1. An imaging apparatus, comprising: circuitry configured to capture an image of a subject, determine whether or not to enable a user to check an effect of an aperture of a captured image for storage in a through-the-lens image, based on a determination of whether the subject is under a flicker condition, control exposure of the through-the-lens image between exposure appropriate for the through-the-lens image and exposure for the captured image for storage, which is different than the exposure appropriate for the through-the-lens image, when a determination is made to enable the user to check the effect of the aperture of the captured image for storage in the through-the-lens image, and control exposure of the through-the-lens image to the exposure appropriate for the through-the-lens image when a determination is made to not enable the user to check the effect of the aperture of the captured image for storage in the through-the-lens image.
