摘要:
An image processing apparatus for converting input color image signals to image recording signals to be sent to an image forming apparatus. The image processing apparatus comprises: a first color converting unit for converting the input color image signals to three-variable color signals independent of devices; a second color converting unit for converting the three-variable color signals to the image recording signals; and a parameter determining unit for determining parameters of the first color converting unit. The parameter determining unit determines the parameters so as to make characteristic colors in the input color image signals coincide with predetermined colors and to maintain linearities of color reproduction characteristics of an output image from the image forming apparatus.

It is made possible to prevent decrease in the density due to the image output characteristic of the image output unit in the subscanning direction by means of a method according to the present invention capable of real-time processing without causing the circuit capacity and the memory to be increased. In an image input unit 100, the input image data is acquired so that its time series direction becomes a direction indicated by an arrow 42 corresponding to the subscanning direction of an image output unit 300. The input image data from the image input unit 100 is corrected in accordance with the image output characteristic of the image output unit 300 in the subscanning direction. The image data after the correction is rotationally processed so that its time series direction becomes a direction indicated by an arrow 41 corresponding to the main scanning direction of the image output unit 300. The image data after the rotary processing is sent to the image output unit 300.

The invention provides an image formation device based on the electrophotographic system, whereby, when an outputted image varies from the halftone area to the background area in the sub-scanning direction, the density reduction of a rear end area of the halftone area that borders on the background area can be prevented, by means of simplified and small-scale processing. In this image formation device, a backward edge of the halftone area that borders on the background area is extracted, and an image data value of the background area including m pixels after this backward edge in the sub-scanning direction, of input image data Si, is modified to a setting value with correction data. The setting value is set to a value slightly lower than the threshold value corresponding to the dot area coverage of an image recurrence start point. If there is a halftone area whose image data value given by input image data Sib is greater than the threshold value, or a background area whose image data value is greater than the setting value, in an area including m pixels in the sub-scanning direction after the backward edge of the halftone area given by input image data Sia, the value of the image data with regard to that area will not be modified, and only the value of the image data with regard to the area from the backward edge of the halftone area to that area will be modified to the setting value.

In view of realizing higher resolution in the sub-scanning direction and achieving high precision and high quality image formation without generating ununiform distribution of exposure, a scanning surface of a photosensitive material is scanned with an optical beam on sequential parallel linear scanning lines with a predetermined angle for the main scanning direction to form an exposed image thereon.

To form an exposed image with striking contrast on photosensitive material and form a high definition and high quality image, a first beam modulated according to an image signal and a second beam modulated according to an inverted image signal generated by inverting this image signal with smaller deelectrification effect than the first beam are synthesized on the photosensitive material.

A system includes an image formation apparatus, an image retrieval server, and image storage servers, and a network for connecting them. The image formation apparatus forms an image based on image data, records the image data in a predetermined storing location on the image storage servers, converts the image data under a predetermined rule to generate an image identification information as a key in order to read the image data from the storing location, and outputs the image identification information. Upon reception of an image data retrieval request together with an image identification information, the image retrieval server determines that the image data whose result of conversion under the predetermined rule is equal to the image identification information, among at least one image data stored in a predetermined storing location on the image storage servers, is the image data to be retrieved, and outputs its information.

An image processing system which reads an image on an original document every pixel by a scanner, processes the read image data, and outputs the processed image data. The image processing system includes a system for recognizing a circular image of a specific color. The recognizing system includes a specific color detecting unit for detecting a specific color on an image on an original document; a first image detecting unit for detecting, in the image detected by the specific color detecting unit, images of the specific color at positions spaced from each other by a first distance corresponding to a diameter of a circle on a line extending in a fast scan direction; a second image detecting unit for detecting intersections of the circle having the diameter equal to the first distance and a line separated by a predetermined distance from a center of the circle in a slow scan direction when the specific color images are detected by the first image detecting unit; and a specific color image determining unit for determining that a contour containing the images of the specific color, detected by the three detecting units, is circular on the basis of the detection of a pitch line of a second distance by the second image detecting unit.
