Description

  The present invention relates to a display device for displaying fishing data, a display method, and a display program.

  The ship is equipped with various devices. For example, there is a track recording device that records a track, a target position, a target, etc. and displays them on a display (see, for example, Patent Document 1). The track recording device described in Patent Document 1 displays a target position or a target on a display as a mark figure.

JP-A-8-334376

  Although the track recording device of Patent Document 1 displays event information at the time of navigation such as a target position, a target, etc. by a mark figure, the explanation of the figure is displayed by characters. Further, the shape of the mark figure for each piece of event information is set by the user each time.

  For this reason, the user may find it difficult to intuitively recognize what data the displayed graphic represents. In particular, when displaying a lot of event information, it is difficult to recognize at a glance.

  In addition, conventional navigation devices such as the track recording device described in Patent Document 1 can recognize specific locations such as event information, etc., and specific trajectories, but recognize fishing information in the area in which the ship travels. I can not do it.

  Then, the objective of this invention is providing the display apparatus and display method which display the data which can sense surrounding fishing information sensuously.

  A display device according to the present invention includes a database, a fishing data acquisition unit, a display mark acquisition unit, and an image data generation unit. The database stores position data, fishing data, types of fishing data, and display marks in a linked manner. The fishing data acquisition unit acquires the content of the selected fishing data from the database. The display mark acquisition unit acquires a mark corresponding to the selected fishing data from the database. The image data generation unit generates image data and displays the image data by superimposing a mark whose display mode is adjusted according to the content of fishing data on the map data.

  In this configuration, fishing data is displayed as a mark, and the display mode of the mark is changed according to the content of the fishing data. Thereby, for example, the user can sense the contents of fishing data sensuously as compared to the case where fishing data is displayed in characters.

  According to the present invention, the user can easily grasp sensory data on surrounding fishing data and its contents.

  FIG. 1 is a block diagram showing a configuration of a display device according to the present embodiment. FIG. 2 is a diagram showing an outline of a database in which fishing data and position data are linked. FIG. 3 is a diagram for explaining a database in which fishing data and display marks are linked.

  The display apparatus 1 which concerns on this embodiment is mounted in ships, such as a fishing boat, for example. The display device 1 includes a display unit 10, a selection unit 11, a ship position acquisition unit 12, a display control unit 13, a time acquisition unit 14, and a storage unit 15. The display control unit 13 includes a fishing data acquisition unit 131, a display mark acquisition unit 132, and an image data generation unit 133.

  The display unit 10 displays screen data including fishing data. Although the details will be described later, the screen data includes chart data and fishing data selected by the user. The chart data is, for example, centered on the position of the ship identified by the positioning system provided in the ship.

  The fishing data includes, for example, data on water temperature, water depth, fishing fruit (fished amount, fish species, etc.), bottom sediment, tidal current, etc. Various data of fishing data are displayed with a predetermined mark figure. For example, in the example shown in FIG. 3, the "water temperature" data is displayed in a diamond shape. The "water depth" data is displayed in a circle. The "fishing" data is displayed in positive form. "Tidal current" data is displayed in triangles.

  The display form of the display mark of fishing data (a mark figure representing fishing data) is changed according to the content. The “display form” according to the present embodiment is, for example, the color tone of the display mark. For example, a circular mark indicating “water depth” data is displayed in dark blue as the water depth increases, and as light blue as the water depth decreases (see FIG. 6).

  The selection unit 11 is an operation means for the user to input which type of fishing data is to be displayed. The selection unit 11 may be a touch panel, an operation dial, a keyboard, or the like, or may be a microphone for voice input. The selection unit 11 outputs the selected type of fishing data to the fishing data acquisition unit 131 and the display mark acquisition unit 132 of the display control unit 13.

  The own ship position acquisition unit 12 acquires, for example, position data of the own ship specified by the positioning system. The own ship position acquisition unit 12 outputs the acquired position data to the fishing data acquisition unit 131 and the image data generation unit 133 of the display control unit 13.

  When the fishing data acquisition unit 131 receives the type of fishing data from the selection unit 11, the fishing data acquisition unit 131 acquires fishing data of that type from the storage unit 15.

  Specifically, the storage unit 15 stores a database (DB) 151. The database 151 corresponds to the "first database" according to the present invention. As shown in FIG. 2, the database 151 stores fishing data and position data in association with each other. As shown in FIG. 2, the position data is latitude data and longitude data. And fishing data are water temperature, water depth, tidal current, fishing fruit, and sediment. The type of fishing data is not limited to this.

  The fishing data acquisition unit 131 acquires fishing data of a predetermined area based on position data indicating the position of the ship. More specifically, the fishing data acquisition unit 131 acquires fishing data associated with each position data of the area to be used as image data, including the position of the ship. More preferably, in consideration of the movement of the ship itself, it is preferable to acquire fishing data of a wide area in a predetermined portion of the area used as image data at that time.

