Abstract: An ophthalmologic apparatus includes: a spectroscopic member that separates light emitted from a light source into a first spectral component and a second spectral component; an optical scanner that guides the first spectral component and the second spectral component to an observation target region of a subject's eye including a plurality of imaging target lines formed by dividing the observation target region in a scanning direction; a line exposure imaging element that includes a plurality of exposure lines capable of detecting return light from the observation target region in the light receiving region; and a controller that illuminates a region of the imaging target lines corresponding to the two or more exposure lines forming the exposure line group with the first spectral component and the second spectral component to perform focus determination based on the result of detection by the exposure lines in the exposure line group.
