Abstract
In an ophthalmic imaging apparatus of some aspect examples, a data acquiring unit acquires data by applying an OCT scan to an eye. An image constructing unit constructs an image from the data acquired. A focal position changing unit is provided to the measurement arm. A scan controller controls the data acquiring unit according to a scan pattern including first and second partial patterns that are continuous patterns for central and peripheral regions of an OCT scan application area, respectively. A focus controller controls the focal position changing unit such that a first focal position is applied in parallel with an OCT scan of at least part of the first partial pattern and a second focal position is applied in parallel with an OCT scan to at least part of the second partial pattern.
