摘要:
Provided is a fundus image acquiring apparatus in which eyeball tracking can be performed by template matching even if sufficient luminance of a characteristic image of blood vessels or the like is not secured in a case where eye movement is detected accurately from a fundus image. The fundus image acquiring apparatus includes a fundus imaging unit for obtaining a fundus image, an extraction unit for extracting a characteristic image from an initial fundus image taken by the fundus image acquiring apparatus, an evaluation unit for evaluating luminance information of a characteristic point obtained through the extraction, and a setting unit for setting a frame rate for imaging by the fundus image acquiring apparatus. The frame rate is determined based on a result of the evaluation by the evaluation unit.
