Abstract: PROBLEM TO BE SOLVED: To improve an image forming method and an image forming device for automatically correcting the deviation of image elements with a regular copy operation. SOLUTION: In a digital copy machine 1, an image processing part 13 is provided with a recognition part 3, an image correction part 32 and an adjusting pattern addition part 33. At the time of forming the image, the adjusting pattern addition part 33 forms an adjusting patter 4 in a blank part 7 which is out of an image area. When a recording sheet 5 where the adjusting pattern 4 is formed is copied as an original, a reader 11 reads the adjusting pattern 4 and the recognition part 31 recognizes the position of the adjusting pattern 4. When the recognition part 31 recognizes the adjusting pattern 4, the image correction part 32 adjusts correction data. When an image forming part 12 forms the image, the deviation of the image is corrected. Then, the adjusting pattern addition part 33 adds the adjusting pattern 4 in the part out of the image area.

Abstract: PROBLEM TO BE SOLVED: To provide an image forming device capable of simplifying the inputting operation of a color which has to be extracted, when converting a read image to an image of a different color and outputting it. SOLUTION: A digital color copying machine reads a color original to form a color copy. A specific term related with an image part being the object of the color original to be read is inputted by using an operation panel 49. An image of the object of a color component related with the term is image formed with a specific color image by a control part 55, a table 54, a comparing part 53, a color conversion part 52 and an image forming part 210, and outputted. The image of the remaining color components is image-formed with a color image of a single color different from the specific color and outputted.

Abstract: PROBLEM TO BE SOLVED: To reduce a working time for setting each input and output characteristic value in an image formation device provided with multiple input and output characteristic values. SOLUTION: An image data input section 40 that reads an original as image data is provided. A target value memory section 3 that stores a target value for an input and output characteristic value when a standard original 2 is read is provided. A comparison section 3 that generates a new input and output characteristic value, comparing image data of the standard original 2 with the target value is provided. A fixed value memory section 4a that stores as a fixed value a difference between an input and output characteristic values of an original and that of a copy is provided. An adding section 4 that adds the fixed value to the image data of the standard original 2 and outputs the result to a comparison section 3 is provided. Multiple input and output characteristic values can be set by reading only at a time the standard original 2 because the fixed value memory section 4a and the adding section 4 are provided.

Abstract: PROBLEM TO BE SOLVED: To compensate chromatic aberration with accuracy by seeking information of chromatic aberration from image data in an actual use. SOLUTION: By using a reference manuscript having a pattern with white and black lines arranged alternately, image data for each color of RGB is collected by reading the pattern of the reference manuscript. A reference point in the scanning direction for each color is determined from the image data. A dislocated amount from another color with the reference of R is calculated to be used as a compensation value of chromatic aberration. The chromatic aberration of the image data obtained from reading the manuscript is compensated on the basis of the compensation value.

Abstract: PROBLEM TO BE SOLVED: To prevent a reference member from getting a taint damage and reads the reference member in the same state as that when an original image is read so as to accurately correct shading at all times. SOLUTION: A reference sheet 5 is wound and stored on a circumferential face of a winding roller 4 whose shaft is supported at a downstream side of a platen roller 3 in an original carrying direction and by turning the winding roller 4, the reference sheet 5 is made to feely move between an escape position and an exposed position with respect to an original read position P located between the platen roller 3 and a contact glass plate 21. In the case of reading an original image, the reference sheet 5 is wound on the circumferential face of the winding roller 4 to be located at an escape position and only at reading of shading correction data, the reference sheet 5 is exposed at the original read position P so that shading correction data are read from the reference sheet 5 in the same state as that as reading of the original image. Furthermore, the reference sheet 5 is not in contact with an original D so as to prevent the reference sheet 5 from getting dirt.
