  The output unit 13 includes a map output unit 131 and a travel locus information output unit 132.

  The storage unit 11 can store various types of information. The various types of information include, for example, a water map, travel history information, departure position information, and the like described later. The departure position information is position information indicating the departure position. The departure position information may be information indicating a departure position of traveling, or information indicating a position designated by the user. Also, position information usually includes latitude and longitude information. However, as long as the position information can be specified, its format, structure, etc. do not matter.

  The map storage unit 111 can store a water map. The water map of the map storage unit 111 may be stored in advance, or may be received from a server device (not shown). The water map of the map storage unit 111 may be dynamically received from a server device (not shown) as the mobile object moves. The water map is map information including the water surface. The water surface is, for example, on the sea, on the lake, or on the pond. Map information is information which comprises a map. The map information includes, for example, a map image (which may be called map symbol information), one or more objects displayed on the map, and a type of the object. The map information is, for example, in the KIWI format. However, the format, content, etc. of map information do not matter. The map information includes, for example, map symbol information indicating a symbol of a map, and term information having position information indicating a term and the position of the term on the map. The map symbol information is, for example, a bit map or vector data constituting a map. The term has an object (character string) described on the map.

  The processing unit 12 performs various processes. The various types of processing are, for example, current position information acquisition processing and travel locus information acquisition processing described later. The various processes are, for example, departure position information acquisition processing, distance acquisition processing, and the like.

  The departure position information acquisition process is a process of acquiring departure position information, which is position information indicating a departure point, and accumulating the information in the storage unit 11. The processing unit 12 includes, for example, a GPS receiver, and the GPS receiver acquires current position information at the time of departure. This current position information is departure position information. Note that the current position information acquisition unit 121 described later performs acquisition of the current position information. Further, the trigger for the processing unit 12 to obtain departure position information does not matter. The processing unit 12 may acquire departure position information, which is current position information, when, for example, the engine of the mobile unit on which the map output device 1 is mounted is turned on. Further, the processing unit 12 may acquire departure position information, which is current position information, in accordance with, for example, an instruction from the user.

  The distance acquisition process is a process of acquiring distance information on the distance from the departure point to the current point. The processing unit 12 uses the departure position information and the current position information acquired by the current position information acquisition unit 121 to acquire distance information on the distance from the departure point to the current point. The distance information is usually a linear distance. However, the distance information is the distance of the route passed from the departure point, and may be the distance to the current point.

  The current position information acquisition unit 121 continuously acquires current position information. The current position information is position information indicating the current position. Position information is information indicating a position. The position information is, for example, (latitude, longitude). The position information may be, for example, an area ID identifying an area on the map. Here, continuous acquisition may be performed periodically, or may be performed irregularly. There is no limitation on the method of acquiring current position information. Also, the interval at which the current position information acquisition unit 121 acquires current position information does not matter.

  The traveling locus information acquisition unit 122 acquires traveling locus information using two or more pieces of current position information continuously acquired by the current position information acquisition unit 121.

  The traveling locus information is information indicating the traveling locus of the waterborne mobile. The traveling locus information is, for example, a locus line. The locus line is a line indicating a traveling locus. The traveling locus information is, for example, a locus grid. The trajectory grid is a set of regions in which the waterborne vehicle travels. Here, the grid is usually a rectangular area. The rectangle is usually a square, but may be a rectangle or the like. In addition, when travel locus information is a locus | trajectory grid, at least one part of a water surface map is divided into a grid (rectangular area | region).

  When the traveling locus information is a locus line, it is preferable that the traveling locus information acquisition unit 122 acquire traveling locus information so that the current position information of the predetermined range is the same point on the locus line. is there.

  When the traveling locus information is a locus grid, it is preferable that the traveling locus information acquiring unit 122 acquire traveling locus information so that the current position information in a predetermined range is on the same grid.

  It is preferable that the travel locus information acquisition unit 122 acquire travel locus information in different modes according to the scale of the map output by the map output unit 131. For example, when the reduced scale of the map output by the map output unit 131 is small, the traveling locus information acquisition unit 122 uses two or more current position information acquired continuously by the current position information acquisition unit 121, and performs two or more The traveling locus information which is a locus grid having a grid area of 2 is acquired, and when the scale of the map outputted by the map output unit 131 is large, two or more pieces of current position information continuously acquired by the current position information acquiring unit 121 It is suitable to acquire traveling locus information which is a locus line using. In addition, that the reduced scale of a map is that it is a map of a wide area. Also, the fact that the scale of the map is large means that it is a narrow area map. For example, when the reduced scale of the map output by the map output unit 131 is smaller than (or equal to or less than) the threshold, the traveling locus information acquisition unit 122 continuously acquires two or more of the current position information acquisition units 121. The travel locus information which is a locus grid having one or more grid areas is acquired using the current position information, and the scale of the map output by the map output unit 131 is larger than the threshold (or more than the threshold) In this case, it is preferable to acquire traveling locus information, which is a locus line, using two or more pieces of current position information continuously acquired by the current position information acquiring unit 121.

