Abstract: An oral-area positioning device is provided in the invention. The oral-area positioning device includes a storage device, a positioning circuit and a calculation circuit. The storage device stores information corresponding to a plurality of oral areas. The positioning circuit obtains a target image from an oral-image extracting device, and obtains a first position estimation result according to the information corresponding to the plurality of oral areas and a first algorithm. The positioning device obtains a second position estimation result at least according to the information corresponding to the plurality of oral areas, a second algorithm and a reference image position of a reference image, wherein the reference image position is one of the oral areas. The calculation circuit generates a third position estimation result according to the first position estimation result and the second position estimation result.

Abstract: A method for distinguishing plaque and calculus is provided. The method is used in a device and includes the following steps: emitting, by a blue light-emitting diode, blue light to illuminate teeth in an oral cavity, wherein the blue light is used to generate autofluorescence of plaque and calculus on the teeth; sensing, by an image sensor, the autofluorescence of plaque and calculus; and distinguishing, by a processor, a plaque area and a calculus area on the teeth based on the autofluorescence.

Abstract: An image processing method for a fluorescence reaction region of teeth. The image processing method includes emitting blue light from a light source to illuminate the teeth in a mouth, so that the teeth generate fluorescence; capturing a first teeth image of the teeth by an image capturing unit; separating the first teeth image into a first red-value image, a first green-value image, and a first blue-value image by a processing unit; transforming the first red-value image into a second red-value image by the processing unit using a pixel value transforming function; and combining the second red-value image, the first green-value image, and the first blue-value image into a second teeth image by the processing unit.

Abstract: An image transmission system is provided. The image transmission system includes a transmitting device and a receiving device which are mutually connected via a number of communication links. The transmitting device receives an original image data, and obtains a region of interest (ROI) image data from the original image data in response to an ROI information. The transmitting device further provides two independent process channels respectively processing the original image data and the ROI image data, and respectively outputting the processed original image data and the processed ROI image data via the communication links. The receiving device receives and combines the processed original image data and the ROI image data to obtain a recovered frame image data.
