Abstract:
1. A fundus imaging method for a fundus imaging apparatus including (a) an aberration measurement unit configured to measure an aberration of reflected light obtained by irradiating an object to be examined with measurement light, (b) an aberration correction unit configured to correct the aberration of light in accordance with the measured aberration, and (c) a control unit configured to repeatedly control processing of the aberration measurement unit and the aberration correction unit, the method comprising: a selecting step of selecting between a first function including a predetermined order representing the aberration and a second function including an order higher than the predetermined order in accordance with at least one of a measurement result obtained by the aberration measurement unit and a control result obtained by the control unit, wherein the first function includes coefficients of Nth-order to Mth-order representing the aberration (N and M are natural numbers satisfying a relation of M>N), and the second function includes coefficients of Nth-order to Lth-order representing the aberration (L is a natural number satisfying a relation of M<L, M≠L); and an aberration correction step of correcting an aberration expressed by the first function or the second function based on a result of the selecting step.