  The travel locus information acquisition unit 122 preferably acquires travel history information having different attribute values based on the number of travels indicated by one or more travel history information in the travel history information storage unit 112.

  It is preferable that the predetermined range differs depending on the scale of the map output by the map output unit 131. Usually, when the scale of the map is small (or below the threshold), the predetermined range is wide, and when the scale of the map is large, the predetermined range is narrow. That is, generally, when the scale of the map is smaller than (or equal to) the threshold, the predetermined range is wide, and when the scale of the map is larger than the threshold, the predetermined range is narrow.

  The travel count acquisition unit 1221 acquires the number of travels using one or more travel history information of the travel history information storage unit 112.

  For example, the traveling history information storage unit 112 stores one or more traveling history information for each traveling. Then, the number-of-travelings acquisition means 1221 acquires, for example, the number of travelings having traveling history information included in the range (area) corresponding to each point constituting the trajectory line. In addition, it is assumed that it is one driving | running | working from engine ON to OFF of a mobile body, and the driving | running | working history information storage part 112 matches and stores 1 or more driving history information acquired during 1 driving | running | working Do.

  For example, the traveling history information storage unit 112 stores one or more sets of information of traveling history information and time information. The number-of-traveling-means acquiring unit 1221 is, for example, traveling history information included in a range (area) corresponding to each point constituting a trajectory, and acquires the number of traveling history information not included in a predetermined time interval. Do.

  The travel locus information acquisition unit 1222 configures travel history information so that the travel count acquired by the travel count acquisition unit 1221 can be distinguished visually. The traveling locus information acquisition unit 1222 acquires, for example, a locus having different attribute values according to the number of travelings acquired by the number of travelings acquiring unit 1221. The different attribute values are, for example, different colors, different line types, and the like. The traveling locus information acquisition unit 1222 acquires, for example, a locus grid having a rectangle having different attribute values according to the number of travelings acquired by the number of travelings acquiring unit 1221. The different attribute values are, for example, different colors, different backgrounds, and the like.

  The travel history information storage unit 123 stores travel history information for the two or more current position information acquired by the current position information acquisition unit 121 in the travel history information storage unit 112. The traveling history information may be the same as the current position information, or may be information in which two or more current position information are aggregated. The information obtained by aggregating two or more pieces of current position information is, for example, information identifying an area including two or more pieces of current position information, position information representing two or more pieces of current position information, or the like.

  The output unit 13 outputs various types of information. The various types of information are, for example, a water map and travel locus information. Here, output is usually display on a display, but projection using a projector, transmission to an external device (usually a display device), storage in a recording medium, other processing devices and other programs It is a concept that includes the delivery of processing results to etc.

  The map output unit 131 outputs a water map which is a map including water. The map output unit 131 normally outputs the water map of the map storage unit 111.

  The traveling locus information output unit 132 outputs the traveling locus information acquired by the traveling locus information acquisition unit 122 on the water map.

  Although the storage unit 11, the map storage unit 111, and the travel history information storage unit 112 are preferably non-volatile recording media, they can be realized also as volatile recording media.

  There is no limitation on the process of storing information in the storage unit 11 or the like. For example, the information may be stored in the storage unit 11 or the like through the recording medium, or the information transmitted through the communication line may be stored in the storage unit 11 or the like. Alternatively, the information input via the input device may be stored in the storage unit 11 or the like.

  The processing unit 12, the travel locus information acquisition unit 122, the travel history information storage unit 123, the travel count acquisition unit 1221, and the travel locus information acquisition unit 1222 can be generally realized by an MPU, a memory, or the like. The processing procedure of the processing unit 12 is usually realized by software, and the software is stored in a storage medium such as a ROM. However, it may be realized by hardware (a dedicated circuit).

  The current position information acquisition unit 121 can be realized by, for example, a GPS receiver.

  The output unit 13, the map output unit 131, and the travel locus information output unit 132 may or may not be considered to include output devices such as a display and a speaker. The output unit 13 can be realized by driver software of an output device or driver software of an output device and an output device.
