Abstract:
1. A digital photographing apparatus comprising: a lens; an imaging device that generates data from light incident on the imaging device through the lens; a condition determining unit that determines a photographing condition from the data generated by the imaging device; and an auto-focusing value detecting unit that detects an auto-focusing value from the data generated by the imaging device and that comprises a first gamma correction unit, wherein after the first gamma correction unit varies a degree of gamma correction according to the photographing condition determined by the condition determining unit, the auto-focusing value detecting unit detects an auto-focusing value for the varied degree of gamma correction, wherein if the condition determining unit determines the condition as a back light condition, the first gamma correction unit gamma-corrects the data generated by the imaging device such that luminance of a region of a subject to be auto-focused on is high.
