A tidal current information display device for a movable body includes a position measurement module to detect a position of the movable body, a geographical information selection module to determine geographic information to be displayed on a display screen based on the detected position, a tidal current information receiving module to receive and store tidal current information based on the detected position, a tidal current information display module to generate display data for displaying a first graphical user interface (GUI) for displaying the tidal current information corresponding to a predetermined position on the geographic information displayed on the display screen, and a voyage time calculation module to calculate an estimated time for the movable body to reach the predetermined position. The first GUI is configured for showing at least one of: the estimated time and a direction and speed of a tidal current at the estimated time.

Tidal current information display device

The purpose is to provide a nautical chart display device which enables a measurement of a distance on an electronic nautical chart, like a measuring method which is performed by using a divider. The nautical chart display device includes a display unit, an operation detector, a registration processing module, and a change processing module. The display unit has a screen and displays a nautical chart on the screen. The operation detector detects a touch operation to the screen. The registration processing module accepts two points of the touch operation on the screen, and registers a scale at which a distance between the touched points on the screen matches a distance setting on the nautical chart as an additional scale. The change processing module changes the scale of the nautical chart to the additional scale.

Nautical chart display device, nautical chart display method, and nautical chart display program

The purpose is to provide a nautical chart display device which enables to easily grasp a direction centering on a reference position. The nautical chart display device includes a display, a detector, a directional symbol displaying module, and a directional symbol changing module. The display displays a nautical chart on a screen. The detector detects an operation to the screen. The directional symbol displaying module displays, on the display so as to be superimposed on the nautical chart, a directional symbol in which directional markers arranged in a circle and the center of the circle are indicated. The directional symbol changing module moves the directional symbol according to an operation to the directional symbol.

A navigational information display device is provided, which may include a display configured to display a navigational image indicated using a geometrical figure related to first navigational information, and further display one or more characters selected from the group consisting of a first navigational information character indicative of the first information, a second navigational information character indicative of second navigational information, and a device operation character related to operation of the display device, and processing circuitry configured to receive input of an instruction signal to instruct a change in a display orientation of the screen, and to change a display orientation of at least one of the one or more characters while maintaining a display orientation of the navigational image when the input of the instruction signal is received.

Navigational information display device, and method of displaying navigational information

An underwater detection device is provided, which includes an echo signal processing module configured to acquire echo signals and detect signal levels of the echo signals corresponding to water depths, the echo signals being reflection waves caused by ultrasonic waves transmitted underwater, a detection image display controlling module configured to display on a display unit a detection image indicating the signal levels of the echo signals corresponding to the water depths and placed in a chronological order, and a menu display controlling module configured to display first superordinate menu buttons on the detection image displayed on the display unit, one of the first superordinate menu buttons displayed in one of end sections of the detection image where oldest information is displayed, the rest of the first superordinate menu buttons displayed to extend from the one of the first superordinate menu buttons in one of depth directions and time axis directions.
