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.

Monochrome multi-color, and full-color documents are automatically discriminated from each other, and character and photograph regions are also determined in an automatic manner, thereby producing appropriate binary image data according to the operation results. An image data transformation apparatus includes a binarizing section for converting image data inputted thereto into binary image data associated with a plurality of different colors, binary image data buffers for temporarily storing therein the binary image data, a decision section for deciding based on the input image data whether the monochrome, color, or multi-color output is to be produced and whether an intermediate-tone or particular color pixel is to be processed, and a binary image data selection/output section for selecting as output therefrom binary image data according to the decision results.

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:
An image data transfer method and system therefor transfer image data via network 10 connecting between a plurality of clients 100 and a server 400. A plurality of files are stored in image data base storage unit 430 and file search unit 420 searches the files to be processed by desired client from the image data base storage unit 430 in response to the search request of the client 100. The transfer protocol is sorted in transfer protocol storage unit 520 and transfer protocol management unit 150 transmits to a desired client via the network 10 the image data related to the file searched by the file search unit 420 specified the transfer protocol in the transfer protocol storage unit 520 based on the search request of the desired client.
摘要:
A data processor and a data transfer method for efficiently transferring data between a plurality of information processing devices as in a client server system. In case non-coded data such as image data are transmitted, it is necessary to make the transmission management requirements such as protocol, data structure, coding scheme, and coding default condition coincide between the transmitting side and the receiving side. In order to satisfy this requirement, a data processor lying between a plurality of information processing devices and having a data transfer intermediary function records beforehand transmission management information including identification information concerning a plurality of clients, discriminates a client by using the identification information, and recognizes transmission management information concerning the discriminated client. In addition, the data processor analyzes transmission data supplied from the server, on the basis of the transmission management information, and converts it to transmission data conformed to the client.
摘要:
An image processing system which has functions for inputting, storing or receiving, as a binary image data, an image as a document including a photograph having a varying brightness density and of outputting a multi-valued, half-tone image data to a display, a printer or the like, and an image processing method. The system includes a restoration processor. The restoration processor includes a storage for storing therein the binary image data scanningly inputted with use of a window of a predetermined size of m.times.n pixels, a white pixel number detector for detecting the number of white pixels in the binary image data within the window, a plurality of calculators for performing multiplication/accumulations operation over the binary image data within the window and a predetermined coefficient matrix to provide a plurality of multi-valued image data, and a selector for selecting one of the plurality of multi-valued image data found by the plurality of calculators.
摘要:
An apparatus for document browsing, specifically for document retrieval systems. The browsing apparatus enables users to see multiple document pages on the same screen at the same time in a first mode and to see a bundle of pages on a screen in a second mode. The images shown on the screen are produced internally according to the user's commands. The pages may be flipped in either direction and selected pages may be marked for later printing instructions.
