Abstract
An image acquisition apparatus that uses optical coherence tomography includes a scanning unit provided within a light path that guides signal light to be incident on an examination object towards the examination object and configured to scan the signal light in a main scanning direction; and a control unit configured to control the scanning unit such that an integration time of an optical interference signal per pixel in at least one predetermined area other than opposite ends, in the main scanning direction, of an image acquisition region scanned by a plurality of main scan lines is increased relative to that of an area other than the predetermined area.
