摘要： PROBLEM TO BE SOLVED: To provide an optical information processing system which performs pattern recognition precisely at a high speed and an image parallel light input device which can store input image information in a semiconductor storage element in a short time. SOLUTION: This system is equipped with a reflection type image input means 5 which stores an input image of the optical information processing system for pattern recognition and reflects 1st read light, a split irradiating means which emits the 1st read light in the opposite direction from the direction where the input image is inputted and converges it on the input means 5 through a Fourier transforming lens 3, a means which performs multiple correlation operation between the input image included in the 1st read light that is reflected by the input means and travels through the Fourier transforming lens 3 and a discrimination pattern, a correlation image composing means which composes one discrimination pattern image of multiple correlative images included in 2nd read light that travels in the opposite direction from the direction of the correlation operation and is transmitted through the said Fourier transforming lens, and an optical detecting means 9 which stores the composite discrimination pattern image in a semiconductor storage element.

摘要： PURPOSE:To provide a high-grade recognition function by providing a spatial identification filter array and a lens array in a correlative optical system and a weight mask in a multiplex image-forming system via a nonlinear respondent. CONSTITUTION:The correlative optical system is provided with the spatial identification filter array with the lens array, and several featured values in a material body to be identified are arranged in patterns of different size in the identification filter array, respectively. When all the featured values are detected. it is recognized that an object material body with size equivalent to that exists. The multiplex image-forming system provided with the weight mask is arranged at the rear stage of the correlative optical system via the nonlinear respondent. In this way, the high-grade recognition function can be provided.

摘要： PURPOSE: To visualize the blood distribution over an inspection surface by image-picking up reflected light from the surface of a specimen with an image- pickup device equipped with a filter to irradiate with the light of a specific wavelength the surface and allow the transmission thereof. CONSTITUTION: Light of 430nm wavelength band is projected to a specimen surface A from a light radiation device 1. Then, the light reflected from the surface A is photographed with an image pickup device 2 and visualized on a monitor 3. In this case, a filter for allowing the transmission of a wavelength band between 428nm and 449nm, an image intensifier capable of sensing a wavelength band of 430nm and a visualization CCD camera are, for example, used as the device 2. Thereby, the distribution of oxygenated hemoglobin over skin surface can be visualized.

摘要： PURPOSE: To determine the adhering state of moisture visually regardless of the temperature of an object by irradiating a surface to be inspected with a light of a specified wavelength band and capturing the light reflected thereon by means of an image pickup unit sensitive to the light in that wavelength band. CONSTITUTION: A surface A to be inspected is irradiated by an irradiation unit with infrared rays of a wavelength band in the range of 1.9-2.4μm where the moisture absorbs the light strongly. The reflected light is passed through a filter for passing the light of the same wavelength band, captured by an image pickup unit 2 comprising a combination of an infrared camera sensitive to the same wavelength band and an optical lens for visible light and visualized on a monitor 3. The filter may cut a wavelength band of about 3μm or above or about 2.4μm or above emitted from an object at normal temperature. This arrangement can eliminate the effect of light radiated from the object in the vicinity of normal temperature and the distribution of moisture can be inspected accurately. Consequently, physiological or psychological reaction in the form of perspiration can be measured or studied and the comfortableness of clothes at the time of perspiration can be evaluated.

摘要： PURPOSE: To precisely perform pattern recognition even when a body to be recognized differs in lightness with areas by performing both correlating operation for detecting a lightness distribution and correlating operation for detecting a pattern to be recognized through two correlative optical systems. CONSTITUTION: This device is equipped with a double image formation systems 10 facing a body A to be inspected, and the correlating optical systems 20 and 30 are arranged behind the system 10 across a spatial optical modulator 40. The optical system 20 performs the correlating operation for detecting the lightness distribution of the body A to be inspected and the other optical system 30 performs the correlating operation for detecting the pattern to be recognized on the body A to be inspected. The lightness distributions of obtained correlative images are inverted by a correlative image inversion optical system 50 and put together. A threshold process is performed for the composite image to select only peaks which exceeds the threshold value, and the clear peaks are obtained. Those peaks accurately reflect the correlation to the pattern to be recognized irrelevantly to differences of the lightness distribution between the input images.

摘要： PURPOSE:To facilitate the real time processing by using a correlating filter having plural standard patterns and a display filter having a prescribed display pattern and circulating input light through a correlation optical system and a display optical system. CONSTITUTION:With respect to a correlating filter 5, filter generating patterns having prescribed relations are synthesized to generate respective standard patterns and these patterns are arranged on the correlating filter 5. With respect to a display filter 10, one of filter generating patterns used for synthesis of respective standard patterns is provided correspondingly to arrangement of each standard pattern. The input light from a pattern to be recognized is circulated through the correlation optical system and the display optical system. Thus, the search operation of a maximum peak value is unnecessary to easily perform the real time processing at the time of recognition and display of the pattern.
