Abstract
Abstract A film scanner for generating output image data by applying a correction process referring to a predetermined parameter to the read out image data generated by scanning an original is connected to a digital color printer. When an adjustment mode is specified in the film scanner, the reference output image data generated based on scanning a reference original by a printer is fed to the film scanner to be set as the target data. Based on read out image data generated by scanning a reference original having characteristics identical to those of a reference original, a parameter is calculated to be set for a correction process so that output image data matching the reference data is generated.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
114 words
An image system comprising: a scanner for scanning an original image and generating image data; and a printer, detachably interfaced to said scanner by a signal transmission path, for forming an image on a print medium based on the image data transmitted from said scanner, wherein said printer comprises, a memory which stores first reference data expressing a reference image, and a transmitter which transmits said stored first reference data to said scanner by said transmission path, and said scanner comprises, a reference scanning device which scans said reference image to obtain second reference data, and a generator which generates correction data so that said second reference data corresponds to said first reference data.
Claim 2
Dependent Claim
114 words
An image system comprising: a scanner for scanning an original image and generating image data; and a printer, detachably interfaced to said scanner by a signal transmission path, for forming an image on a print medium based on the image data transmitted from said scanner, wherein said printer comprises, a memory which stores first reference data expressing a reference image, and a transmitter which transmits said stored first reference data to said scanner by said transmission path, and said scanner comprises, a reference scanning device which scans said reference image to obtain second reference data, and a generator which generates correction data so that said second reference data corresponds to said first reference data.
Claim 3
Dependent Claim
35 words
The image system according to claim 1, wherein said scanner corrects image data obtained by scanning an original image using said correction data generated by said generator, and transmits corrected image data to said printer.
Claim 4
Dependent Claim
28 words
The image system according to claim 2, wherein said reference scanning device is a scanning unit capable of also scanning an original image to generate original image data.
Claim 5
Dependent Claim
15 words
The image system according to claim 3, wherein said correction data comprises a masking coefficient.
Claim 6
Dependent Claim
16 words
The image system according to claim 3, wherein said correction data comprises a γ correction coefficient.
Claim 7
Dependent Claim
16 words
The image system according to claim 3, wherein said printer comprises a digital color copying machine.
Claim 8
Dependent Claim
95 words
A correction method of correcting image data obtained by scanning an original image with a scanner prior to being transmitted to a printer, comprising the steps of: coupling the scanner to the printer, the scanner being detachably interfaced to the printer by a signal transmission path, transmitting first reference data, representing a reference image, from said printer to said scanner by said transmission path, scanning said reference image in said scanner to obtain second reference data, and generating correction data in said scanner so that transmitted second reference data corresponds to said first reference data.
Claim 9
Dependent Claim
95 words
A correction method of correcting image data obtained by scanning an original image with a scanner prior to being transmitted to a printer, comprising the steps of: coupling the scanner to the printer, the scanner being detachably interfaced to the printer by a signal transmission path, transmitting first reference data, representing a reference image, from said printer to said scanner by said transmission path, scanning said reference image in said scanner to obtain second reference data, and generating correction data in said scanner so that transmitted second reference data corresponds to said first reference data.
Claim 10
Dependent Claim
36 words
The correction method according to claim 7, further comprising the steps of: scanning an original image in said scanner to obtain original image data, and correcting said original image data in accordance with said correction data.
Claim 11
Dependent Claim
105 words
A correction method of correcting image data transmitted from a scanner to a printer, the scanner and printer being detachably interfaced by a signal transmission path, comprising the steps of: transmitting second reference data, representative of a reference image, from said printer to said scanner by said transmission path, scanning the reference image with said scanner to obtain first reference data, comparing said first data and said second data, and generating correction data based upon such comparison, scanning an original image with said scanner to obtain original image data, and modifying said image data in accordance with said correction data, thus generating corrected image data.
Claim 12
Dependent Claim
105 words
A correction method of correcting image data transmitted from a scanner to a printer, the scanner and printer being detachably interfaced by a signal transmission path, comprising the steps of: transmitting second reference data, representative of a reference image, from said printer to said scanner by said transmission path, scanning the reference image with said scanner to obtain first reference data, comparing said first data and said second data, and generating correction data based upon such comparison, scanning an original image with said scanner to obtain original image data, and modifying said image data in accordance with said correction data, thus generating corrected image data.
Claim 13
Dependent Claim
37 words
The correction method according to claim 9, further comprising the steps of: transmitting said corrected image data to said printer by said transmission path, and forming an image with said printer based on said corrected image data.
