Abstract
In an optical coherence tomography apparatus that generates a full-color optical coherence tomographic image, an image generation unit includes a correction processing unit that calculates an attenuation related value related to attenuation of signal intensity of the interference light of three R, G, and B colors in a first depth region and corrects the signal intensity of a second depth region deeper than the first depth region according to the attenuation related value to calculate a correction signal for the interference light and generates a full-color optical coherence tomographic image using the correction signals calculated for each of R, G, and B.
