Image information displaying apparatus
First Claim
1. An image information displaying apparatus comprising:
- a casing of a size that can be held and operated by hand, said casing having a horizontal orientation and a vertical orientation;
a display unit built into said casing for displaying an image;
a two-dimension position sensor for detecting a direction and a distance when said casing is moved in an XY-plane;
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 two-dimension position sensor,wherein the partial image information selection controller detects movement of the casing along a Z-axis perpendicular to the XY plane of the casing such that,when the casing is in the horizontal orientation, movement of the casing along the Z-axis causes movement of the displayed image along a height of the image information, andwhen the casing is held in the vertical orientation, movement of the casing along the Z-axis causes movement of the displayed image along a cross-section of the image information.

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.

1. An image information displaying apparatus comprising:
-
a casing of a size that can be held and operated by hand, said casing having a horizontal orientation and a vertical orientation; a display unit built into said casing for displaying an image; a two-dimension position sensor for detecting a direction and a distance when said casing is moved in an XY-plane; 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 two-dimension position sensor, wherein the partial image information selection controller detects movement of the casing along a Z-axis perpendicular to the XY plane of the casing such that, when the casing is in the horizontal orientation, movement of the casing along the Z-axis causes movement of the displayed image along a height of the image information, and when the casing is held in the vertical orientation, movement of the casing along the Z-axis causes movement of the displayed image along a cross-section of the image information. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 12)

10. An image information displaying apparatus comprising:
-
a casing of a size that can be held and operated by hand, said casing having a horizontal orientation and a vertical orientation; a display unit built into said casing for displaying an image; a two-dimension 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 two-dimension 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, wherein the partial image information selection controller detects movement of the casing along a Z-axis perpendicular to the XY plane of the casing such that, when the casing is in the horizontal orientation, movement of the casing along the Z-axis causes movement of the displayed image along a height of the image information, and when the casing is held in the vertical orientation, movement of the casing along the Z-axis causes movement of the displayed image along a cross-section of the image information. - View Dependent Claims (11, 13)
