Abstract:
1. An autofocus system, comprising: a focus-verification image-recapturing processor that sets an ISO sensitivity to a value lower than a predetermined value and increases an exposure value by adjusting at least one of an aperture value and an exposure time to carry out a focus-verification still image-recapturing operation when, under the same focusing conditions, the ISO sensitivity set in an antecedent autofocus operation is higher than said predetermined value; and a focus-verification image display processor that displays a focus-verification still image obtained by said focus-verification image-recapturing operation when said ISO sensitivity set in said antecedent autofocus operation is higher than said predetermined value, and displays a focusing verification image captured in said antecedent autofocus operation for focus verification when said ISO sensitivity during said antecedent autofocus operation is less than said predetermined value.
