  • Page 372 Glossary Ë Expansion and contraction to eliminate binary noise in the image When an image is converted to black and white, a number of unwanted dots may appear in the image. These noises can be eliminated during the preliminary processing. Dot control processing of binary val- ues is used to eliminate this problem, as described below.
  • Page 373 Gray scale check using the normalization correlation method Even when the IV-S20 is looking at the same object as the object used for the reference image, the new target image and the previously stored reference image may not match completely, due to variations in the illumination conditions and the ambient light.
  • Page 374 Glossary Ë Gray scale search (corrected gray scale search) The "gray scale search" function is a system for detecting a point where the input image and the refer- ence image match, after calculating the matching levels in the input image and the reference image. [Procedures] 1 Store the reference image as a gray scale image with 256 levels of gray.
  • Page 375 Ë Normalization correlation To determine whether the levels between the reference image and the input image match, the IV-S20 uses an information processing method called "normalization correlation." This is a method used to cal- culate relationship between two groups of data.
  • Page 376 (e. g.: 120 horizontal lines) can take only 25 % of the time to read the entire image. The IV-S20 can automatically determine the width of the partial image window. You can change back and forth between reading the whole image and a partial image.
  • Page 377 In order to make a partial reading of the CCD image at high speed, the IV-S20 is equipped with the detection function described above with the works just like a proximity sensor to trigger the CCD. A proximate sensor can also be connected to the system.
  • Page 378 - A "pixel" is one picture element (DETECT ACCURACY: STANDARD (detection precision: standard) in case of the IV-S20). "Sub pixel" refers to a unit smaller than a single pixel (DETECT ACCURACY: HIGH (detection precision: high) for 1/10 pixel in case of the IV-S20).
  • Page 379 Threshold value setting The IV-S20 treats the "areas darker than the lower limit value" or "brighter than the upper limit value" as "black." It treats that the areas between the upper limit value and lower limit value as "white." However, if the white-black reverse function is enabled, conversion to white/black will be reversed.
