ATTACHMENT AREA MEASURING APPARATUS, ATTACHMENT AREA MEASURING PROGRAM AND ATTACHMENT AREA MEASURING METHOD

PROBLEM TO BE SOLVED: To provide an attachment area measuring apparatus which measures an attachment area of a waterdrop attaching to the inside of a reaction gas supplying channel of a fuel cell. SOLUTION: The attachment area measuring apparatus comprises: a non-water image acquiring section for acquiring first data of an image photographed in such the state that no liquid attaches to an attachment object; a filled image acquiring section for acquiring second data of an image photographed in such the state that the liquid attaches to the whole area of the attachment object; a difference image creating section for creating data of a difference image between above first and second data images; a fist threshold image creating section for extracting a brightness value equal to or more than a prescribed threshold from above difference image data and creating threshold image data; an input image acquiring section for acquiring input image data in such the state that the liquid attaches to the attachment object; a binarized image creating section which creates calculation image data by performing a prescribed calculation based on the input image data, the threshold image data and the first or second image data, and carries out a binarizing process by using a prescribed brightness value; and an area calculating section for measuring the attachment area of the liquid based on the binarized image data.
