A teaching device constructs, in a virtual space, a virtual robot system in which a virtual 3D model of a robot and a virtual 3D model of a peripheral structure of the robot are arranged, and teaches a moving path of the robot. The teaching device includes an acquisition unit configured to acquire information about a geometric error between the virtual 3D models, and a correction unit configured to correct the moving path of the robot in accordance with the information acquired by the acquisition unit.

This invention allows both a plateless textile printer that makes process color expression, and a plate textile printer to achieve equivalent color expressions. For this purpose, image data that uses an RGB pallet is converted into YMCK image data using a correction table. An ink-jet textile printer ( ) prints on textile on the basis of the converted image data. On the other hand, the image data that uses the RGB pallet is sent to a plate separation data generation unit ( ), and is separated into binary plate data, the number of which is the same as the number of ink colors of the ink-jet textile printer, using an RGB/ink color tone correction table to realize the same color expression as that of screen textile printing. In this case, a plate data file name to be generated, the resolution of a plate to be output, the number of repetitions of an original design of plate data to be output in the horizontal direction, and the number of repetitions of the original design of the plate data to be output in the vertical direction are respectively input to boxes ( ) on a dialog. Also, an input conversion file, an output conversion file, a tone curve file used by retouch software, an original image resolution, an enlargement/reduction method, an ink table file, an output data type, and a repetition method are respectively selected using pull-down menus ( ) of the dialog. Using these parameters, a film plotter ( ) prints images in units of plates (colors) on lith films, and the printed lith films are set in an exposure machine ( ) to undergo exposure, thus obtaining all plates. Using the obtained plates, a screen textile printer ( ) prints on textile using the same inks as those of the ink-jet textile printer.

Textile printing system, and plate separation apparatus and method

An image processing method and apparatus employing a cyclic error diffusion method for binarizing a basic image represented by multivalued data, in order to form a high quality image represented in pseudo tones with reduced noise caused by the binarization. When each pixel is sequentially binarized by applying the error diffusion method to the basic image, errors generated at one edge of the basic image are incorporated into the edge of the other side, and error diffusion is performed while incorporating the errors. Furthermore, a supplemental image, which is a part of the basic image, is added to the upper edge of the basic image to form a combined image, and the error diffusion processing is performed by utilizing the combined image. Upon completing the binarization processing, binary data in the lower edge portion of the supplemental image is compared with binary data in the corresponding lower edge portion of the basic image, and pixel values in the area are corrected based on the comparison result.

Image processing apparatus and image processing method

An image processing system is constructed of an input device for inputting color image data which does not include color components corresponding to specific colors' a storing media for storing a table for making the color image data which does not include the color components corresponding to the specific colors correspond to output image data constructed of color components corresponding to the plurality of recording materials including the specific colors' and a developing unit for developing the input color image data into output image data constructed of the color components corresponding to the plurality of recording materials including the specific colors by using the table. The developing unit executes the developing process by using an interpolating process according to the kinds of color components corresponding to the recording materials. A precision of a color reproduction by a plurality of coloring materials including specific colors is raised by performing an interpolating process according to the color components.

Image processing system and method and recording media

A facsimile apparatus has a transparent plate on which a document may be located. The document is then scanned by a scanner which includes electronic solid state light generation means e.g. LEDs which illuminate the document, with the light reflected from the document being detected by a detector. An electronic signal corresponding to an image of the document may then be transmitted to a remote location. Alternately, the facsimile apparatus may be used to copy the document. Cut paper sheets are withdrawn from storage and an image printed thereon by a heat transfer system in which a film of ink is selectively heated. Paper on which an image has been printed is then received on the upper surface of the storage. The facsimile apparatus may also have a document transporter for moving a document past the scanner with the scanner fixed.
