Abstract:
An image inputting method for use in printed matter inspection of a printing condition of a pattern printed on a running original piece (W) by a print drum, in which a partial image of said pattern is input by a partially inputting camera which is capable of being moved in a width-direction of said original piece by a moving mechanism, said method comprising the steps of:inputting a whole image including the whole pattern by a wholly inputting camera disposed apart from said partially inputting camera by a predetermined distance in a direction in which said original piece (W) flows; coordinating, based on a relationship between a position, on said whole image, of said partial image which is capable of being input by said partially inputting camera and a width-directionwise reference point (S) set on said whole image, the width directionwise position on said whole image and the width-directionwise position on said moving mechanism with each other, when said partially inputting camera is located on an origin set on said moving mechanism; positioning and then setting a photographing point, which is to be input by said partially inputting camera, on said whole image; calculating a width-directionwise pixel number between said set photographing point and said width-directionwise reference point (S) on said whole image; multiplying said calculated width-directionwise pixel number by a width-directionwise resolution of said whole image to calculate the width-directionwise moving amount on said moving mechanism; moving said partially inputting camera up to a target position corresponding to said width-directionwise moving amount; and inputting said partial image at an arbitrary timing by said partially inputting camera moved up to said target position.
