摘要： PURPOSE:To extract the basic form features of pictures at high speed by comparing optically an optical pattern image with a basic form pattern. CONSTITUTION:A multiplexing means 4 multiplexing optically the picture from which the basic form features are extracted and forms substantially plural optical images of the same form. The plural types of basic form patterns are produced by a basic form mask 6a from the basic forms contained in common into plural pictures from which the basic form features are extracted and at the same time plural optical pattern images are supplied to the mask 6a in response to plural types of basic form patterns respectively. Thus plural optical pattern images obtained by multiplexing the picture from which the form features are extracted and having substantially one and the same form are optically compared individually and simultaneously with plural types of basic from patterns consisting of the basic forms included in common in plural pictures. Then these results of comparison are detected.

摘要： PURPOSE:To operate the correlation of a picture at high speed by disposing a reference mask at a position separated by a prescribed distance from the image forming surface of an optical pattern image formed by a multiplying means. CONSTITUTION:After an input picture is displayed on a display 1, the picture such as a character to be applied with correlation arithmetic is optically multiplied by the multiplying means 4 to form the plural optical pattern images of the same form. The reference mask 6a is disposed at the position separated by the prescribed distance from the image forming surface 5 of the optical pattern. An optical correlation operation between the multiplied optical pattern image and the reference pattern of the mask 6a and the converging of passing lights from the mask 6a by a converging lens 7 are instantaneously carried out with the propagation velocity of the light. The converged light is detected by a photosensor 8a is parallel with a high speed response characteristic. Accordingly, the optical correlation operation between the input picture and the reference pattern can be executed in parallel and at high speed.

摘要： PURPOSE:To discriminate complicated characters apt to be deformed like hand- written KANJI (Chinese character) and graphics with a high precision at a high speed by distributing respective photodetecting elements to many parallel micro images to arrange them so that their light reception aeas do not overlap one another. CONSTITUTION:An optical sensor array 27 is arranged on the image forming face of a lens array 25, and 256 micro images MI are formed on its surface. The optical sensor array 27 is provided with many strip-shaped (rectangular) optical sensor elements 28 which decompose micro images MI to vertical, horizontal, and oblique character stroke elements to extract them as element features. One sensor element 28 detects positional matching to stroke elements constituting a character image by quantities of received light. Many optical sensor elements 28 are distributed to sensor blocks corresponding to 256 micro images in 1:1 so that they do not optically overlap one another. Thus, hand- written KANJI and graphics are discriminated with a high precision at a high speed.

摘要： PURPOSE:To perform an operation between an input vector and a row or a column of a matrix by processing the rows or columns in parallel with each other via an optical parallel arithmetic channel. CONSTITUTION:An input vector is displayed on a display 25 with light emission of picture elements, and the display image of the input vector is copied in many pieces. Then the multiplication and the addition are carried out between the input vector and a row or a column of a matrix in parallel with each other for each copied image by means of a mask array 34 of the transmitted light quantity showing one of components of a matrix shown in a binary or multi- level form and an optical sensor array 36 which detects the transmitted light quantity. These multiplication and addition are also carried out in parallel with each other for each bit or each digit of a binary code or a multi-level code of a matrix component. Thus a matrix operation is carried out at a high speed and in a wide dynamic range, i.e., with high accuracy.

摘要： PURPOSE:To detect, at high probability, information owned by an incident optical signal by distributing light transmissivity to correspond a transmission factor to the statistical distribution of a light incident position. CONSTITUTION:When a projection characteristic is constituted of scattered projection data a1-an of the total number of (n), the projection data a1-an correspond with respective vector components x1-xn of (n)-dimensional vector x=(x1, x2, x3...,xn) respectively. In order to execute an optical pattern matching with the reference pattern of various kinds of reference masks, respective projection data are quantified to a prescribed quantization level, an (m) stage level, for example, by a digital processing, the quantified projection data are displayed as an optical pattern in a prescribed area corresponding to the vector components x1-xn on a display screen. Thus, even when the incident position of a light to be incident on a prescribed position statistically varies, information to belong to an optical signal can be detected at the high probability.

CONSTITUTION:A vector component corresponding to a projecting feature extracted from an image to be recognized is displayed on a display. In other words, the apexes of strength distribution shown in (a) and (b) are image-displayed 11 as a large number of luminescent line patterns. A multiplication means 14 is constituted of a projecting lens 12 and a lens array 13, and the luminescent line patterns on the display plane of the display 11 are image-formed simultaneously on reference masks 15a respectively. The light quantity of the beam of light passing the reference mask 15a is detected by an optical sensor 17a, and its output is standardized at every reference mask 15a corresponding to the maximum passing light quantity of each reference mask 15a to facilitate the identification of the image. The level of a standardized output is compared at a maximum value detection circuit, and the reference mask 15a on which the maximum output is given is decided. And based on a decided result, the classification and the recognition of the image to be identified can be performed.
