摘要： An image filing apparatus and method for receiving as multivalue data an image corresponding to a document, converting the data to binary image data and storing the binary image data. According to the features of the present invention, pixels of that portion of an input image corresponding to a particular color are extracted, and luminance data expressing monochromatic binary image data and binary image data designating colored portions are stored in different planes. Not only black pixels but also pixels expressed in a particular color such as red are described in the plane for the luminance data. Pixels having a particular color to be expressed in "red" such as red characters are extracted and recorded as "1" in another particular color plane, for example, in R-plane different from the luminance plane. The R-plane is recorded with binary image data; only pixels written in "red" are expressed as "1" there and other pixels as "0". When outputted, the pixels in which the contents of the luminance plane are "1" and the contents of the R-plane are "0" are displayed in black and the pixels in which the contents of the R-plane are "1" are displayed in red.

摘要： A file document image input can have shading removed to produce a deshaded image that is useful for highly efficient compression encoding, to be thereafter stored and transmitted in such efficient encoded form. When the image is retrieved or received, the decoded and deshaded image may have shading returned to it by combining with a shaded template image stored in the template image memory or by synthesizing shading in specified regions. By removing shading from regions, optical character recognition, shading identification or other processing such as smear prevention can be enhanced.

摘要： Color image processing method and apparatus for suppressing side effects of a chrominance emphasizing process are provided. A chrominance C of an original color image is detected by a chrominance detector. A luminousness V of the original color image is detected by a luminousness detector. A parameter selector selects chrominance conversion parameters on the basis of the chrominance C and luminousness V to generate a selected parameter. A chrominance converter executes the chrominance conversion by chrominance conversion parameters a to i. It is possible to suppress a side effect such that the color deviation becomes conspicuous in a portion of small chrominance and luminousness due to the execution of the chrominance emphasizing process. Thus, image data of a high quality can be obtained.

摘要： A partial region of an image is set as being a secret region and an ID code is put to data concerning this secret region, the data then being stored in a memory, so that, unless an ID code which is input from a keyboard is coincident with the stored ID code, the image is selectively prevented from being displayed on a CRT display, printed by a printer, or subjected to additional writing, revision, cutting on the display screen. Thus, it is possible to restrict the visual output or revision of secret portions of images and therefore possible to individually control images which need to be kept secret and those which need not.
摘要翻译：将图像的部分区域设置为秘密区域，并将ID代码放入关于该秘密区域的数据，然后将数据存储在存储器中，使得除非从键盘输入的ID代码重合使用存储的ID代码，有选择地防止图像显示在CRT显示器上，由打印机打印，或者在显示屏幕上进行额外的写入，修改，切割。因此，可以限制图像的秘密部分的视觉输出或修改，因此可以单独地控制需要保密的图像和不需要保密的图像。

摘要： A compact character string retrieving system capable of producing correctly the result of matching without omission even upon occurrence of multiple matching in which a plurality of search terms are matched for one character string by a finite automation. A destination state for transition brought about by a trailing character of the search term is newly created instead of an initial state. A transition table storage stores the destination state. On the basis of the source state number and a specified pattern character code, the destination state number is read out from the state transition table storage. When the state number read out represents the destination state of the transition brought about by the trailing character of the specified pattern character string, an identifier thereof is outputted. The identifiers of the search terms matched are each represented by one bit information, and a group of corresponding flags is stored in one slot. Multiple matching can be performed without omission. The character string retrieving system is implemented in a reduced size.
