摘要： A single-plate image pickup element picks up an eye fundus image. A tricolor separation color filter includes R, G, and B filter elements arranged in a mosaic so as to correspond to the pixels of the image pickup element. Each virtual pixel value of color image data is calculated from light detection data of adjacent pixels. Thus, image data of a color still image is generated. The R filter elements transmit near-infrared light. Each virtual pixel value is calculated from light detection data of pixels corresponding to B or G filter elements that are adjacent to the R filters and have sensitivity to near-infrared light. Thus, image data of a near-infrared light monochrome moving image is generated.

摘要： In an ophthalmologic apparatus, the coordinates of three illuminated spots on a cornea-reflected image calculated from a front eye part image picked up by a two-dimension image pickup element and a pupil diameter are calculated, and the position of the centroid of the pupil is calculated from the front eye part image. When the pupil diameter is smaller than a predetermined value, alignment is effected from the shift from the center of the pupil, and when the pupil diameter is larger than the predetermined value, alignment is effected on the basis of the shift amounts from the illuminated spots on the cornea-reflected image. Also, a controlling method is changed over by the difference between the positions of the illuminated spots on the cornea-reflected image and the position of the centroid of the pupil. Also, the tolerance level of alignment is varied by the size of the pupil diameter.
