Photographing apparatus, photographing method and a computer readable medium of instructions for controlling the photographing apparatus

A photographing method comprising:

• detecting evaluation values for auto in-focus operation, which represent in-focus states, from a first in-focus detection region on a center portion of a photographing image and at least one second in-focus detection region on a peripheral portion of the photographing image;
• determining whether a subject to be photographed is a flat subject based on the result of detecting the evaluation values for auto in-focus operation from the first and second in-focus detection regions;
• calculating a final focusing position based on the evaluation values for auto in-focus operation from the first and second in-focus detection regions if the subject is determined as a flat subject;
• and
• calculating a final focusing position based on the evaluation value for the auto in-focus operation obtained from the first in-focus detection region if the subject is determined to not be a flat subject.

A computer readable medium of instructions for controlling a photographing apparatus, comprising:

• a first set of instructions for controlling the photographing apparatus to detect evaluation values for auto in-focus operation, which represent in-focus states, from a first in-focus detection region on a center portion of a photographing image and at least one second in-focus detection region on a peripheral portion of the photographing image;
• a second set of instructions for controlling the photographing apparatus to determine whether a subject to be photographed is a flat subject based on the result of detecting the evaluation values for auto in-focus operation from the first and second in-focus detection regions;
• a third set of instructions for controlling the photographing apparatus to calculate a final focusing position based on the evaluation values for auto in-focus operation from the first and second in-focus detection regions if the subject is determined as a flat subject;
• and
• a fourth set of instructions for controlling the photographing apparatus to calculate a final focusing position based on the evaluation value for the auto in-focus operation obtained from the first in-focus detection region if the subject is determined to not be a flat subject.
