Hand-held device having three-dimensional viewing function with tilt sensor and display system using the same
First Claim
1. A hand-held device comprising:
- an image viewing means having a memory for storing a plurality of image files and image index data mapped to the plurality of image files, wherein said image files and image index data are downloaded from a management server which communicates with said hand-held device and each of said plurality of image files contains an image of goods or thing seen in view of a given position on a sphere, the goods or thing being assumed to be located at a center of the sphere;
a tilt sensor for producing data representing a posture of said hand-held device;
a tilt angle conversion module for receiving said posture data from said tilt sensor and thus producing a tilt value of said hand-held device;
a viewing position decision module for receiving said tilt value from said tilt angle conversion module, setting a reference tilt value of said hand-held device, producing a relative tilt value of said hand-held device with respect to said reference tilt value thereof and producing an image index data transformed from said relative tilt value;
a controller for sensing the operation of said viewing position decision module and accessing said first memory to search an image index data identical with the image index data produced from said viewing position decision module and an image file mapped to said searched image index data; and
a display part for displaying an image of said image file provided from said first memory via said controller of said image viewing means.

Abstract
A hand-held device with 3-dimensional viewing function is disclosed. The hand-held device includes an image viewing circuit. The image viewing circuit has a memory for storing a plurality of image files and image index data mapped to the plurality of image files; a tilt sensor for producing data representing a posture of the hand-held device; a tilt angle conversion module for receiving the posture data from the tilt sensor and thus producing a tilt value of the hand-held device; a viewing position decision module for receiving the tilt value from the tilt angle conversion module, setting a reference tilt value of the hand-held device, producing a relative tilt value of the hand-held device with respect to the reference tilt value thereof and producing an image index data converted from the relative tilt value, and; a controller for sensing the operation of the viewing position decision module and accessing the first memory to search an image index data identical with the image index data produced from the viewing position decision module and an image file mapped to the searched image index data.

6. An image display system comprising:
-
a management server in which an image file database is established, wherein said image file database is comprised of a plurality of image files and image index data mapped to the plurality of image files and each of said plurality of image files contains an image of goods or thing seen in view of a given position on a sphere, the goods or thing being located at a center of the sphere;
a hand-held device having an image viewing means for carrying out 3-dimensional viewing function in cooperation with said image file database and a display part for displaying an image of a given image file among said plurality of image files according to output of said image viewing means; and
a communication network for communication between said management server and said hand-held device with said image viewing means, wherein said image viewing means includes a memory for storing said plurality of image files and image index data mapped to the plurality of image files, wherein said image files and image index data are downloaded from said management server;
a tilt sensor for producing data representing a posture of said hand-held device;
a tilt angle conversion module for receiving said posture data from said tilt sensor and thus producing a tilt value of said hand-held device;
a viewing position decision module for receiving said tilt value from said tilt angle conversion module, setting a reference tilt value of said hand-held device, producing a relative tilt value of said hand-held device with respect to said reference tilt value thereof and producing said image index data transformed from said relative tilt value, and;
a controller for sensing the operation of said viewing position decision module and accessing said first memory to extract an image index data identical with the image index data produced from said viewing position decision module and an image file mapped to said identical image index data.
