摘要
It is possible to improve the quality of an image of an eyeground, thereby acquiring an optimal image. An eyeground observation system (3) acquires an eyeground image via a compensation optical section (70) correcting the image of the eyeground obtained by illumination of an eyeground illumination system (2). A wave front correction system (1) measures wave front measurement data including a wave front aberration of the eye to be checked and/or aberration to be corrected, thereby acquiring the optical characteristic of the eye to be checked. An image data formation section (14-2) performs simulation of viewing at the eyeground, thereby calculating the simulation image data or MTF data. A correction amount decision section (14-3) decides a correction amount according to a voltage change template stored in a memory (14-4) and outputs it to a control section (15). Moreover, the correction amount decision section (14-3) uses the simulation result for a plurality of voltage change templates so as to calculate a value indicating the matching degree of the pattern or MTF data corresponding to a spatial frequency of cells of the eyeground and decide an appropriate correction amount.
