Abstract
Abstract An apparatus for searching a contour line of an image to be cut out, has a displaying device to display an image obtained when an original image is subjected to photographic conversion scanning, a belt-shaped region setting device to set a belt-shaped region at a designated position located along a contour line of an image to be cut out, and a contour line searcher and processor to process image data in a belt-shaped region that has been set by the belt-shaped region setting device and to search a contour line of the image to be cut out, based on the image data processed by the processor.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
191 words
An apparatus for searching a contour line of an image to be cut out, comprising: displaying means for displaying an image obtained through photoelectric conversion scanning of an original image; belt-shaped region setting means for setting a belt-shaped region by designating at least two points located along the contour line of an image to be cut out; processing means for processing image data in the belt-shaped region that has been set by said belt-shaped region setting means; contour line searching means for searching the contour line of the image to be cut out, based on the image data processed by said processing means; a tracer for extracting a contour point located on the contour line of an image in accordance with an image data in a width direction of the belt-shaped region; and wherein the tracer is moved in a direction perpendicular to the width direction so as to continuously extract each contour point, thereby searching the contour line; and wherein said belt-shaped region setting means is arranged such that a weight distribution for determining a contour point by said tracer is set in the width direction of the belt-shaped region.
Claim 2
Independent Claim
191 words
An apparatus for searching a contour line of an image to be cut out, comprising: displaying means for displaying an image obtained through photoelectric conversion scanning of an original image; belt-shaped region setting means for setting a belt-shaped region by designating at least two points located along the contour line of an image to be cut out; processing means for processing image data in the belt-shaped region that has been set by said belt-shaped region setting means; contour line searching means for searching the contour line of the image to be cut out, based on the image data processed by said processing means; a tracer for extracting a contour point located on the contour line of an image in accordance with an image data in a width direction of the belt-shaped region; and wherein the tracer is moved in a direction perpendicular to the width direction so as to continuously extract each contour point, thereby searching the contour line; and wherein said belt-shaped region setting means is arranged such that a weight distribution for determining a contour point by said tracer is set in the width direction of the belt-shaped region.
Claim 3
Dependent Claim
57 words
The apparatus of claim 1, further comprising mode switching means for automatically switching to a manual cutout contour line setting mode, and wherein when said tracer determines a contour point outside the belt-shaped region, a searching operation of the contour line is stopped, and the mode is automatically switched to the manual cutout contour line setting mode.
Claim 4
Dependent Claim
45 words
The apparatus of claim 1, wherein said contour line searching means is arranged such that when said tracer cannot extract a contour line, the contour line is set by means of an extrapolation along a direction perpendicular to the width direction of the belt-shaped region.
Claim 5
Dependent Claim
36 words
The apparatus of claim 1, wherein said belt-shaped region setting means is arranged such that a configuration of the belt-shaped region can be curved in a direction perpendicular to the width direction of the belt-shaped region.
Claim 6
Independent Claim
139 words
An apparatus for searching a contour line of an image to be cut out, comprising: displaying means for displaying an image obtained through photoelectric conversion scanning of an original image; belt-shaped region setting means for setting a belt-shaped region by designating at least two points located along the contour line of an image to be cut out; processing means for processing image data in the belt-shaped region that has been set by said belt-shaped region setting means; and contour line searching means for searching the contour line of the image to be cut out, based on the image data processed by said processing means; and wherein said belt-shaped region setting means is arranged such that a width of the belt-shaped region is set at a ratio, based on a size of a cutout image displayed by said displaying means.
Claim 7
Independent Claim
139 words
An apparatus for searching a contour line of an image to be cut out, comprising: displaying means for displaying an image obtained through photoelectric conversion scanning of an original image; belt-shaped region setting means for setting a belt-shaped region by designating at least two points located along the contour line of an image to be cut out; processing means for processing image data in the belt-shaped region that has been set by said belt-shaped region setting means; and contour line searching means for searching the contour line of the image to be cut out, based on the image data processed by said processing means; and wherein said belt-shaped region setting means is arranged such that a width of the belt-shaped region is set at a ratio, based on a size of a cutout image displayed by said displaying means.
Claim 8
Dependent Claim
36 words
The apparatus of claim 5, wherein said belt-shaped region setting means is arranged such that a configuration of the belt-shaped region can be curved in a direction perpendicular to the width direction of the belt-shaped region.
Claim 9
Independent Claim
134 words
An apparatus for searching a contour line of an image to be cut out, comprising: displaying means for displaying an image obtained through photoelectric conversion scanning of an original image; belt-shaped region setting means for setting a belt-shaped region by designating at least two points located along the contour line of an image to be cut out; processing means for processing image data in the belt-shaped region that has been set by said belt-shaped region setting means; and contour line searching means for searching the contour line of the image to be cut out, based on the image data processed by said processing means; and wherein said belt-shaped region setting means is arranged such that a configuration of the belt-shaped region coincides with an external locus of a circle moved between two designated points.
Claim 10
Independent Claim
134 words
An apparatus for searching a contour line of an image to be cut out, comprising: displaying means for displaying an image obtained through photoelectric conversion scanning of an original image; belt-shaped region setting means for setting a belt-shaped region by designating at least two points located along the contour line of an image to be cut out; processing means for processing image data in the belt-shaped region that has been set by said belt-shaped region setting means; and contour line searching means for searching the contour line of the image to be cut out, based on the image data processed by said processing means; and wherein said belt-shaped region setting means is arranged such that a configuration of the belt-shaped region coincides with an external locus of a circle moved between two designated points.
Claim 11
Dependent Claim
36 words
The apparatus of claim 7, wherein said belt-shaped region setting means is arranged such that a configuration of the belt-shaped region can be curved in a direction perpendicular to the width direction of the belt-shaped region.
