    • In an apparatus for extracting primitive patterns included in an image such as a character or any other figure, the image subjected to primitive pattern extraction is optical multiplied by a multiplier to form simultaneously in parallel a plurality of optical pattern images of a substantially identical shape, and optical correlation calculation between the plurality of optical pattern images and the primitive patterns which are formed in the various types of primitive masks is performed individually and instantaneously, the various type of primitive masks being arranged at a position spaced apart by a predetermined distance therefrom, thereby detecting beams emitted through the various types of primitive masks. Image multiplication, optical correlation calculation between the primitive pattern and the optical pattern image, and transmission of the result of the optical correlation calculation to the photosensors can be simultaneously performed at the light propagation speed. The apparatus structure can be simplified at low cost, and primitive pattern extraction operations can be performed at high speed.
    • 在用于提取包括在诸如字符或任何其他图形的图像中的原始图案的装置中,经过原始图案提取的图像被光乘以乘法器,并行地并行地形成具有基本相同形状的多个光学图案图像, 并且在各种类型的原始掩模之间形成的多个光学图案图像和原始图案之间的光学相关计算被单独地和瞬时地执行,各种类型的基本掩模布置在与其间隔开预定距离的位置处, 从而检测通过各种类型的原始掩模发射的光束。 可以以光传播速度同时进行图像乘法,原始图案和光学图案图像之间的光学相关计算以及光学相关计算的结果的传输到光传感器。 可以以低成本简化装置结构,并且可以高速执行原始图案提取操作。

    • A matrix-vector multiplication apparatus for performing a matrix operation at high speed and in a wide dynamic range, i.e., high precision, wherein an input vector is displayed with radiance of pixels, a display image is replicated into many images through an optical system. Component multiplications and partial summing between rows or columns of the matrix and the input vector are simultaneously performed by a light transmissive mask having transmitance proportional to one digit value of multi-scale (three or more) matrix component and a photosensor. Parallel channels each assigned to a different digit of the matrix component calculates the partial sums and a power-of-m (m is the number of scales) scaling summer connected to the parallel channels electrically produces components of an output vector.
