Abstract: In this paper, the design and analysis of the components of an image measuring system based on image analysing is investigated. The authors measured the planar geometrical parameters through image processing and applied these to the "detecting system against registration deviation in color printing" to detect and control the registration deviation online.

Key words: CCD, ROI areas, image processing, registration deviation
