ABSTRACT:
A photographing apparatus and method prevent a resolution of a peripheral portion of an image from being degraded with a simple structure. These employ an in-focus state detector for detecting evaluation values for auto in-focus operation representing an in-focus state of an image from a first in-focus state detection region disposed on a center portion of the image, and at least one second in-focus state detection region disposed on a peripheral portion of the image, a flat subject determiner that determines whether a subject is flat based on the detection result of the evaluation values for auto in-focus operation, a flat subject focusing position calculator that calculates a final focusing position based on the evaluation values when the subject is determined as being flat, and a three-dimensional subject focusing position calculator that calculates a final focusing position based on the evaluation value when the subject is not flat.
