Abstract: A touch panel device includes a display unit, a detector, and a controller. The display unit displays an image (nautical chart) on a display screen. The detector detects touches at two positions on the display screen and touched positions thereof. The controller displays a distance and azimuths between the touched positions, based on the two touched positions that are detected by the detector and either one of coordinates on the image corresponding to the touched positions and information associated with the coordinates (positional information).

Abstract: A touch panel device (display device) acquires a first sensor image, a second sensor image, and a third sensor image. The touch panel device displays acquired images in respective divided areas of a display screen. The touch panel device detects a predetermined touch gesture and detects an operated location of the touch gesture. The touch panel device identifies which image the operated location indicates. The touch panel device performing processing corresponding to the identified touch gesture (scrolling or zooming of a display image), and changes a direction or a motion range of the processing according to the identified sensor image.

Abstract: A radar device is provided in this disclosure. The radar device includes an area determination module for performing a determination of a noise superior area or a target-echo superior area for each divided area of a radar-search area defined in advance, a noise-level calculation module for calculating a noise level for a divided area based on received signals from the divided area that is determined as the noise superior area, and an interpolation module for interpolating or extrapolating the calculated noise level for the divided area that is determined as the noise superior area, to obtain a noise level for a divided area that is determined as the target-echo superior area.
