Image control program, image control device, and image control method

Abstract

Provided are an image control program, and the like, that make it possible for a user to easily ascertain the correspondence relationship between points on a route and point information symbols even after an image has been switched from an image including a route line, which has a line shape expressing the route and the points on the route, and the point information symbols to an image including a route line having a different shape and the point information symbols. The following processing is carried out in the present invention: first processing for displaying, on a display unit, a first image including a first line, which indicates a route and has a line shape expressing points on the route, and point information symbols expressing information relating to the points; and second processing for displaying, on the display unit, a second image that is displayed by being switched to from the first image and displays a second line, which indicates the route and has a different shape from that of the first line, such that the points and point information symbols are associated with each other.

1 . An image control device comprising:
 a first processing unit that causes a display unit to display a first image including a first line and a location point information representation, the first line being a line indicating a route and representing a location point on the route with a shape of the line, the location point information representation representing information related to the location point; and   a second processing unit that causes the display unit to display a second image by switching from the first image, the second image displaying a second line to associate the location point with the location point information representation, the second line being a line indicating the route and having a shape different from the shape.   
     
     
         2 . The image control device according to  claim 1 ,
 wherein the second line represents no location point with the shape of the line.   
     
     
         3 . The image control device according to  claim 1 ,
 wherein the second image includes a symbol indicating a correspondence relation between a point on the second line corresponding to the location point and the location point information representation related to the point.   
     
     
         4 . The image control device according to  claim 3 ,
 further comprising   
       a determination processing unit that determines a location of the point on the second line, based on a distance to the location point from a current location as a reference, and
 wherein the second image display the symbol the location determined by the determination processing unit. 
 
     
     
         5 . The image control device according to  claim 1 ,
 wherein the second image is displayed such that the location point information representation displayed in the second image has at least one of a substantially identical display form or a substantially identical display location to the location point information representation displayed in the first image.   
     
     
         6 . The image control device according to  claim 1 ,
 wherein the location point information representation represents information related to a location point where a left or right turn is made, an intersection, or a landmark on the route.   
     
     
         7 . The image control device according to  claim 1 ,
 wherein a length of a line indicating from a current location to a first location point on the first line is substantially identical to a length of a line indicating from the current location to the first location point on the second line.   
     
     
         8 . (canceled) 
     
     
         9 . An image control method by an image control device, the image control method comprising:
 a first processing step of causing a display unit to display a first image including a first line and a location point information representation, the first line being a line indicating a route and representing a location point on the route with a shape of the line, the location point information representation representing information related to the location point; and   a second processing step of causing the display unit to display a second image by switching from the first image, the second image displaying a second line to associate the location point with the location point information representation, the second line being a line indicating the route and having a shape different from the shape.
