摘要： Any specific color (e.g., flesh-color, sky-blue and so on) is determined for its area on an original color image and corrected by the use of a matrix color correcting factor to assure a high level of reproduction of that color.
Any specific color, for example flesh color, is previously extracted by pre-scanning (S1, S2). An area of the color is determined by counting its pixels included therein (S3). The determined area S of the specific color is compared with a given value C (S4). When S C, another kind of color correction is made (S9, S10). An area of each color is extracted (S9) and a suitable correction factor is selected (S10). All colors are separately corrected by using respectively selected correction factors, that assures a high-quality reproduction of the color image to be printed.

摘要： An image processing apparatus is provided which can output an image from which only specific image information can be positively detected when the specific image information used to prohibit copying of image information is added to image data. The present invention includes a specific image information adding portion (20b) that adds specific image information representing a specific image to image data when image processing is performed for input image data and a specific image information setting portion (20c) that sets a color and/or number of the specific image information.

摘要： An image processing apparatus inputs an image signal obtained by scanning a document in which a character region, a photographic region and a dot region are mixed and stores image data in a local block composed of a target picture element and plural picture elements surrounding the target picture element. The image processing apparatus computes first and second feature parameters P₀ and P₁ representing the features of each region based on the image data in the local block, and inputs the resulting first and second feature parameters P₀ and P₁ to an identification circuit adopting a neural network. The identification circuit outputs the region identification information O₀ and O₁ of the target picture element, and the filter processing circuit performs a spatial filtering process according to the region identification information O₀ and O₁. As described, in the image processing apparatus, since a multi-dimensional identification process is performed using the neural circuit which receives inputs of plural feature parameters, an image identification with very high precision is permitted, and an optimum spatial-filtering process can be applied according to the feature of each picture element, thereby achieving a high quality image.

摘要： In a DMA controller in accordance with the present invention, in the case of memory-to-memory data transfer using the DMA process (transfer for changing addresses inside the memory), one channel for carrying out the data transfer is provided. In the case of data transfer between the I/O device and a memory using the DMA process, two channels for carrying out the data transfer are, on the other hand, provided by using a circuit that constitutes said one channel. Thus, it is possible to provide multiple channels in the DMA controller by using a compact, inexpensive circuit construction.

摘要： In an image processing method, an image is read by an image processing apparatus such as a digital copying machine and the read image is divided into blocks composed of a plurality of picture elements. Thereafter, interpolation is performed on a target picture element so that the image is scaled. Then, in the above image processing method, region segmentation data, which represent possibilities of characters, photographs and mesh dots of the target picture element of the image, are detected in a region segmentation section of the image processing apparatus, and the interpolated picture element data of the target picture element are computed by a variable scaling section according to an equation in which density of a plurality of adjacent picture elements in the vicinity of the target picture element are inputted. At this time, a weights of the density of each adjacent picture element in the equation is adjusted based upon the result detected by the region segmentation means. As a result, even if characters, photographs and mesh dots coexist in an image read by a scanner, the image is scaled according to the characters, photographs and mesh dots, thereby preventing deterioration in image quality.
摘要翻译：在图像处理方法中，图像由诸如数字复印机的图像处理装置读取，并且将读取的图像分割成由多个图像元素组成的块。此后，对目标像素进行内插，使得图像被缩放。然后，在上述图像处理方法中，在图像处理装置的区域分割部分中检测表示图像的目标图像的字符，照片和网格点的可能性的区域分割数据，并且内插图像元素根据其中输入目标像素附近的多个相邻像素的浓度的方程式，通过可变缩放部分计算目标像素的数据。此时，根据由区域分割装置检测到的结果来调整等式中的每个相邻像素的浓度的权重。结果，即使字符，照片和网点在由扫描仪读取的图像中共存，则根据字符，照片和网点对图像进行缩放，从而防止图像质量的劣化。

摘要： The image processing apparatus (data processing apparatus) stores data in a storing unit (storing means), inputs and outputs the data to and from the storing unit via a storage control unit (input-output means) and processes the data outputted from the storing unit with a control unit (processing means). The storage control unit inputs and outputs image data to and from the storing unit by the DMA method through a path via a DMA control unit and inputs and outputs other data such as a control instruction to and from the storing unit by the PIO method through a path via a PIO control unit. Image data to be inputted and outputted to and from the storing unit by the DMA method is encrypted in an input operation and decrypted in an output operation by an encryption/decryption unit provided on the input-output path for DMA method.
