Abstract:
An ophthalmic imaging apparatus divides a frame image obtained by capturing a moving image into a plurality of regions grouping pixels, and acquires photometric values corresponding the plurality of the regions. Further, the ophthalmic imaging apparatus determines acknowledgement or dis-acknowledgement of capturing a still image based on temporal variation of the acquired photometric values or distribution of the acquired photometric values on a fundus image. The ophthalmic imaging apparatus inhibits to execute a still image capturing of the fundus if the dis-acknowledgement of capturing is determined.
