It is decided whether only the format field of an A column of the table 1 is set, and when only the format field is set, parameter setting table coloring processing that classifies data types of each cell of the table 1 is performed based on the original 2 which is set in the format field. When not only the format field is set, program creation processing for image display that creates a program 3 for image display is performed based on the original 2 that is specified with the format field and the table 1.
