摘要： PROBLEM TO BE SOLVED: To provide an oil detector that is simply configured to eliminate a monitoring burden due to erroneous detection causing light.SOLUTION: An oil film detector comprises: an output signal generation unit for generating an output signal to the outside on the basis of a light-receiving signal of reflected light from a water surface; and an output unit for outputting the generated output signal to the outside. The output signal generation unit compares the light-receiving signal with: a first threshold Lthat is a lower limit value of a light-receiving signal level for detecting an oil film; and a second threshold Lthat is a lower limit value of a light-receiving signal level of erroneous detection causing light. The output signal generation unit generates an oil film detection signal for detecting the presence or absence of the oil film when the light-receiving signal is in a range equivalent to or greater than the first threshold but less than the second threshold; however, it does not generate the oil film detection signal when the light-receiving signal is less than the first threshold or is equivalent to or greater than the second threshold. Accordingly, the oil film detector prevents reflected light or disturbance light from objects other than the oil film from being erroneously detected as the reflected light by the oil film.
摘要翻译：要解决的问题：提供一种油检测器，其简单地被配置为消除由于错误检测引起的光的监视负担。解决方案：一种油膜检测器，包括：输出信号生成单元，用于基于外部产生输出信号来自水面的反射光的光接收信号; 以及用于将产生的输出信号输出到外部的输出单元。输出信号生成单元将光接收信号与作为检测油膜的受光信号电平的下限值的第一阈值L进行比较; 并且第二阈值Lth是导致光的错误检测的光接收信号电平的下限值。当光接收信号处于等于或大于第一阈值但小于第二阈值的范围内时，输出信号产生单元产生用于检测油膜的存在或不存在的油膜检测信号; 然而，当光接收信号小于第一阈值或等于或大于第二阈值时，它不产生油膜检测信号。因此，油膜检测器防止反射光或来自油膜以外的物体的干扰光被油膜错误地检测为反射光。

摘要： PROBLEM TO BE SOLVED: To provide a detector capable of readily performing the positional adjustment and/or calibration work to a detection surface, and to provide a jig. SOLUTION: At positional adjustment and/or calibration of an oil film detector, a target plate 6 and the jig 7 are attached to a hood. When a scanning laser beam L3 advances into the inside 7a of the jig 7 from the opening section 61 of the target plate 6, it is reflected by the detection surface Ws of a container 74. The reflected light L4s projects a predetermined scanning locus on the surface 6b of the target plate 6. The inside of the jig 7 restricts the incidence of the external light of the jig 7. Accordingly, a worker can visually and readily confirm the position of the scanning locus with respect to the opening section 61 via the mirror 8 arranged in a window section 78.

摘要： PROBLEM TO BE SOLVED: To provide a method and a device of observing an image which divides an object area of a color distance image into binary by a single color distance threshold.
SOLUTION: In this image observation method and the device, when an observation object area is extracted by dividing a surface image of an observation object into object areas with similar hue, structure for converting RGB signals of the surface image obtained by picking up the surface image into a numeric value called as a color distance to convert the surface image into the color distance image and dividing the object area of the color distance image into binary by a single set color distance threshold is adopted, though three thresholds are required in a conventional method for decomposing the RGB signals into a luminance signal and a chromaticity signal, performing the image processing of the luminance signal to divide the object area, a single color distance threshold suffices for a threshold, the color distance threshold creates color distance histogram in each object area frame and the color distance threshold suitable for the extraction and division processing of the object area is properly set using an inflection point of the histogram as a guidepost.
