Method and apparatus for obtaining panoramic images |
摘要 |
The present invention provides an apparatus and a method for obtaining panoramic images in which cervical effect is corrected in such a manner that the uniform contrast is shown. According to the apparatus and the method, the method comprises the steps of: obtaining a preceding frame image by irradiating radiation on one certain section of an image layer trace on which the tooth trace of a subject is embodied; calculating a gray scale average value of pixels that are included within a predetermined reference region of the preceding frame image; comparing the calculated gray scale average value with a gray scale reference value that is calculated from a prepared sample image, and generating a radiation correction value corresponding to a difference value therebetween; and obtaining a succeeding frame image by irradiating strength-adjusted radiation on one section that is adjacent to the other section of an unknown layer trace, according to the calculated radiation correction value. |