  In addition, when each fishing data stored in the database 151 has a concept such as time, season, etc., the fishing data acquisition unit 131 responds to the time or season based on the time acquired by the time acquisition unit 14 Fishing data is acquired from the database 151.

  The fishing data acquisition unit 131 outputs the position data and fishing data linked to each other to the image data generation unit 133.

  When receiving the type of fishing data from the selection unit 11, the display mark acquisition unit 132 acquires, from the storage unit 15, a mark figure according to the type of fishing data.

  Specifically, the storage unit 15 stores a database (DB) 152. The database 152 corresponds to the "second database" according to the present invention. As shown in FIG. 3, the database 152 associates and stores the type of fishing data and the mark figure. In the case of FIG. 3, a rhombus is linked to the fishing data "water temperature", a circle is linked to the fishing data "water depth", and a positive shape is linked to the fishing data "fishing", and the fishing data "waterflow" ", The triangle is tied. Crossings are linked to the fishing data "bottom sediment".

  For example, if the water temperature is selected as fishing data, the display mark acquisition unit 132 acquires a diamond from the database 152.

  The display mark acquisition unit 132 outputs the acquired mark figure to the image data generation unit 133.

  The image data generation unit 133 acquires the chart data corresponding to the area including the position of the own ship acquired by the own ship position acquisition unit 12 from a storage unit (not shown) in which the chart data is stored in advance.

  The image data generation unit 133 superimposes the mark figure input from the display mark acquisition unit 132 on the chart data. At this time, the image data generation unit 133 arranges the mark figure at the position represented by the position data linked to the fishing data from the fishing data acquisition unit 131.

  The image data generation unit 133 adjusts the display mode of the mark figure according to the contents of the fishing data. For example, when the fishing data is “water temperature”, the image data generation unit 133 sets the color darker as the position of the water temperature is higher and lighter as the position of the water temperature is lower (see FIG. 5).

  The image data generation unit 133 displays the chart data on which the mark is superimposed on the display unit 10.

  FIG. 4 is a flowchart showing the process executed by the display device 1.

  The display device 1 acquires chart data based on the own ship position (S1). The display device 1 acquires fishing data and position data linked to the fishing data from the database 151 of the storage unit 15 based on the selected type of fishing data (S2).

  The display device 1 acquires the mark figure associated with the selected fishing data from the database 152 of the storage unit 15 (S3). The display apparatus 1 adjusts the display mode of the mark figure acquired by S3 based on the fishing data acquired by S2 (S4). Then, the display device 1 generates the image data by superimposing the mark figure of the adjusted display form on the position on the chart data acquired in S1 according to the position data acquired in S2 (S5).

  As described above, displaying fishing data as marks makes it easier for the user to intuitively recognize fishing data as compared to displaying fishing data using only characters. In particular, because there is shaking on the ship, when it is displayed in text, it may be difficult to read the text, but by displaying it as a mark, the data content can be recognized at first glance.

  Further, by displaying the mark on the chart, for example, the user can easily grasp the contents of the fishing data at each position on the chart, and the fishing work can be performed efficiently. Also, by changing the display mode of the mark according to the data content, the user can more easily grasp the content of the fishing data.

  The contents of fishing data corresponding to the mark may be displayed as text data by selecting each mark described above. For example, text data may be popped up.

  In the above description, the color tone is shown as the display mode, but the size of the mark may be used as the display mode.

  Further, in the present embodiment, the sea area displayed on the display unit 10 may be a sea area designated by the user. Furthermore, in the present embodiment, the display mark uses a simple figure, but it may be a figure that easily reminds the user of the contents of the fishing data. For example, the display mark of fishing data "fishing" may be an image of fish, and the display mark of fishing data "water temperature" may be an image of a thermometer.

  Next, display modes of various fishing data will be described with reference to the drawings.

  FIG. 5 is a diagram showing an example of a screen when “water temperature” is displayed as fishing data.

  In this example, fishing data "water temperature" is displayed as a circular mark in the portion of the sea 102 of the chart. At this time, as shown in FIG. 5, the circular mark is changed to a color corresponding to the water temperature and displayed. That is, in this example, the color of the display mark corresponds to the “display form” according to the present invention. For example, the color of the circular mark displayed at the position where the water temperature is high is reddish, and the color of the circular mark displayed at the position where the water temperature is low is bluish. As a result, the user can easily check the water temperature distribution and easily predict good fishing places.

  FIG. 6 is a diagram showing an example of a screen when “water depth” is displayed as fishing data.

