PURPOSE:To obtain high-accuracy data by taking sample measurement of print, etc., after measuring absolute white and relative white, and then processing the result automatically. CONSTITUTION:An image formation part 10, a computer part 20, an image processor 30, etc., are provided. Then, a form whose print quality is to be measured is fixed on the fixed table 11a of an X-Y stage 1 and the fitting rack 11b of a CCD camera 12 is moved in an X-axial and a Y-axial direction to detect an image within a desired range to be measured. In this case, the range is adjusted finely by using X- and Y-axial fine adjusting handles 11c and 11d. Further, X-axial and Y-axial liner scale counters 13 and 14 outputs the displacement quantities of the axes as digital values to a subcontrol box 16. The box 16 is controlled with an operation switch 17. The computer part 20 stores its internal memory with data inputted from the formation part 10 through the processor 30 and performs automatic arithmetic processing according to a prescribed equation after the end of the measurement. Thus, the high-accuracy data is obtained. |
