    摘要: Fundus examination is effected by the steps of irradiating the fundus of an examined eye with a measuring beam through a deflector, irradiating the fundus of the eye with a tracking beam through the deflector to thereby obtain tracking information, and controlling the deflector on the basis of the tracking information and executing tracking, calculating a position at which the reliability of a signal obtained by a light receiving system is relatively improved during the tracking, and controlling the deflector so that the measuring beam may be irradiated to this position; and frequency-analyzing the signal obtained by the light receiving system and calculating the velocity of blood flow. The aforementioned reliability is evaluated by means of the SN ratio and quality value of the signal.

    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.
