Abstract
A method of detecting the base concentration of a film is provided including: a film image entering process of reading a developed film with an image pickup device to generate the pixel values in each of the RGB color components; a non-exposure region detecting step of detecting the edge of each frame on the film from the detected pixel values and specifying as the non-exposure region each line of pixels disposed at the intermediate between any two adjacent frame-image edges from the detected edge data; and a base concentration calculating step of subjecting the pixel values in each non-exposure region specified in the non-exposure region detecting step to different arithmetic operations for calculating corresponding base concentrations of the film, whereby the highest of the base concentrations is judged as a true base concentration.
