Abstract
The present invention relates to an apparatus having a simple configuration capable of correctly detecting malfunction of an OCT apparatus by detecting the states of a light source and a sensor. An image pickup apparatus includes a switching unit that switches between a first mode in which a combined light beam of a return light beam from a specimen and a reference light beam is detectable by a detecting unit and a second mode in which the reference light beam is detectable by the detecting unit. The image pickup apparatus is switchable to the first mode on the basis of an intensity of the reference light beam detected by the detecting unit in the second mode.
