Patent ID: 7270415

Claim:
An retina observation apparatus comprising: an retina illumination unit for illuminating the retina of an eye under examination for the purpose of observation; a compensating optical section for correcting a image of the retina formed by the illumination of the retina illumination unit by a given amount of correction; an retina-image-forming optical block for forming an retina image by receiving the image of the retina corrected by the compensating optical section; an retina-image-light-receiving section for receiving the retina image formed by the retina-image-forming optical block; a wavefront measurement block for obtaining wavefront measurement data including at least either or both of a wavefront aberration of the eye under examination and the aberration corrected by the compensating optical section; an optical characteristics measurement block for obtaining optical characteristics including a high-order aberration of the eye under examination, from the wavefront measurement data given by the wavefront measurement block; an image data formation block for simulating the manner in which a visual target is perceived on the retina, in accordance with the optical characteristics obtained by the optical characteristics measurement block, and calculating data indicating the manner of perception; a storage block for storing a plurality of voltage-change templates for use in an adjustment of the compensating optical section; and a correction amount determination block for selecting a voltage-change template stored in the storage block, determining an amount of correction to be made by the compensating optical section in accordance with the template and outputting the amount of correction to the compensating optical section, obtaining evaluation data for evaluating the quality of the image in accordance with the data indicating the manner in which the visual target is perceived, obtained by the image data formation block, in consideration of the amount of correction based on the plurality of voltage-change templates, determining an appropriate amount of correction to be made by the compensating optical section in accordance with the evaluation data, and outputting the appropriate amount of correction to the compensating optical section.
