| 20080238914 | Map Information Creating Device, Map Information Creating Method, and Map Information Creating Program - A 3D road object is an object having road width, height, and length. The 3D road object corresponds to a link. A road surface texture is drawn repeatedly on the top surface of the 3D road object. With a map information creating device, geometry data in a cube shape containing a cross-section including the road width and the height can be extracted. Length of this geometry data can be set to the length of one sheet (one cycle) of the road surface texture in the length direction of the 3D road object. The road surface texture for one sheet as well as drawing cycle information can also be extracted. Moreover, link length information can be extracted from the link. | 10-02-2008 |

| 20090174715 | DISPLAY PROCESSING DEVICE, DISPLAY PROCESSING METHOD, AND DISPLAY PROCESSING PROGRAM - A font controller extracts and reads each time only the pre-rasterized bitmap font data groups to be used simultaneously among a plurality of pre-rasterized bitmap font data groups stored on the hard disk drive in advance, and expands and stores the groups in a work memory. With this arrangement, it is possible to significantly decrease the amount of memory consumed because the memory capacity required in the work memory is sufficient only with the read data amount to be extracted. | 07-09-2009 |
| 20090248292 | ROUTE GUIDANCE DEVICE, ROUTE GUIDANCE METHOD, AND ROUTE GUIDANCE PROCESSING PROGRAM - To reliably avoid a dangerous zone by setting a route from a current position to a temporary destination so as to avoid the dangerous zone while reflecting prediction results of a moving direction even when a route setting is not previously made. A route to a temporary destination is set based on location information obtained and prediction results of a moving direction of a user, so that even when an avoidance scheduled route for avoiding a dangerous zone has not been decided in advance, the route from the current position to the temporary destination can be reliably set so as to avoid the dangerous zone, while reflecting the prediction results of the moving direction. As a result, safe and reliable route guidance while avoiding the dangerous zone can be executed. | 10-01-2009 |

| 20090315881 | DISPLAY PROCESSING DEVICE, DISPLAY PROCESSING METHOD, AND DISPLAY PROCESSING PROGRAM - In case it is necessary to have high-speed drawing processing such as display scrolling and so on, a drawing switching signal is input at a step, and high-speed drawing display data is output to a display at a step in response to this input, thereby display is performed. A high-speed drawing data generating means generates high-speed drawing display data for displaying each pixel concerning a character or visual object using a digitized gradation value digitized from each corresponding gradation value, and display is performed on this generated data. When it is necessary to have high-speed drawing, it is possible to have quick processing without increasing loads on a CPU and graphic controller on digitized data from gradation value. | 12-24-2009 |
