Patent number: 8880341Abstract: A display method and apparatus for displaying three-dimensional terrains and route guidance achieves a flexible and high detail three-dimensional display operation by enabling to change parameters, such as a viewing angle of a selected three-dimensional object, a height of a selected three-dimensional object, and a level of details (LOD) of a selected part of the image. The display method and apparatus also enables to compensate discontinuity, if any, at a border portion of two or more images where such parameters have been changed. Since such a change is made only a selected portion or object on the three-dimensional image, a computation power, memory space or other resources of the navigation system may not be overburdened by such operations.Type: GrantFiled: January 16, 2013Date of Patent: November 4, 2014Assignee: Alpine Electronics, Inc.Inventors: Maung Han, Benjamin Poiesz

Patent number: 8203578Abstract: A display method and apparatus for a navigation system utilizes enables a smooth map scroll operation when a scroll direction is changed sharply. Such a smooth map scroll operation is applied to a situation where such a change of scroll direction is within a predetermined angle range by adding a scroll direction bias for each movement. The display method dynamically adjusts the scroll direction bias and the update frequency depending on the degree of direction change and the available system resources such as a processing speed in the navigation system. Therefore, the navigation system is able to display the smooth operation of the map scroll so that the user is able to recognize the images actually illustrated on the screen and to reach the intended location of the map image quickly and accurately.Type: GrantFiled: October 30, 2007Date of Patent: June 19, 2012Assignee: Alpine Electronics, Inc.Inventor: Maung Han

Patent number: 7925428Abstract: A method and apparatus for a navigation system efficiently stores the data associated with a calculated route to the destination in a backup memory by incorporating a direction coding method. The method and apparatus can be advantageously implemented in such a situation where the operation of the navigation system is terminated during the route guidance operation before reaching the destination. Since each direction code requires a small amount of data bit, an overall amount of data for the calculated route can be dramatically reduced and can be stored in a small memory space. When the navigation system is restarted, the calculated route will be reproduced based on the direction codes retrieved from the backup memory, thereby enabling to continue the route guidance operation to guide the user the destination.Type: GrantFiled: December 6, 2007Date of Patent: April 12, 2011Assignee: Alpine Electronics, Inc.Inventor: Maung Han

Publication number: 20060247855Abstract: A navigation system is designed to scale a map image such that a redrawn map image shows an icon of the most relevant object at a center of a cursor when the scale of the map image is changed so that the user will not lose sight of the most relevant object such as an icon. The navigation system prioritizes an icon representing a particular object based on predetermined priority order and changes the position of the map image so that the icon of the highest priority comes to the center of the cursor when the map scale is changed. Thus, the icon of the highest priority always remains at the center of the cursor, thereby preventing from loosing the sight of the icon of the highest priority when zooming in the map image.Type: ApplicationFiled: April 28, 2005Publication date: November 2, 2006Inventors: Andrew de Silva, Maung Han

Publication number: 20050177305Abstract: A display method and apparatus for a navigation system which is capable of preventing blank scroll of a display screen when there is no visible objects within a display range when the screen is scrolled and immediately jumping to the screen where a visible object exists. When a display screen is scrolled, if there is no visible object within a display range of the scroll for a relatively long period of time, the display screen just shows a blank screen, which may confuse the user or make the user feel uneasy. The display method and apparatus avoids the blank scrolling by automatically scrolling to a screen where a visible object is shown.Type: ApplicationFiled: February 6, 2004Publication date: August 11, 2005Inventor: Maung Han
