Abstract

An internet moving image linking system is provided that can reduce link information necessary for the related information in a moving image linkage. The internet moving image linking system includes a server and a user terminal. The server has means for judging the presence or absence of a link destination based on point time information and point coordinate information each transmitted from the user terminal.

Claims

1. An internet moving image linking system comprising:

a server; and

a user terminal;

wherein said server comprises;

a moving image distributor for distributing a moving image to said user terminal;

an image detector for detecting a static image at a corresponding time based on point time information transmitted from said user terminal; and

an image recognizer for recognizing a specific portion of an image designated by said user based on point coordinate information transmitted from said user terminal and based on said static image detected by said image detector,

a link point storage for storing link point information;

a link point detector for detecting a link point at a point time based on point time information and link point information transmitted from said user terminal; and

a link point comparator for comparing the coordinate of an image recognized by said image recognizer with the coordinate of a link point detected by said link point detector, and

wherein said linking point storage only stores a link destination for every point designating abrupt change in a movement of a specific portion of an image.

2. The internet moving image linking system defined in claim 1, wherein when the specific portion of the image is moving linearly, the link point detector interpolates a link destination for said specific portion of the image.

3. The internet moving image linking system defined in claim 2, wherein the link point detector calculates all link destinations for the point time information provided by said user based on relative movement of specific portions of the image.

4. The internet moving image linking system defined in claim 3, wherein each said relative movement is calculated based on the link destination of a previous point designating the abrupt change in the movement of the specific portion of the image and the link destination of a next point designating the abrupt change in the movement of the specific portion of the image and wherein the point time information received from the user terminal is between a point time information of the previous point and a point time information of the next point.

5. The internet moving image linking system defined in claim 4, wherein the link point comparator compares the calculated link destinations of the image with the recognized specific portion of the image designated by said user.

6. The internet moving image linking system defined in claim 1, wherein the abrupt change in a movement of a specific portion of an image is substantially non-linear movement of the specific portion of the image.
