<P>PROBLEM TO BE SOLVED: To remove influences by an irregular density variation caused in a process such as a light exposure step or a developing step upon creation of a 3-dimensional lookup table for the purpose of signal conversion of a relationship between an exposure control value and a color of an output image with use of an image output device for recording an image in a silver halide photosensitive material for movie by an optical means. <P>SOLUTION: In a method of removing a density variation in a 3-dimensional lookup table for image signal conversion, a neutral gray area is located in an exposure pattern for creation of a 3-dimensional lookup table, a density variation irregularly occurring is corrected on the basis of the density variation quantity of the neutral gray area, thus increasing a reproduction accuracy for color signal conversion. <P>COPYRIGHT: (C)2010,JPO&INPIT |
