Abstract

A fundus imaging apparatus includes an aberration measurement unit adapted to measure an aberration of reflected light obtained by irradiating an object to be examined with measurement light; an aberration correction unit adapted to correct an aberration of light in accordance with the measured aberration; a control unit adapted to repeatedly control processing of the aberration measurement unit and the aberration correction unit; and a changing unit adapted to change a first function of a predetermined order representing the aberration to 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. The aberration correction unit corrects an aberration expressed by the second function.
