ABSTRACT:
When focus adjustment operation is performed, a first measured distance acquired by utilization of TTL-AF and a second measured value acquired by utilization of a distance between the eyes have been computed in advance. The degree of reliability of the first measured distance is compared the degree of reliability of the second measured distance in accordance with a result of a determination as to whether or not a face is detected, a result of a determination as to whether or not an ambient brightness value Br is equal to or less than a reference value, a result of a determination as to whether or not a focal length “f” is equal to or less than a reference value, and a result of a determination as to whether or not a second measured distance De is less than a first measured distance Dt.
