Abstract
A fundus image detection apparatus capable of detecting a fundus image of an eye of an animal is provided. The fundus image detection apparatus includes an image capturing unit and an image processing unit electrically connected with the image capturing unit. The image processing unit has a lookup table. The image processing unit corrects the fundus image of the eye of the animal according to the lookup table to diminish pincushion distortion. Moreover, a method for obtaining a fundus image of an eye of an animal is also provided.
Claims19
