PROBLEM TO BE SOLVED: To provide an image display device that allows an operator to readily recognize a moving direction of a displayed hook and recognize that the hook actually starts to move.SOLUTION: An image display device 100 includes: a display unit 10 for displaying an image P that is captured by a monitoring camera 300 mounted on a boom and includes a hook; an operational signal acquiring unit 20 for acquiring operational signals S output by an operation input to an operating unit 820; a moving direction setting unit 30 for obtaining a moving direction of the hook relative to a horizontal plane on the basis of the operational signals S ; and an operational signal determining unit 50 for determining whether the operational signals S are operational signals that actually move the hook. The display unit 10 displays a mark representing the obtained moving direction of the hook together with an image of the hook, and varies a display manner of the mark depending on a result of the determination.SELECTED DRAWING: Figure 3 |
