Dental apparatus, image acquisition method, and information processing apparatus

1. A dental apparatus, comprising:

a light irradiation unit for emitting a near-infrared light to irradiate an oral cavity;

an image capturing unit for image-capturing the oral cavity light irradiated by the light irradiation unit; and

an output unit programmed to output data for highlighting and displaying that discerns between a plaque site and a calculus site on an image of the oral cavity based on a reflected light amount from an image captured result by the image capturing unit.

2. The dental apparatus according to claim 1 , wherein

the light irradiation unit further emits p-polarized light, and

at least a portion of the data for highlighting and displaying the calculus site on the image of the oral cavity is based on an s-polarized light amount of a returned light from the oral cavity.

3. The dental apparatus according to claim 1 , wherein

the light irradiation unit further emits s-polarized light, and

at least a portion of the data for highlighting and displaying the calculus site on the image of the oral cavity is based on a p-polarized light amount of a returned light from the oral cavity.

4. The dental apparatus according to claim 1 , wherein

at least a portion of the data for highlighting and displaying the calculus site on the image of the oral cavity is based on a scattering degree of a returned light from the oral cavity.

5. The dental apparatus according to claim 1 , wherein

the light irradiation unit further emits a blue light, and

at least a portion of the data for highlighting and displaying the plaque site on the image of the oral cavity is based on a light amount from the oral cavity emitted from the blue light.

6. The dental apparatus according to claim 1 , wherein

a plaque staining agent is administered to the oral cavity, and

at least a portion of the data for highlighting and displaying the plaque site on the image of the oral cavity is based on a color density stained by the plaque staining agent.

7. The dental apparatus according to claim 1 , wherein the output unit outputs the data for visualizing a status change of at least one of the plaque site and the calculus site in the oral cavity.

8. The dental apparatus according to claim 1 , wherein

the output unit outputs the data for being audible of a status change of at least one of the plaque site and the calculus site in the oral cavity.

9. A dental apparatus, comprising:

an insertion unit that is inserted into an oral cavity;

a gripper unit that is connected to the insertion unit;

a light irradiation unit, disposed on the insertion unit, for emitting a near-infrared light for irradiating the oral cavity; and

an image capturing unit, disposed on the insertion unit, that acquires an image captured result of the oral cavity and generates data for highlighting and displaying that discerns between a plaque site and a calculus site on an image of the oral cavity based on a reflected light amount from the image captured result.

10. The dental apparatus according to claim 9 , further including a cleaning unit for cleaning the oral cavity.

11. An image processing unit, comprising:

a receiving unit for receiving an image captured result of an oral cavity;

a control unit that generates an image for highlighting and displaying that discerns between a plaque site and a calculus site on an image of the oral cavity based on a reflected light amount from the image captured result; and

a display unit for displaying the image generated.

12. A method of acquiring an image, comprising:

irradiating an oral cavity with a near-infrared light;

image-capturing the oral cavity light irradiated; and

generating data for highlighting and displaying that discerns between a plaque site and a calculus site on an image of the oral cavity based on a reflected light amount from an image captured result.
