<p>The invention relates to a method for obtaining panoramic images, comprising:
a) obtaining a preceding frame image by irradiating radiation on any one section of an image layer trace in which a teeth trace of a subject is to be shaped;
b) calculating a gray scale average value of pixels included in a predetermined reference area of the preceding frame image;
c) comparing the calculated gray scale average value with a gray scale reference value calculated from a previously provided sample image, and generating a radiation correction value corresponding to a difference value; and
d) obtaining a succeeding frame image by irradiating intensity-adjusted radiation on another section adjacent to the one section of the image layer trace according to the calculated radiation correction value.</p> |
