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.

摘要： A conventional method in which an amount of movement of an eye ball between acquired images is calculated by extracting characteristic images of the fundus and comparing the images is excellent in precision, reproducibility and stability, but requires time for image processing. The aforementioned problem can be solved by using a tracking apparatus including: a fundus imaging apparatus for acquiring a fundus image; and a measurement unit that extracts a characteristic image of a fundus image from a first fundus image captured by the fundus imaging apparatus, detects the characteristic image from a second fundus image that is different from the fundus image, and measures a position change in the fundus images from coordinates of the extracted characteristic image and the detected characteristic image in the respective fundus images, wherein a region in which the characteristic image is detected from the second fundus image is determined so that a region searched for the characteristic image from the first image includes the extracted characteristic image and is broader than a range of movement of the characteristic image resulting from movements of the eye ball within measurement time.
