PROBLEM TO BE SOLVED: To provide a test print, an exposure device and a method of correcting the exposure device in which a shading correction is efficiently performed at a low cost. SOLUTION: A photograph processing apparatus 10 is provided with an exposing unit 28 which exposes and forms a picture on photographic paper S, and a picture 101 for detecting shift quantity is exposed and formed on the photographic paper S with the exposing unit 28 to produce the test print 100. The picture 101 for detecting the shift quantity of the test print 100 includes a reference picture 102 and comparison pictures 104a and 104b. The reference picture 102 is a strip picture having a predetermined color developing density extending in the direction of an arrow A. The comparison pictures 104a and 104b are extended in the direction of an arrow B with respect to the reference picture 102, and composed into belt-like scale picture in which the color developing density increases gradually by arranging patches P1 to P15 having the same color as that of the reference picture 102 in the direction of the arrow A. The test print 100 is used for shading correction. COPYRIGHT: (C)2007,JPO&INPIT |
