Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
99 words
An image processor for generating original image data expressing an original image (31), characterised in that the image processor comprises image data storage means (52) for storing image data expressing respective density levels of reference points (P) which are arbitrarily selected on said original image (31), correction means (54, 56, 58) for correcting said image data according to an image correction rule stored in said image processor through a setting-up process, thereby to provide corrected image data expressing respective corrected density levels of said reference points, and visual means (64) for simultaneously visually indicating said respective corrected density levels.
Claim 2
Dependent Claim
99 words
An image processor for generating original image data expressing an original image (31), characterised in that the image processor comprises image data storage means (52) for storing image data expressing respective density levels of reference points (P) which are arbitrarily selected on said original image (31), correction means (54, 56, 58) for correcting said image data according to an image correction rule stored in said image processor through a setting-up process, thereby to provide corrected image data expressing respective corrected density levels of said reference points, and visual means (64) for simultaneously visually indicating said respective corrected density levels.
Claim 3
Dependent Claim
31 words
An image processor in accordance with claim 1, wherein said visual means (64) has an image display on which said corrected density levels are displayed together with said original image (31).
Claim 4
Dependent Claim
27 words
An image processor in accordance with claim 2, wherein said corrected density levels are displayed at respective neighbourhoods of said reference points on said image display (64).
Claim 5
Dependent Claim
48 words
An image processor in accordance with claim 2, wherein said corrected density levels are displayed at a predetermined position on said image display (64) together with respective reference symbols, and said reference symbols are displayed at respective neighbourhoods of said reference points (P) on said image display (64).
Claim 6
Dependent Claim
32 words
An image processor in accordance with any one of claims 1 - 4 wherein said visual means (64) has a plurality of density indicator units (74) for indicating respective corrected density levels.
Claim 7
Dependent Claim
41 words
An image processor in accordance with claim 5, wherein said image processor is a colour image processor, and each of said indicator units (74) has a plurality of density indicators corresponding to respective colour components included in said corrected image data.
Claim 8
Dependent Claim
19 words
An image processor in accordance with claim 6, wherein each of said density indicators has a density meter (76).
Claim 9
Independent Claim
117 words
A method of setting up an image processor, in which an original image (31) is prepared characterised in that the method comprises the steps of arbitrarily selecting a plurality of reference points (P) on said original image (31), obtaining density data expressing respective density levels of said reference points (P), correcting said density data according to a predetermined image correction rule, to obtain corrected image data expressing respective corrected density levels of said reference points (P), visually indicating said respective corrected density levels on visual means (64) simultaneously, and adjusting said image correction rule to a desired correction rule while monitoring said respective corrected density levels indicated on said visual means (64), thereby setting-up said image processor.
Claim 10
Independent Claim
117 words
A method of setting up an image processor, in which an original image (31) is prepared characterised in that the method comprises the steps of arbitrarily selecting a plurality of reference points (P) on said original image (31), obtaining density data expressing respective density levels of said reference points (P), correcting said density data according to a predetermined image correction rule, to obtain corrected image data expressing respective corrected density levels of said reference points (P), visually indicating said respective corrected density levels on visual means (64) simultaneously, and adjusting said image correction rule to a desired correction rule while monitoring said respective corrected density levels indicated on said visual means (64), thereby setting-up said image processor.
Claim 11
Dependent Claim
47 words
A method in accordance with claim 8, wherein the method further includes the steps of displaying said original image (31) on said image display (64) and serially designating said reference points (P) on said original image (31) displayed on said image display (64) with a cursor (C).
Claim 12
Dependent Claim
28 words
A method in accordance with claim 8 or 9, wherein the method further includes the step of displaying said corrected density levels together with said original image (31).
Claim 13
Independent Claim
27 words
A method in accordance with any one of claims 8 - 10, wherein said corrected density levels are displayed at respective neighbourhoods of said reference points (P).
Claim 14
Independent Claim
32 words
A method in accordance with any one of claims 8 - 11, wherein the method further includes the step of indicating said corrected density levels with a plurality of respective density indicators.
Claim 15
Independent Claim
84 words
An apparatus provided in a colour process scanner, for indicating respective colour density levels of reference points arbitrarily selected on an original image (31), characterised in that said apparatus comprises a plurality of density indicator units (74) each having a plurality of density indicators for indicating respective colour density levels for each colour and means for receiving colour density data expressing said respective colour density levels from the exterior of said apparatus, to input said colour density data to respective density indicator units (74).
Claim 16
Independent Claim
84 words
An apparatus provided in a colour process scanner, for indicating respective colour density levels of reference points arbitrarily selected on an original image (31), characterised in that said apparatus comprises a plurality of density indicator units (74) each having a plurality of density indicators for indicating respective colour density levels for each colour and means for receiving colour density data expressing said respective colour density levels from the exterior of said apparatus, to input said colour density data to respective density indicator units (74).
