| Claim: | 1. A dental treatment appliance comprising: a handle; an optical system comprising illuminating means for illuminating an oral cavity of a user, and a window for receiving light from the illuminated oral cavity, and from which the received light is conveyed to image capturing means for capturing images of the illuminated oral cavity; a dental treatment system for delivering a treatment to the oral cavity in dependence on one or more features contained in the captured images; and moving means for moving the illuminating means and the window relative to the handle; wherein the moving means is configured to move the illuminating means and the window relative to the handle at a first frequency F1, and the illuminating means is configured to illuminate the oral cavity at a second frequency F2 to generate a plurality of illumination events each second. |
| Claim: | 2. The appliance according to claim 1 , wherein the illuminating means comprises a plurality of LEDs. |
| Claim: | 3. The appliance according to claim 1 , wherein the window is located adjacent to the illuminating means. |
| Claim: | 4. The appliance according to claim 1 , comprising a head, and a stem extending between the head and the handle, and wherein the moving means is arranged to move the stem and the head relative to the handle. |
| Claim: | 5. The appliance according to claim 4 , wherein the illuminating means and the window are located on the head of the appliance. |
| Claim: | 6. The appliance according to claim 4 , wherein the head of the appliance comprises a plurality of bristles. |
| Claim: | 7. The appliance according to claim 1 , wherein the dental treatment system comprises a nozzle for ejecting working fluid towards the oral cavity. |
| Claim: | 8. The appliance according to claim 7 , comprising a head, and a stem extending between the head and the handle, and wherein the nozzle is located on the head of the appliance. |
| Claim: | 9. The appliance according to claim 1 , wherein the image capturing means comprises a rolling shutter camera. |
| Claim: | 10. The appliance according to claim 9 , wherein the camera comprises a sensor comprising a plurality of rows of pixels, the rows of pixels being exposed sequentially, and wherein each row of pixels is exposed to the same number of illumination events. |
| Claim: | 11. The appliance according to claim 1 , wherein F1=F2. |
| Claim: | 12. The appliance according to claim 1 , wherein the second frequency F2 is selected such that 0<|F1−nF2| |
| Claim: | 13. The appliance according to claim 1 , comprising a sensor for measuring the ambient light intensity, and a controller arranged to vary at least one of the intensity and the duration of each illumination event depending on the measured ambient light intensity. |
| Claim: | 14. The appliance according to claim 1 , wherein the moving means is arranged to move the illuminating means and the window relative to the handle along a path which is arranged perpendicular to a longitudinal axis of the handle. |
| Claim: | 15. The appliance according to claim 14 , wherein the moving means is arranged to move the illuminating means and the window relative to the handle reciprocally along a curved, or arcuate, path. |
