<p><P>PROBLEM TO BE SOLVED: To provide a quality discrimination device of a visual field capable of preventing the quality discrimination mistake of the visual field in the case where an edge extraction target is absent. <P>SOLUTION: The quality discrimination device of the visual field is provided with an imaging means to discriminate the quality of the visual field on the basis of the image taken by the imaging means and equipped with far infrared imaging devices 1R and 1L and a visible imaging device 2 all of which are provided as imaging means, a matter detecting means for detecting matter from the images acquired by the far infrared imaging devices 1R and 1L, a number-of-matter judging means for judging whether the number of matters is a threshold value or above on the basis of the detection result of the matter detecting means, an edge extraction means for extracting an edge from an image region which is the image acquired by the visible imaging device 2 and contains the matter in the case where the number-of-matter judging means is judged to be a predetermined number or above and a quality discrimination means of the visual field for discriminating the visual field on the basis of the edge extracted by the edge extraction means. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
