<P>PROBLEM TO BE SOLVED: To more properly display a map image whose colors change. <P>SOLUTION: A change amount of a first parameter which varies at least a part of color attributes including color tune, saturation degree and brightness of a map image depending on a season and a date belonging to the season is set based on date information indicating a date (S160 and S170). A change amount of a second parameter which varies at least a part of the color attributes depending on one of time zones and a time in the time zone is set based on time information indicating various time zones and times corresponding to location information indicating a location on a map to be displayed and the date information (S190 to S220). An image for display in which the change amount of the first parameter and the change amount of the second parameter are reflected to the map image to be displayed is displayed on a display (S180, S190 to S250). Thus, a color change which occurs as the seasons pass and a color change caused by sunlight can be expressed more properly. <P>COPYRIGHT: (C)2013,JPO&INPIT |
