PROBLEM TO BE SOLVED: To provide a recognition processing device and recognition processing method for a state indicator capable of separately grasping the positions of many kinds of state indictors including an indicator even if they have the same shape and stably recognizing the display content in conformation to the change of hue, saturation, or brightness of an image by the influence of sunlight, luminaire or the like. SOLUTION: A marker is detected from an image signal obtained by imaging the state indicator and the marker present near the state indicator so as to be included within an imaging range, and the color, position, geometric shape or the like for the state indicator is precisely calculated from the marker to surely grasp the position of the state indicator, and the display content of the state indicator is recognized. |
