Abstract: A dentition image capturing system includes: illumination devices to radiate light; an imaging device to capture first and second dentition images in a predetermined exposure period; a high luminance region extraction unit to extract a high luminance region for the first and second dentition images; a high luminance region comparison unit to calculate a degree of similarity between the high luminance region of the first dentition image and the second dentition image; a halation region specification unit to specify the high luminance region of the first dentition image as a halation region in a case where the similarity degree is smaller than a predetermined threshold; an image synthesis processing unit executing image synthesis processing of extracting a trimming region in the second dentition image corresponding to the halation region and replacing the halation region with the trimming region; and a dentition image output unit to output the first dentition image.

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 imaging apparatus includes an imager, a receiver, a synchronization signal generator, and a time code controller. The imager performs an imaging operation according to a synchronization signal. The receiver receives a time code signal including time code information and a synchronization pattern for detecting the time code information from another imaging apparatus. The synchronization signal generator generates the synchronization signal so as to be synchronized with a timing of the synchronization pattern included in the time code signal received. The time code controller generates a time code based on the synchronization signal and the time code information received.
