Patent ID: 8830343

Claim:
A digital camera comprising: an imaging device that photographs a subject; a focusing device that implements a focus action for the subject by using image data output from the image device; a mode setting device that sets an extraction mode so as to extract a predetermined feature portion within the image data output from the imaging device; an extraction device that extracts the predetermined feature portion within the image data output from the imaging device when the extraction mode is set by the mode setting device: a judging device that judges whether or not brightness of the subject is low; a first controller that controls the extraction device in accordance with the brightness of the subject judged by the judging device; and a second controller that controls the focusing device so as to determine a position of focusing area based upon the feature portion extracted by the extraction device and to implement the focus action; wherein: the judging device judges the brightness of the subject is low at least when a rate of the image data output from the imaging device is lower than a normal output rate, and the first controller controls the extraction device so as to halt the extraction of the feature portion when the judging device judges that the brightness of the subject is low, and controls the extraction device so as to extract the feature portion when the judging device judges that the brightness of the subject is not low and the extraction mode is set.
