摘要： In an image editing apparatus, an image input section inputs an original image. A processor section compresses the input image and stores the compressed input image as an image file in a memory section. The processor section decompresses the image file that is stored in the memory section, and executes a layout analysis process and extracts layout information. Based on the layout information obtained by the layout analysis process and a prescribed rule, the processor section executes rearrangement of layout. Image information, which includes the rearranged information and layout information before and after the rearrangement, is stored in the memory section as a file.

摘要： A color multi-function type copying machine is disclosed which includes an image input unit for optically sensing an input image and generating an image signal. A function memory stores an ink color used in a color frame to be written in the input image in order to designate its partial image region and a specific image edit function assigned to the ink color and desired to be executed by an operator so that the ink color and the specific image edit function can be rewritten. When a closed loop-like color frame of a selected color is written in the input image, a color frame region detecting unit detects a shape and a color of the color frame. In response to the detection result, the memory is accessed to determine an image edit function corresponding to a first selected ink color of the detected color frame. A color edit unit executes one or a plurality of image signal processing corresponding to the determined image edit function for the input image signal. The edited image signal is supplied to a color printing unit via a signal processing unit and is reproduced therein.

摘要： A color copying machine has a scanning-type proximity linear image sensor unit for optically scanning an input image and producing an image read signal, and a color printer unit for producing a copy image corresponding to the input image at limited levels of printing density. An image type discrimination circuit receives the image read signal, and at least partially discriminates the type of image based on a pattern matching technique, thereby producing a discrimination signal for specifying the image type in a pixel region of a predetermined size of the input image. An adaptive signal processing circuit also receives the image read signal, and performs different image signal correction processing in accordance with the discriminated image type, thus producing a corrected image signal, which is supplied to a multi-value dithering processor. The multi-value dithering processing circuit performs multi-value dither processing of the corrected image signal, and produces a printer drive signal for defining a printing pixel pattern for each pixel of the input image.

摘要： According to one embodiment, a color correction apparatus includes an input portion, a storing portion and a correction portion. The input portion inputs color image signals which correspond to recording color material amounts. The storing portion stores a standard color reproduction parameter for calculating a standard color reproduction chromaticity and reference chromaticity deviation amounts at a plurality of reference color points in recording color material amount coordinate space. The correction portion estimates chromaticity deviation amounts of the input color image signals on the basis of the reference chromaticity deviation amount, calculates a standard chromaticity which corresponds to the input color image signals on the basis of the standard color reproduction parameter and corrects the input color image signals on the basis of the estimated chromaticity deviation amounts and the standard chromaticity.

摘要： There is disclosed an image processing apparatus in which a pattern table stores a plurality of screen patterns which include a predetermined number of pattern data and have different data patterns. An in-pattern position calculator generates an in-pattern position signal indicating a position of an input image signal in the screen pattern from main and sub scanning synchronizing signals. A pattern selecting signal combining section generates a pattern selecting signal for selecting a specified pattern in the pattern table from the input image signal, combines the pattern selecting signal and the in-pattern position signal supplied from the in-pattern position calculator, and supplies an address in the pattern table. A controller reads pattern data corresponding to the address in the pattern table from the pattern table and supplies image data.
