Abstract
A map information transmission device includes: a dividing unit configured to divide a region of a map into a plurality of sub regions based on superimposition positions at which a plurality of objects are to be displayed superimposed on the map, the dividing unit performing the division such that a number of objects included in each of the sub regions is a predetermined number or lower; a unit configured to generate, for each of the sub regions, a merged image that includes objects included in a sub region; a unit configured to generate, for each of the sub regions, display code that includes clipping information that designates a clipping region of the merged image that corresponds to the sub region; and a unit configured to transmit the merged image and the display code to a map display device.
