A vision system includes a robot body and a robot operation manipulator that receives inputs from an operator to manipulate the robot body. The vision system also includes a left-eye and right-eye cameras, and a display that displays parallax images for an operator. The vision system further includes an area operation manipulator that receives inputs by the operator to specify a target area to be seen three-dimensionally through the parallax images displayed on the display. The target area is located in an absolute space and is included in a portion of a field of view common between the left-eye and right-eye cameras. The vision system further includes a first controller that controls operation of the robot body, and a second controller that extracts and displays, as parallax images, images corresponding to the target area from a left-eye and right-eye capturing images captured by the left-eye and right-eye cameras, respectively.
