[0002]

2. Description of the Related Art Conventionally, in an industrial plant, for example, in the field of material handling, a monitor and control device for operating a control target while watching a monitor screen such as a television monitor has been widely used.

FIG. 6 is a block diagram showing the configuration of this type of monitoring and control device. The monitoring control device executes a predetermined display process based on an image camera 2 that shoots a turntable 1 as a control target and sends an image signal and an image signal received from the image camera 2 to monitor a CRT 4.
