Abstract: A magnifying glass captures an image of a tooth by a plurality of cameras for observation. The plurality of cameras includes a narrow range camera capturing a narrow range image of the tooth and a wide range camera capturing a wide range image of the tooth. The magnifying glass includes a three-dimensional position calculator detecting a three-dimensional position of at least the tooth based on the wide range image; a blur correction processor correcting a blur of the narrow range image, based on a change in a three-dimensional positional relationship between the tooth, the three-dimensional position of which has been detected by the three-dimensional position detector, and the narrow range camera; and an image display portion displaying at least the narrow range image having the blur corrected.

Abstract: An information processing apparatus includes management circuitry that manages three-dimensional data obtained by a scanner in the order of obtaining, display controller circuitry that controls a display to show a three-dimensional image generated from combined data generated by combining a plurality of pieces of three-dimensional data, and input circuitry that accepts an operation by a user. When the input circuitry accepts an operation to select three-dimensional data, the management circuitry sets, from the selected three-dimensional data of last obtained three-dimensional data, data to be deleted. The display controller circuitry controls the display to show a three-dimensional image modified to exclude the data to be deleted.

Abstract: A magnifying glass captures an image of a tooth by a plurality of cameras for observation. The plurality of cameras includes a narrow range camera capturing an image of the tooth in a narrow image capturing range and a wide range camera capturing an image of the tooth in a wide image capturing range. The magnifying glass includes a three-dimensional position calculator detecting a three-dimensional position of at least the tooth based on the wide range image captured by the wide range camera; a blur correction processor correcting a blur of the narrow range image captured by the narrow range camera, based on a change in a three-dimensional positional relationship between the tooth, the three-dimensional position of which has been detected by the three-dimensional position detector, and the narrow range camera; and an image display portion displaying at least the narrow range image having the blur corrected.
