Setting Measurement Conditions (2) Threshold value setting The IV-S30J 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. Normally, if you want to use only one threshold value for binary conversion, set the upper limit value to "255.

Setting the Conditions for Each Object Type Contraction Expansion Binary conversion (6) The expansion/contraction method of eliminating noise in binary images When converting an image to binary values, it is often the case that dots of noise will show up in the converted image. This noise may be eliminated during pre-processing by using the smoothing function. However, it can also be dealt with through the expansion/contraction noise elimination method.
PAGE 61
Setting Measurement Conditions (7) Edge detection The "edge" refers to the boundaries between the brighter (white) and darker (black) parts in an image. The "edge detection" function is used to detect this boundary by processing the image.

Setting Measurement Conditions (9) Contrast search in the reference image Using the reference image area setting in the gray scale search mode, the area of maximum contrast can be identified automatically in the captured image. - While moving the selected reference image area within the specified search area on the captured image one pixel at a time, the IV-S30J determines the density in each area in the reference image, and automatically picks the area with the largest difference.

Troubleshooting Chapter 19: Troubleshooting Item [1] shows problems which may occur when the IV-S30J measurement system is started. If any error (the termination code is not 00 (H)) occurs during image processing on the IV-S30J, take the steps described in item [2]. Perform the recommended daily inspection following the maintenance procedures listed in item [3]. [1] Symptoms and checks The following symptoms may not be malfunctions. Before asking us to repair your equipment, check the recommended parts.
PAGE 296
Troubleshooting Phenomenon Checks 1. Make sure that the communication cable has been correctly connected. 2. Make sure that the communication cable route does not run near electrically noisy devices. 3. Make sure that each terminal of the camera cables is properly connected. Communications through a computer link cannot be established. 4. Make sure that the communication conditions (standard, speed, and parity check) in the personal computer conform to those of the IV-S30J. 5.

Troubleshooting [2] Causes of termination codes (when an error occurs) and remedies When an abnormal termination code (other than 00(H)) is received, take the following measures. Termination code (H) Cause Remedy Processing errors Hardware errors Computer link errors Communication errors 01 The specified processing code does not exist. The wrong number of data items was specified 02 in the text. 03 The text data is outside the acceptable range. Check the processing code.

Troubleshooting [3] Maintenance Check the equipment for the following items. (1) Operation check - Change the measurement number on the MAIN OPS MENU, and change the monitor screen to the freeze or through mode. Then, make sure that the image is normally displayed. (2) Checks - Check the illumination from the lighting equipment. - Make sure that the monitor screen is in focus and that the aperture setting is proper.
