Endoscope device and method for controlling display change in endoscope device

1. An endoscope device comprising:

a display; and

a computer configured to:

control the display to:

display a mark image as a first image region; and

display a live image as a second image region;

perform first display change control to set a moving direction of the mark image, as the first image region, to control the display to change a display state of the first image region based on an instruction input to an instruction input device through a first operation method; and

perform second display change control to set the moving direction of the live image, as the second image region, to control the display to change a display state of the second image region based on an instruction input to the instruction input device through a second operation method; and

in response to receiving an operation instruction, fixing a position of the mark image in the display relative to the live image.

2. The endoscope device according to claim 1 , further comprising:

an image sensor configure to capture an image of a subject and to output image data based on the image captured,

wherein the computer is configured to generate an endoscopic image, as the live image, based on the image data output from the image sensor.

3. The endoscope device according to claim 1 ,

wherein the computer is configured to control the display to display the first image region superimposed on the second image region.

4. The endoscope device according to claim 1 ,

wherein the computer is configured to control the display to display the first image region at a predetermined transmittance to allow the second image region to transmit through the first image region.

5. The endoscope device according to claim 1 ,

wherein the computer is configured to:

perform an interchange control to interchange the first image region controlled under the first display change control based on the instruction input through the first operation method with the second image region controlled under the second display change control based on the instruction input through the second operation method, and

following performance of the interchange control,

perform the first display change control to set the moving direction of the live image, as the second image region, to control the display to change the display state of the second image region based on the instruction input through the first operation method; and

perform the second display change control to set the moving direction of the mark image, as the first image region, to control the display to change the display state of the first image region based on the instruction input through the second operation method.

6. The endoscope device according to claim 1 , further comprising:

an image sensor configured to capture a plurality of endoscopic images; and

an insertion portion,

wherein the image sensor is arranged to the insertion portion, and

wherein the insertion portion is configured to perform pan/tilt motion,

wherein the second image region is a live image region for displaying the plurality of endoscopic images as the live image as the plurality of endoscopic images are captured,

wherein the computer is configured to perform the second display change control to set the moving direction of the live image, as the second image region, to control the display to change the display state of the second image region to display the plurality of endoscope images as the insertion portion performs pan/tilt motion of the insertion portion based on the instruction input through the second operation method.

7. The endoscope device according to claim 1 ,

wherein the instruction input device comprises a touch panel,

wherein the first operation method is an operation method in which a first distance from an operation start position to an operation end position on the touch panel is equal to or longer than a predetermined distance, and

wherein the second operation method is an operation method in which a second distance from the operation start position to the operation end position on the touch panel is shorter than the predetermined distance.

8. The endoscope device according to claim 7 ,

wherein the first operation method is a drag operation on the touch panel, and

wherein the second operation method is a tap operation on the touch panel.

9. The endoscope device according to claim 1 ,

wherein the instruction input device comprises a joystick,

wherein the first operation method is an operation method in which a period of tilting time per tilt of the joystick is equal to or longer than a predetermined period of time, and

wherein the second operation method is an operation method in which a period of tilting time per tilt of the joystick is shorter than the predetermined period of time.

10. A method comprising:

controlling a display of an endoscope device to:

display a mark image as a first image region; and

display a live image as a second image region;

performing first display change control to set a moving direction of the mark image, as the first image region, to control the display to change a display state of the first image region based on an instruction input to an instruction input device through a first operation method;

perform second display change control to set the moving direction of the live image, as the second image region, to control the display to change a display state of the second image region based on an instruction input to the instruction input device through a second operation method; and

in response to receiving an operation instruction, fixing a position of the mark image in the display relative to the live image.

11. A computer-readable storage device storing instructions that cause a computer to perform at least:

controlling a display of an endoscope device to:

display a mark image as a first image region; and

display a live image as a second image region;

performing first display change control to set a moving direction of the mark image, as the first image region, to control the display to change a display state of the first image region based on an instruction input to an instruction input device through a first operation method;

perform second display change control to set the moving direction of the live image, as the second image region, to control the display to change a display state of the second image region based on an instruction input to the instruction input device through a second operation method; and

in response to receiving an operation instruction, fixing a position of the mark image in the display relative to the live image.
