An apparatus for inspecting the characters/numbers of a negotiable instrument, the apparatus being provided with: cameras () for imaging the character/number sequence () printed on each design on large-size printed matter () on which a plurality of designs of the negotiable instrument are printed; and a character/number inspection device () for determining the suitability of the characters/numbers printed on each negotiable instrument on the basis of the image data imaged by the cameras (), wherein the character/number inspection device () determines the suitability of the character/number sequence () in a cut segment () on the basis of a plurality of determination standards set in accordance with the position of the cut segment () on the large-size printed matter ().

Provided is a method for removing character background in a color image that obtains an image for printing evaluation by removing a background design of a character from the color image of a printed object on which the character has been printed. The method includes separating a color input image into a character part and a background part, calculating a discriminant function for separating pixels of the character part and pixels of the background part based on pixel values, and generating a background-removed image by removing the background part from the input image by using the discriminant function. Moreover, an installation adjustment method of a line camera including adjusting, based on a signal acquired by capturing an installation adjustment chart fixed to the inspection drum, an installation position of the line camera that acquires an image of a large-size printed object arranged on an inspection drum, is executed by using an installation adjustment chart wherein a plurality of patterns formed by white background and black vertical lines are arranged by shifting in a vertical direction so that the vertical lines continue horizontally only in a predetermined rectangular region that is elongated in a scan line direction of the line camera.

It is controlled by a non-transformation coefficient calculated by a non-transformation calculation section, whether feedback is performed or not. When the feedback is ended, a collation value calculation section calculates a collation value (coincidence coefficient&#xd7;non-transformation coefficient). A display process section compares the collation value with a predetermined threshold value. When the collation value is a threshold value or more, a signature is decided as a true signature, and the transformation-corrected image and the reference image are displayed such that these images overlap.
