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.

Claims

1. A display device, comprising:

a detector for detecting a touch operation;

an image acquirer for acquiring 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 display device, an underwater detection image created based on information obtained from an ultrasonic transducer for detecting underwater directly under the display device, and a radar image obtained from a radar antenna for detecting a location of an object around the display device;

a display unit for displaying acquired images in respective divided areas of a display screen;

a gesture detector for detecting a predetermined touch gesture based on the touch operation detected by the detector;

an operated location detector for detecting an operated location of the touch gesture;

a divided area identifier for identifying which image among the images is displayed in the divided area corresponding to the operated location detected by the operated location detector; and

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.

2. The display device of claim 1, 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 the direction of scrolling or zooming when the image in the identified divided area is the underwater detection image.

3. The display device of claim 1, the image processor does not limit the motion range of scrolling or zooming when the image in the identified divided area is the navigation image, and limits the motion range of scrolling or zooming when the image in the identified divided area is the radar image.

4. The display device of claim 1, wherein the image processor fixes the direction of scrolling or zooming when the image in the identified divided area is the underwater detection image, and does not fix the direction of scrolling or zooming when the image in the identified divided area is the radar image.

5. The display device of claim 3, wherein the image processor limits the motion range of scrolling or zooming centering on the location of the display device when the image in the identified divided area is the radar image.

6. The display device of claim 4, wherein the underwater detection image is an image where an underwater state directly under the display device is associated with time, and

wherein the image processor fixes the direction of scrolling to a time-axis direction when the image in the identified divided area is the underwater detection image, and fixes the direction of the zooming to a direction perpendicular to the time-axis.

7. The display device of claim 1, wherein the display device is carried in a ship.

8. A display device, comprising:

a detector for detecting a touch operation;

an image acquirer for acquiring at least two or more images generated based on signals acquired by different sensors;

a display unit for displaying the acquired images in respective divided areas of a display screen;

a gesture detector for detecting a predetermined touch gesture based on the touch operation detected by the detector;

an operated location detector for detecting an operated location of the touch gesture;

a divided area identifier for identifying 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.

9. A display method, comprising:

a detection step for detecting a touch operation;

an image acquisition step for acquiring 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 display device, an underwater detection image created based on information obtained from an ultrasonic transducer for detecting underwater directly under the display device, and a radar image obtained from a radar antenna for detecting a location of an object around the display device;

a display step for displaying acquired images in respective divided areas of a display screen;

a gesture detection step for detecting a predetermined touch gesture based on the touch operation detected at the detection step;

an operated location detection step for detecting an operated location of the touch gesture;

a divided area identification step for identifying which image among the images is displayed in the divided area corresponding to the operated location detected at the operated location detection step; and

an image processing step having a function to perform scrolling or zooming of the display screen corresponding to the touch gesture, 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.
