Image display device and image display method

An image display device comprising:

• an operator motion data acquisition unit configured to acquire operator motion data indicating a first rotation angle produced when an operator who operates a robot performs a rotational motion;
• a robot motion data acquisition unit configured to acquire robot motion data which indicates a second rotation angle produced when the robot performs a rotational motion in accordance with the operator motion data and is transmitted from the robot;
• an image data acquisition unit configured to acquire image data which is generated by being captured by a 360-degree camera provided in the robot and is transmitted from the robot;
• an image correction unit configured to supply, to a display panel, image data in a cutout range obtained by cutting out a range of an image to be displayed on the display panel to be viewed by the operator, from the image data acquired by the image data acquisition unit, and to correct the cutout range;
• a synchronization switch configured to set whether or not to synchronize a rotational motion of the operator with a rotational motion of the robot;
• and
• a synchronization controller configured to perform control so that the operator motion data is transmitted to the robot when the synchronization switch is set to ON which allows synchronization of a rotational motion of the operator with a rotational motion of the robot, and to control the image correction unit to correct the cutout range so as to be equal to a range corresponding to the first rotation angle when there is a difference between the first rotation angle and the second rotation angle, and configured to perform control so that the operator motion data is not transmitted to the robot when the synchronization switch is set to OFF which does not allow synchronization of a rotational motion of the operator with a rotational motion of the robot, and to control the image correction unit to correct the cutout range so as to be equal to a range corresponding to the first rotation angle.
