Abstract: An intraoral camera system includes an imaging unit and an image determination unit. The imaging unit generates an image data item showing a target tooth for image capturing inside a mouth. The image determination unit defines two-dimensional plane coordinates for the image data item generated by the imaging unit and extracts the position coordinates of the outline of the target tooth from the entire imaging area of the imaging unit. When a part of the outline of the target tooth is outside an effective area set inside the entire imaging area of the imaging unit, the image determination unit determines that the target tooth extends beyond the effective area.

Abstract: An intraoral camera system includes an imaging unit and an image processor. If a first angle formed by an imaging plane perpendicular to the optical axis of the imaging unit and a first direction that is the vertically upward direction along a vertical axis is less than a predetermined second angle, the image processor rotates image data to cause the vertically upward direction along the vertical axis to coincide with an upward direction of an image by rotating the image data by a third angle formed by the first direction and a second direction from a handle toward a head.

Abstract: An intraoral camera system includes an imaging unit that generates image data by capturing an image of a tooth inside the mouth of a user, an area detector that detects the orientation of the imaging unit according to output by a multi-axis acceleration sensor and detects, according to the orientation detected, an area whose image is being captured by the imaging unit from among areas inside the mouth, the areas being determined by dividing a dentition into sections, and an identifier that narrows candidates which are combinations of tooth types and tooth positions down to fewer candidates to be used, according to the image data and the area detected, and identifies the type and the position of the tooth according to the narrowed candidates and the image data.
