Image display method for mobile terminal in image distribution system, and image conversion apparatus and mobile terminal using the method

An image display method for a mobile terminal in an image distribution system, comprising the steps of:

• storing images picked up by an imaging unit in an image storage distribution apparatus;
• if said mobile terminal requests an image specified by said mobile terminal to be displayed, causing said image conversion apparatus to obtain said specified image from said image storage distribution apparatus and then to distribute said specified image to said mobile terminal;
• causing said mobile terminal to display said image distributed by said image conversion apparatus on the screen of a monitoring unit located in said mobile terminal;
• causing said mobile terminal to specify an optional location and range of said displayed image and transmit information on said specified location and range to said image conversion apparatus;
• causing said image conversion apparatus to enlarge the image of said location and range specified by said mobile terminal from the image specified by said mobile terminal to a proper display size to said monitoring unit of said mobile terminal and then to distribute said enlarged image to said mobile terminal;
• and
• causing said mobile terminal to display said enlarged image distributed by said image conversion apparatus on the screen of said monitoring unit.

A mobile terminal comprising:

• a monitoring unit for displaying an image distributed and received from the outside through a transmission path;
• a storage unit for storing the process comprising the steps of:
• specifying an optional location and range of said displayed image and transmitting information on said specified location and range to the outside;
• receiving an image of said specified location and range enlarged to a proper display size to said monitoring unit of said mobile terminal;
• and
• displaying said enlarged image displayed from said image conversion apparatus on the screen of said monitoring unit.

An image conversion apparatus comprising:

• an interface for receiving information distributed from the outside through a transmission path and distributing the information to the outside;
• and
• a storage unit for storing the process comprising the steps of:
• if a mobile terminal requests an image specified by said mobile terminal itself to be displayed, obtaining said specified image, distributing said specified image to said mobile terminal, and displaying said specified image on a monitoring unit of said mobile terminal;
• and
• when receiving information on the specified location and range of said displayed image from said mobile terminal, enlarging the image of a location and range specified by said mobile terminal from the image specified by said mobile terminal to a proper display size to said monitoring unit of said mobile terminal, distributing said enlarged image to said mobile terminal, and then causing said mobile terminal to display said enlarged image on said monitoring unit.
