Abstract

PURPOSE:To conduct precise and stable optical density measurement by a method wherein a measuring device scans a unit checking area of an object to be checked and measures a checking density in accordance with an image density detection format set by a measurement control device and the result of measurement is subjected to arithmetic processing. CONSTITUTION:In accordance with checking items shown by an external signal input device 72, a measurement control device 73 sets the position and kind of a pattern to be checked and the procedure of checking processings. A pattern information storage device 74 stores the pattern to be checked inside the object to be checked, and a processing procedure storage device 75 stores the checking processing procedure for the pattern to be checked. A measuring device 76 moves to the position 87 of a representative point specified by the device and detects an image density, an object of measurement, thereat in accordance with an image density detection format. The result of detection is outputted as a density data string 91 to an arithmetic processing device 78, which executes a corresponding arithmetic processing on the basis of an arithmetic processing code 89 supplied beforehand from the device 73 and outputs the result through an output device 83.
