摘要:
This invention provides the following environment. That is, an original document file corresponding to a document to be copied is specified from image data of that document to be copied, and a print process is made based on the specified file so as to prevent deterioration of image quality. Also, when a document to be copied is not registered, a registration process is executed to suppress deterioration of image quality in an early stage. Furthermore, since the document is converted into vector data, re-use of such document is facilitated, and deterioration of image quality can be suppressed even when an image process such as enlargement or the like is made. To this end, when an original digital file cannot be specified, an apparatus of this embodiment executes a vectorization process (S54), converts the obtained vector data into a data format that can be re-used by an application (S55), and registers the converted file in a file server (S56). With this registration process, since the location of the file is settled, that location information is composited on an image to be scanned using an identifier such as a two-dimensional barcode or the like (S48), and the composite image can be printed (S49). Even when the printed document is scanned again, a registered digital file can be easily specified.
摘要:
In a copying machine connected to the network, calibrations on the printers are performed as follows. When an execution of calibration is requested, the copying machine displays all identification numbers of the printers connected to the network on the operation panel of the copying machine. When the user selects a printer to be calibrated through the display, the copying machine causes the selected printer to output a specified test pattern. Then the copying machine reads the test pattern, generates a correction table and registers the generated table with the printer.

An image conversion apparatus for image-converting input color image signals, and outputting the converted signals to an output apparatus, allows execution of a plurality of different color processing operations, checks if an input color image falls within a color reproduction region of the output apparatus, and changes the color conversion processing result to be output depending on whether or not the input color image falls within the color reproduction region of the output apparatus. For example, when the input color image falls within the color reproduction region of the output apparatus, color reproduction color-matched with input color image signals is performed. When the input color image falls outside the reproduction region, color reproduction is performed by color conversion processing assuring highest color reproducibility.

A color image reading system in which an input color image signal is converted into color data signals. The color data signals are indicative of a combination of data of reference stimuli represented by vertices of a triangle of which one side circumscribes a pure purple locus, and of which the remaining two sides circumscribes two points of a spectral locus of a color degree diagram, the two points representing substantially middle colors between a color represented by one vertex of the triangle at which the remaining two sides intersect and each of two colors represented by the remaining two sides of the triangle, respectively. The input color image signal is reproduced on a color image output device in response to the provision of the color data signals.
摘要:
An image forming apparatus has a detector for detecting an image density of an original, a processing unit for forming an image, and a control unit for controlling an image forming condition of the processing unit. The control unit non-linearly controls an output thereof in response to a change of the original density detected by the detector.

摘要:
A color image processing system for performing undercolor removal. The system includes input of a color image signal, generation of a grayness signal from the color image signal, generation of a darkness signal from the color image signal, and performance of undercolor removal based on the grayness signal, the darkness signal, and a black signal corresponding to the color image signal. The system also includes control of an amount of undercolor removal performed on the color image signal so that a gradient of an amount of undercolor removal performed on the color image signal relative to the grayness signal at a first darkness signal level is lower than a gradient of an amount of undercolor removal performed on the color image signal relative to the grayness signal at a second darkness signal level, wherein the second darkness signal level is lower than the first darkness signal level.
摘要:
For the expression of a foreign gene, a virus is provided in which at least a part of a cysteine protease gene present on a genome of a baculovirus has been deleted or substituted by a marker gene. A process is also disclosed for the formation of the virus. A transfer vector for the deletion of a cysteine protease gene is also described. This transfer vector comprises a DNA fragment of a nuclear polyhedrosis virus genome, in which at least a part of a cysteine protease gene has been substituted by a marker gene, and a plasmid vector fragment. Also disclosed is a process for the production of an economic protein. This production process comprises inoculating a host insect with a gene recombination virus, said gene recombination virus having been obtained by deleting or substituting by a marker gene at least a part of a cysteine protease gene present on a genome of a baculovirus or a nuclear polyhedrosis virus; expressing an economic protein gene inserted downstream a polyhedral gene promoter, granulin gene promoter or p10 gene promoter of the gene recombination virus; and collecting the economic protein.
