Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
108 words
An image processing apparatus comprising: a) extraction means for extracting an outline of an image represented by input image data; b) process means for coloring the outline extracted by said extraction means with a finite width; and c) identifying means for identifying any isolated points in the image; and d) control means for controlling said process means so that the outline of the image other than any such isolated point in the image is colored, while the outline of any such isolated point is not colored, so that any such isolated point is retained in the image and the outline of any such isolated point is not colored.
Claim 2
Dependent Claim
108 words
An image processing apparatus comprising: a) extraction means for extracting an outline of an image represented by input image data; b) process means for coloring the outline extracted by said extraction means with a finite width; and c) identifying means for identifying any isolated points in the image; and d) control means for controlling said process means so that the outline of the image other than any such isolated point in the image is colored, while the outline of any such isolated point is not colored, so that any such isolated point is retained in the image and the outline of any such isolated point is not colored.
Claim 3
Dependent Claim
22 words
An apparatus according to claim 1, wherein said extraction means is adapted to extract the contour by binarizing the input image data.
Claim 4
Dependent Claim
25 words
An apparatus according to claim 2, wherein said extraction means is adapted to extract the contour by a block process utilizing binarized input image data.
Claim 5
Dependent Claim
23 words
An apparatus according to claim 1, wherein said process means comprises designation means for designating a color to be given to the contour.
Claim 6
Dependent Claim
50 words
An apparatus according to claim 1, wherein said control means is adapted to disable contour extraction of an isolated point in the input image data by said extraction means, by means of a predetermined filter process applied to the input image data, thereby prohibiting the coloring of the isolated point.
Claim 7
Dependent Claim
14 words
An apparatus according to claim 5, wherein said predetermined filter is a median filter.
Claim 8
Dependent Claim
14 words
An apparatus according to claim 5, wherein said predetermined filter is a smoothing filter.
Claim 9
Dependent Claim
127 words
An image processing apparatus comprising: a) extraction means for extracting an outline of an image represented by input image data; b) process means for coloring the outline extracted by said extraction means, the outline being colored with a controllable width; and c) identifying means for identifying any isolated points in the image; and d) control means for controlling said process means so that the outline of the image, other than any such isolated point in the image, is colored while the outline of any such isolated point is not colored, so that any such isolated point is retained in the image and the outline of any such isolated point is not colored wherein said process means comprises means for varying the width of coloring of the outline.
Claim 10
Dependent Claim
127 words
An image processing apparatus comprising: a) extraction means for extracting an outline of an image represented by input image data; b) process means for coloring the outline extracted by said extraction means, the outline being colored with a controllable width; and c) identifying means for identifying any isolated points in the image; and d) control means for controlling said process means so that the outline of the image, other than any such isolated point in the image, is colored while the outline of any such isolated point is not colored, so that any such isolated point is retained in the image and the outline of any such isolated point is not colored wherein said process means comprises means for varying the width of coloring of the outline.
Claim 11
Dependent Claim
105 words
An image processing method comprising the steps of: a) extracting an outline of an image represented by input image data; b) identifying any isolated point in the image; and c) coloring the outline of the image extracted in said extracting step with a finite width, wherein said coloring is performed so that the outline of the image, other than any isolated point in the image identified in said identifying step, is colored, while the outline of any such isolated point is not colored, so that any such isolated point is retained in the image and the outline of any such isolated point is not colored.
Claim 12
Dependent Claim
105 words
An image processing method comprising the steps of: a) extracting an outline of an image represented by input image data; b) identifying any isolated point in the image; and c) coloring the outline of the image extracted in said extracting step with a finite width, wherein said coloring is performed so that the outline of the image, other than any isolated point in the image identified in said identifying step, is colored, while the outline of any such isolated point is not colored, so that any such isolated point is retained in the image and the outline of any such isolated point is not colored.
