An image processing method includes: obtaining an image; generating a high frequency image according to a high frequency component based on a plurality of first pixel values of a plurality of first pixels of the image obtained; generating, according to color information based on the plurality of first pixel values of the image obtained, one or more color images corresponding to one or more different colors; generating a composite image by weighted addition of the high frequency image and the one or more color images; and outputting the composite image generated.

Image processing method, image processing device, and recording medium for obtaining a composite image by synthesizing a high-frequency image and one or more color images

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.

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.

Intraoral camera system and image display method

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.
