Bending operation control for endoscope

1. An endoscope apparatus comprising:

a display configured to display an endoscopic image obtained by picking up an image of an object with an image pickup sensor;

a touch panel provided in the display;

an insertion section including a bendable bending section;

an operation section including at least one operation device; and

a processor, wherein the processor is configured to:

determine whether a first instruction input by the operation section is detected,

perform first operation control on the bending section when determining that the first instruction input is detected,

determine whether a second instruction input by the touch panel is detected,

perform second operation control different from the first operation control on the bending section when determining that the second instruction input is detected;

perform bending control of the bending section based on a first movement amount, in the first operation control; and

perform bending control of the bending section based on a second movement amount, in the second operation control, the second movement amount being smaller than the first movement amount.

2. The endoscope apparatus according to claim 1 , wherein

the at least one operation device is a joystick, and

the first instruction input is an instruction input by an operation method of operating the joystick.

3. The endoscope apparatus according to claim 2 , wherein

the first operation control includes operation control for causing the bending section to perform a bending motion by a distance corresponding to a tilting amount of the joystick in a direction in which the joystick is tilted, and

the second operation control includes operation control for causing the bending section to perform the bending motion by a distance corresponding to a contact time period of the touch panel in a direction toward a contact position of a finger.

4. The endoscope apparatus according to claim 2 , wherein

the first operation control includes operation control for causing the bending section to perform a bending motion in a direction in which the joystick is tilted, and

the second operation control includes operation control for causing the bending section to perform the bending motion to move from a contact end position toward a contact start position of a finger on the touch panel or move from the contact start position toward the contact end position.

5. The endoscope apparatus according to claim 2 , wherein

the display is configured for displaying an image for operation, and

the second instruction input is an instruction input by an operation method of operating the touch panel with the image for operation.

6. The endoscope apparatus according to claim 5 , wherein the operation panel is hidden while the instruction input by the joystick is performed.

7. The endoscope apparatus according to claim 1 , wherein the second instruction input is an instruction input by an operation method of stroking the touch panel.

8. The endoscope apparatus according to claim 1 , wherein the second instruction input is an instruction input by an operation method of tapping the touch panel.

9. An operation control method for an endoscope apparatus comprising:

determining whether a first instruction input by an operation section including at least one operation device is detected;

performing first operation control on a bendable bending section provided in an insertion section when determining that the first instruction input is detected;

determining whether a second instruction input by a touch panel provided in a display configured to display an endoscopic image obtained by picking up an image of an object with an image pickup sensor is detected;

performing second operation control different from the first operation control on the bending section when determining that the second instruction input is detected;

performing bending control of the bending section based on a first movement amount, in the first operation control; and

performing bending control of the bending section based on a second movement amount, in the second operation control, the second movement amount being smaller than the first movement amount.

10. A non-transitory storage medium having an operation control program for an endoscope apparatus stored therein, the operation control program causing a computer to execute:

a code for determining whether a first instruction input by an operation section is detected;

a code for performing first operation control on a bending section when determining that the first instruction input is detected;

a code for determining whether a second instruction input by a touch panel is detected;

a code for performing second operation control different from the first operation control on the bending section when determining that the second instruction input is detected;

a code for performing bending control of the bending section based on a first movement amount, in the first operation control; and

a code for performing bending control of the bending section based on a second movement amount, in the second operation control, the second movement amount being smaller than the first movement amount.
