Digital photographing apparatus and method for controlling the same based on user-specified depth of focus region

摘要

A digital photographing apparatus allows users to directly reflect their DOF intention to the digital photographing apparatus before a photo is taken, thereby facilitating a more accurate representation of DOF. A method for controlling the digital photographing apparatus includes receiving depth-of-field (DOF) information, calculating an aperture value corresponding to the DOF information, and controlling photographing using the calculated aperture value.

主权项

1. A method for controlling a digital photographing apparatus, the method comprising:
receiving an input of depth-of-field (DOF) information; calculating an aperture value corresponding to the DOF information by:
calculating a high frequency component while increasing an aperture value from a region on which an input image is focused to a region corresponding to the DOF information; anddetermining an aperture value at which the calculated high frequency component begins to decrease as an aperture value corresponding to the DOF information; determining whether the input DOF information is coincident with the calculated aperture value; and controlling a photographing operation using the calculated aperture value, wherein the controlling of the photographing operation is performed using the calculated aperture value when the input DOF information coincides with the calculated aperture value.
