Abstract
A method for removing external light interference according to the present disclosure includes: performing the scan in the state where external light is turned on, performing the scan in the state where the external light and internal light are turned on together, and calculating a brightness value from an obtained image. Further, by subtracting the brightness value obtained in the brightness calculating step from a color value of the image through an operation, it is possible to obtain an image and a three-dimensional scan model with the influence of the external light being minimized.
