1. An image pickup device comprising:
- an image pickup unit configured to convert an optical image of a subject to image data and to output the image data;
a face image recognition unit configured to recognize a face image from the image data; and
a face portion judgment unit configured to judge each portion in the face image recognized by the face image recognition unit, wherein when every portion in the face image can be judged by the face portion judgment unit, a photographing operation for executing photographing of the subject is automatically executed, the face portion judgment unit includingan edge detection unit configured to detect an edge for each portion in the face image, and to acquire edge detection values for respective portions in the face image; and
a determining unit configured to acquire the edge detection values from the edge detection unit, and to determine whether the edge detection values corresponding to respective portions in the face image exceed thresholds for said respective portions respectively,the face portion judgment unit judges that each portion in the face image is identified when the determining unit determines that the edge detection values corresponding to respective portions in the face image exceed the thresholds for said respective portions respectively, andthe edge detection unit continues to acquire the edge detection values until the edge detection values exceed the thresholds, when the determining unit determines that the edge detection values corresponding to respective portions in the face image do not exceed the thresholds for said respective portions respectively.

Abstract
An image pickup device includes an image pickup unit configured to convert an optical image of a subject to image data and to output the image data, a face image recognition unit configured to recognize face image from the image data, and a face portion judgment unit configured to judge each portion in the face image recognized by the face image recognition unit. When every portion in the face image can be judged by the face portion judgment unit, a release button for executing photographing of the subject is automatically pressed, or the photographing operation is executed.
