Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows an overall configuration diagram of an embodiment of the present invention. The external storage device 10 uses, for example, an IC card, a CD-ROM, a DAT or the like as a read-only non-volatile storage medium, and on the map. Map data 11, which is obtained by digitizing each point, coordinate data 12 for points such as stations, city halls, ports, and display pattern data 13 are stored in advance. The external storage device 10 is connected to a control device 40 described later, and necessary information is read by the control device 40. The input device 20 includes a touch switch or the like, and issues a command such as a specific point and date to the control device 40 by a user's screen touch operation.

The control device 40 inputs outputs from the external storage device 10 and the input device 20 and inputs A / D (analog / analog).
Interface 41 for processing such as digital) conversion
A CPU 42 that performs various image data processing and performs various calculations based on output data sequentially sent from the interface 41, various processing programs that perform calculations by the CPU 42, and other necessary information are written in advance. ROM (Read Only Memory) 43
And a RAM (random access memory) for writing and reading information necessary for executing the program. For example, the control device 40
Calculates the time of high tide / low tide, the time of sunrise / sunset, the time of moonrise / moonset, the type of spring tide / neutral tide based on the input data input by the input device 20. Based on, create a screen to display this information.

A display device 30 as an output device is connected to the control device 40. This display device 30 is C
A display 34 such as RT, a graphic memory 32 including a V-RAM, and the like, and a graphic controller 31 that draws map data sent from the control device 40 as image data in the graphic memory 32 and outputs the image data. The display controller 33 controls to display a map screen on the display 34 based on the graphic controller 31.

Next, the operation of this embodiment will be described based on the flowchart shown in FIG. Here, it is assumed that the program is read from the ROM 43 when the display menu is selected by the touch operation of the input device 20 by the user on the input device 20, and the arithmetic processing of the program is executed in step 100. . First, in step 110, the map data is read from the external storage device 10, the CPU 42 of the control device 40 creates a map screen, and the map screen is displayed on the display 34 of the display device 30. Then, the process proceeds to step 120, and in this step 120, the point that the user wants to see is selected by touching the input device 20 from the displayed map screen and determined.

Next, in step 130, the CPU 42 of the control device 40 performs various calculations described later on the basis of the input data to calculate necessary information. First, the latitude / longitude of the point is calculated from the coordinates of the input point. The calculated latitude and longitude,
The sunrise / sunset time is calculated from the input date and the data of the rotation period and the revolution period of the earth stored in the ROM 43 in the control device 40. Similarly, the latitude / longitude, the input date, and R in the control device 40
From the data of the revolution cycle of the moon stored in OM43,
Calculate the age of the day, moonrise and moonset times. Further, the times of high tide and low tide are calculated from the latitude / longitude, the input date, and the data of the revolution cycle of the month stored in the ROM 43 in the control device 40. Also, the types of spring tide and spring tide are calculated from the age of the moon.

The various calculations described above can be performed as follows. First, the sunrise / sunset times can be obtained by calculating the positional relationship between the sun and the latitude / longitude of a designated point on the earth from the rotation and revolution cycles of the earth. The age of the moon is about 29.5.
Since it is repeated at day intervals, it can be obtained by preparing reference data. In addition, since the moon rotation cycle is about 27 days / lap and the earth's rotation cycle is 24 hours / lap, the moon rotation and the moon rotation times are calculated as follows: It will be delayed by 24 hours / 27 days = about 50 minutes), and can be calculated by preparing the reference data.

Further, the high tide is on a straight line connecting the earth and the moon (on the ground, the point where the moon is directly above and behind it), and the low tide is from the straight line to the left and right. It is a point in the direction of 90 degrees. Therefore, high tide and low tide are 2 every 24 hours and 50 minutes for the same reason as above.
It will happen each time and can be obtained by preparing the reference data. In addition, the high tide occurs at the new moon and the full moon, and the low tide occurs at the upper and lower lunar months, so these information can be obtained if the age of the moon is known.

After performing various calculations in step 130 in this way, the process proceeds to the next step 140, in which the CPU 42 of the control device 40 is operated.
Performs image processing on the basis of various calculation results obtained in step 130. This image processing data is sent to the display device 30 and is displayed by being superimposed on the map screen on the display 34 of the display device 30. Then, the process proceeds to step 150, and in this step 150, the program ends.

A display example of this output screen is shown in FIG. 3, and the mark A is displayed in an easy-to-understand manner on the set point portion on the map near the point set by the user for viewing information.
The mark A point is displayed not on the center of the screen but on either side. Then, an information window is displayed at a position not overlapping the mark, and necessary information is selected and displayed in this information window. For example, as shown in FIG. 3, the contents of the information displayed when selecting the information on fishing and clamming are the name of the set point, the date, the time of sunrise / sunset obtained by calculation, and the time of high tide / low tide. ,
Only required information of type information such as spring tide and spring tide is provided.

In the present embodiment configured as described above, by designating a specific point and date on the map displayed on the display 34, the time of high tide / low tide, sunrise / sunset of the specific point can be designated. The CPU 42 of the control device 40 can automatically calculate the time of day, the moonrise time, the moonset time, etc., and display them on the map screen on the display 34 of the display device 30. Can be called at any time when needed.

In the above-mentioned embodiment, the spot is set by selecting the spot from the map screen.
You can also enter the longitude to set the location. Specifically, the latitude and longitude are directly input by touching the input device 20. In this case, in order to output the set location as a map on the screen, it is necessary to newly read the map of the corresponding location from the external storage device 10 based on the input latitude and longitude data.

Further, by touching the input device 20,
It can be done by entering the name of the municipality. In this case, since the set point is not a point but a range having a certain size, the calculation is performed by the representative point of the range, for example, the coordinates of the city hall. Further, in the above-described embodiment, the setting point is input by the touch operation of the input device 20, but it is also possible to input by voice. In this case, as shown in FIG. 4, the voice recognition device 50 is used as an input device.
Is required. Further, although the calculated information is output only by the display device in the above-described embodiment, it may be output by voice. In this case, as shown in FIG.
An audio output device 60 such as an amplifier and a speaker is required.
