Title: Detector for density variance
Inventor: OZAKI NOBORU
IPC: H04N7/18
Filed: 1984-09-12
Abstract: PURPOSE:To ensure stable detection for the presence/absence or the scale of density variance by dividing an image to undergo the detection of the density variance into prescribed areas and excluding the divided areas having the small distribution width with the image forming picture element part of the density histogram. CONSTITUTION:An image stamped on a prescribed stamping surface of an IC element through an observation part 1 is divided equally into 16 square areas by an address designation part 3 and a histogram memory 4. Then the density histogram is produced for each picture element of each divided area, and only the divided area having the distribution width larger than a certain value with the image forming picture element part on each density histogram is designated as an area to be detected for density variance by a distribution width calculation part 6 and a detection area 7. A mean density calculation part 8 obtains the mean density Ai of the image forming picture elements for each of K (<=16) pieces of divided areas which are designated as the areas to be detected for density variance. While a density variance exponent calculation part 9 calculates the density variance exponent F from an equation I. A deciding part 10 compares the exponent F with the deciding reference value to decide the presence/absence of the density variance with a stamped image to be checked. Thus the stable result of detection is obtained regardless of the ambient conditions including the illumination, etc.
