    • In an image processing method and apparatus, image data having multi-value levels for one pixel is input, and the input image data is quantized such that an output area of one pixel is adapted to an output device in which an output area of one pixel changes depending on the position of the pixel. A quantizing process executes an arithmetic operation based on an algorithm of a neural network on the basis of a value obtained by multiplying an output value by a weight corresponding to an area of each pixel. Therefore, even if pixels have different maximum luminances, the different numbers of bits, and different color expression capabilities, an optimum half-tone process can be performed by an algorithm based on a cellular neural network, and a high-quality image can be obtained.
    • 在图像处理方法和装置中,输入具有一个像素的多值电平的图像数据,并且输入图像数据被量化,使得一个像素的输出区域适合于输出装置,其中一个像素的输出区域 根据像素的位置而改变。 量化处理基于通过将输出值乘以与每个像素的面积相对应的权重而获得的值来执行基于神经网络的算法的算术运算。 因此,即使像素具有不同的最大亮度,也可以通过基于细胞神经网络的算法来执行不同的位数和不同的颜色表达能力的最佳半色调处理,并且可以获得高质量的图像 。

    • Taking into consideration the disadvantage that a large-scale analog neural network cannot be constructed as an LSI and, even if this were possible, the cost would be prohibitive and the network would lack universality, a digital image processor for processing input image data based upon a cellular neural network is provided with a first multiply-and-accumulate arithmetic unit for digitally processing multiplication and accumulation of input image data of a plurality of pixels and input weighting values in a predetermined area, a second multiply-and-accumulate arithmetic unit for digitally processing multiplication and accumulation of output image data of a plurality of pixels and output weighting values in a predetermined area, and a non-linear acting unit for deciding output image data in accordance with results of calculation from the first and second multiply-and-accumulate arithmetic unit and non-linear characteristic parameters. This makes it possible to realize an image processor which excels in universality, ease of control and ease of integration.
    • 考虑到大规模模拟神经网络不能构建为LSI的缺点,即使这是可能的,成本将是过高的,并且网络将缺乏普遍性,用于基于以下方式处理输入图像数据的数字图像处理器 细胞神经网络设置有第一乘法运算单元,用于数字处理多个像素的输入图像数据的乘法和累积以及预定区域中的输入加权值;第二乘法和累加运算单元,用于 数字处理多个像素的输出图像数据的乘积和积累,并在预定区域中输出加权值;以及非线性运算单元,用于根据来自第一和第二乘法运算单元的计算结果来决定输出图像数据, 累积算术单位和非线性特征参数。 这使得可以实现在普遍性,易于控制和易于集成方面优异的图像处理器。
