Abstract
The present invention is designed such that during flash photographing which involves pre-light emission for preventing red eye, focus adjustment is effected on the basis of focus adjustment information detected during the time from after the pre-light emission is effected until shutter release is effected and therefore, the time lag from the detection of the focus adjustment information until the shutter release can be minimized and a photo-taking lens can be reliably focused to a desired object even during flash photographing which involves the pre-light emission.
