Abstract: According to the present disclosure, a nautical drift managing device is provided. The nautical drift managing device includes an input circuitry to receive destination position information for a watercraft. Further, the nautical drift managing device includes a sensor circuitry to obtain external force information associated with the watercraft. Furthermore, the nautical drift managing device includes processing circuitry to determine, based on the destination position information and the external force information, a drift line associated with a drifting movement of the watercraft when an engine of the watercraft is stopped or neutral.

Abstract: Disclosed is a marine environment display device for georeferencing an image stream of a marine environment captured by a camera. The marine environment display device may comprise an image receiver configured to receive an image of the image stream from the camera, a location receiver configured to receive an object location of an object, an image generator configured to generate, from the image, a projected image having location information associated with each of a plurality of points on the projected image and corresponding to a camera position and field of view of the camera, an object generator configured to generate an object indicator at a position on the projected image based on the object location and the location information, and a display configured to display the projected image and the object indicator at the position on the projected image.

Abstract: Disclosed is a navigation device comprising a processor, memory, and a display. The processor may store a map, minimum and maximum cross track error values, and safety conditions in the memory. The processor may receive a user-inputted route and control display of the route on the map such that if the route is within the safety conditions at a maximum width, the route is displayed in a first display mode. If at least a portion of the route at the maximum width is not within the safety conditions, the route width is reduced, and if the route is within the safety conditions at the reduced width, the route is displayed in the first display mode at the reduced width, but if the route is not within the safety conditions at a minimum width, the route is displayed in a second display mode at the minimum width.

Abstract: A display device for controlling a remotely controlled camera is disclosed. The display device comprising an image receiver configured to receive an image of the image stream from the camera, and a processor. The processor including a retriever configured to retrieve a selected buffered image corresponding to a data insufficiency region within a target field of view while adjusting the camera from a current field of view to the target field of view until the image stream from the camera includes the insufficiency region being depicted within the target field of view and a depicter configured to depict the selected buffered image on the display device at least in the insufficiency region.

Abstract: Methods and apparatuses perform image processing for blending image and/or data layers. The method according to one embodiment accesses data representing a first layer and data representing a second layer; and generates a blended layer by adjusting a transparency of said first layer relatively to said second layer based on data associated with said first or second layer.

Abstract: Methods and apparatuses process sensing signals. A method for redrawing a sensing image when a range is or has been changed, according to one aspect of the present invention, records the sensing image and outputs the sensing image to a display; records additional information displayed upon a screen and outputs the additional information to the display; computes a new image from the recorded sensing image using an image manipulation computer function, so that the computed image fits a new scale of the changed range, and recording the computed image; and computes changes to the recorded additional information to adjust the additional information to the new scale of the changed range, and records the computed additional information.
