An examination apparatus detecting first reflected light from a first eye of a subject and second reflected light from a second eye of the subject includes an imaging device, and a processing unit. The imaging device includes pixels each including a first photoelectric conversion unit and a second photoelectric conversion unit. The processing unit includes a unit configured to acquire a first signal based on the first reflected light entering the first photoelectric conversion units and a second signal based on the second reflected light entering the second photoelectric conversion units, a unit configured to acquire crosstalk amounts of the first and second signals based on information about positions of the first and second eyes, and a unit configured to generate correction signals based on the first and second signals and amounts of the crosstalk.