  In this example, fishing data "water depth" is displayed as a circular mark in the portion of the sea 102 of the chart. At this time, as shown in FIG. 6, the circular mark is changed to a color corresponding to the water depth and displayed. That is, in this example, as in FIG. 5, the color of the indication mark corresponds to the “display form” according to the present invention. For example, the density of the circular mark displayed at the deep water position is increased, and the density of the circular mark displayed at the shallow water position is reduced. Thereby, the user can easily confirm the water depth distribution.

  FIG. 7 is a diagram showing an example of a screen in the case of displaying “Tidal Current” as fishing data.

  In this example, fishing data “tidal current” is displayed by an arrow mark in the portion of the sea 102 of the chart. At this time, the arrow mark changes the line width according to the speed of the tidal current, and is displayed so that the direction of the arrow coincides with the direction of the tidal current. That is, in this example, the line type and the direction of the display mark correspond to the “display form” according to the present invention. As a result, the user can easily find tides and can perform fishing work efficiently. Note that the density or color of the line may be changed according to the speed of the tidal current.

  FIG. 8 is a view showing an example of a screen in the case of displaying fishing data "fishing".

  In this example, fishing data "fishing fruit" is displayed in a bar-like mark on the portion of the sea 102 of the chart. At this time, the bar-like mark is displayed with its length changed in accordance with the fishing result. That is, in this example, the length of the bar-like mark corresponds to the “display form” according to the present invention. For example, a bar-shaped mark displayed at a position with a large amount of fishing is made longer, and a bar-shaped mark displayed at a position with a small amount of fishing is shortened. As a result, since the fishing fruit data can be represented by a bar graph, the user can easily confirm the fishing fruit distribution, which helps to discover a good fishing ground.

  Although FIGS. 5-8 demonstrated the case where one type of fishing data was displayed, you may display several types of fishing data simultaneously.

  FIG. 9 is a diagram showing an example of a screen when “water temperature” and “tidal current” are displayed as fishing data. In this example, the fishing data “water temperature” described in FIG. 5 and the fishing data “tidal current” described in FIG. 7 are superimposed and displayed. This makes it easier for the user to understand the relationship between the water temperature and the tidal current (tidal tide), and helps to find a good fishing ground.

  Although two types of fishing data are simultaneously superimposed and displayed in FIG. 9, the respective fishing data may be alternately displayed.

  In the above description, the case where fishing data corresponding to all the display target positions of the mark are stored is shown. However, depending on the location, fishing data may not be stored. In this case, as shown below, fishing data may be complemented and displayed for a position where fishing data is not stored in advance. FIG. 10 (A) is a diagram showing a display example in the case of not complementing the fishing data, and FIG. 10 (B) is a diagram showing a display example in the case of complementing the fishing data.

  In the case of FIG. 10 (A), there is no fishing data of position PA. Therefore, as shown in FIG. 10A, the mark of the position PA is not displayed. When detecting that there is no fishing data at the position PA where the mark is to be displayed, the image data generation unit 133 acquires fishing data of the position PB1 adjacent to the position PA and fishing data of the position PB2.

  The image data generation unit 133 complements the fishing data of the position PA using the fishing data of the position PB1 and the fishing data of the position PB2. For example, the image data generation unit 133 calculates an arithmetic average value of the value of the fishing data at the position PB1 and the value of the fishing data at the position PB2, and uses it as the value of the fishing data at the position PA.

  The image data generation unit 133 sets the display mode of the mark 112A using the fishing data of the position PA.

  By using such a configuration and processing, it is possible to display a mark of a display mode considered to be suitable for the position where fishing data is stored in advance.

  In addition, although complementing processing was performed using the fishing data aligned in the longitudinal direction in the above description, the fishing data aligned in the latitude direction may be used. Further, the complementing process may use fishing data of a plurality of positions surrounding positions where fishing data is not stored in two dimensions set by longitude and latitude. In this case, for example, it is possible to use an averaging process according to the distance between the position at which fishing data is not stored and each position around it.

  Although the database 151 is stored in the storage unit 15, it is updated as needed. The update may be performed manually by the user or automatically on a regular basis. For example, the user may update fishing data of "fishing" by inputting from an input unit (not shown). In addition, the display device 1 may include a communication unit, and may receive fishing data of “water temperature” or fishing data of “tidal current” from the outside, and may update the database 151 based on the received data. Alternatively, the database 151 may be updated by acquiring data from a tidal meter provided in a ship equipped with the display device 1.

  In the above description, only fishing data is displayed. However, navigation event data such as a target position, a predicted track, or data set by the user may be displayed together with the fishing data.

  Moreover, although the aspect which divided the database 151 and the database 152 was shown in the above-mentioned description, these may be unified to one database. In this case, the database stores the type and content of fishing data, and a mark corresponding to the fishing data. Further, in this case, the display mode may be linked and stored in accordance with the contents of the fishing data.

  In the embodiment described above, the case where the display device 1 is mounted on a ship has been described, but the above configuration and processing can be applied to any mobile object that requires fishing data.
