Abstract: A point which requires visual attention is added to map data. A map data generation device acquires image data in which the outside is captured from a vehicle by an input device and a point data of the vehicle, associates both data, and generates a visual saliency map acquired by estimating fluctuation of visual saliency based on the image data by the visual saliency extraction unit. Then, whether or not a point or a section indicated by position information corresponding to the visual saliency map is a point or a section which requires visual attention is analyzed based on the visual saliency map by an analysis unit, and the point or the section which requires the visual attention is added to the map data based on an analysis result of the analysis unit by an addition device.
