DENTAL COLORIMETRY APPARATUS
First Claim
1. A dental colorimetry apparatus comprising:
- a first storage section storing images of teeth in association with information about the positions of the teeth in row of teeth;
a contour-line extracting section for extracting contour lines of the teeth from the images of the teeth;
a rectangle-setting section for setting rectangles in the images of the teeth so as to include the contour lines extracted by the contour-line extracting section and so as to circumscribe at least both sides of the teeth; and
an image-generating section for generating a row-of-teeth image by arranging the images of the teeth based on the information about the positions of the teeth in the row of teeth so that the rectangles adjoin each other.

Abstract
A dental colorimetry apparatus that allows the color balance of an entire row of teeth to be checked is provided. The invention provides a dental colorimetry apparatus 2 including a multiband-image storing section 21 storing images of teeth in association with information about the positions of the teeth in row of teeth; a contour-line extracting section 25 for extracting contour lines of the teeth from the images of the teeth; a rectangle-setting section 27 for setting rectangles in the images of the teeth so as to include the contour lines extracted by the contour-line extracting section 25 and so as to circumscribe at least both sides of the teeth; and an image-generating section 29 for generating a row-of-teeth image by arranging the images of the teeth based on the information about the positions of the teeth in the row of teeth so that the rectangles adjoin each other.

11. A dental colorimetry apparatus comprising:
-
a first storage section storing tooth images containing target teeth and partial adjacent teeth adjacent to the target teeth in association with information about the positions of the target teeth in row of teeth; a contour-line extracting section for extracting contour lines of the target teeth and the adjacent teeth from the tooth images; a rectangle-setting section for setting rectangles in the tooth images so as to include the contour lines of the target teeth extracted by the contour-line extracting section and so as to circumscribe at least both sides of the target teeth; and an image-generating section for generating a row-of-teeth image by arranging portions of the tooth images inside the rectangles based on the information about the positions of the target teeth in the row of teeth so that the rectangles inscribe the contour lines of the adjacent teeth in the adjacent tooth images. - View Dependent Claims (12, 13)
