movement of the case.
