1. A display device for installation in a ship, comprising:
- a detector that detects a touch operation;
an image acquirer, associated with the display device, that acquires at least two of a navigation image containing map or nautical chart information created based on information obtained from a GNSS sensor for detecting a location of the ship, an underwater detection image created based on information obtained from an ultrasonic transducer for detecting underwater directly under the ship, and a radar image obtained from a radar antenna for detecting a location of an object around the ship;
a display unit that displays acquired images in respective divided areas of a display screen;
a processor executing a gesture detector that detects a predetermined touch gesture based on the touch operation detected by the detector, an operated location detector that detects an operated location of the touch gesture, and a divided area identifier that identifies which image among the images is displayed in the divided area corresponding to the operated location detected by the operated location detector;
an image processor having a function to perform scrolling or zooming of the display screen corresponding to the touch gesture, and for changing a direction or a motion range according to the image being displayed in the identified divided area, upon performing the scrolling or zooming, wherein the image processor applies a limitation to scrolling or zooming based on the identified image corresponding to the operated location of the touch gesture; and
wherein the image processor does not fix the direction of scrolling or zooming when the image in the identified divided area is the navigation image, and fixes zooming to a one dimensional zoom direction when the image in the identified divided area is the underwater detection image.

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.
