IMAGING DEVICE
A digital signal circuit 18 detects a human body from an image signal obtained by photographing, and detects a face portion. A system control circuit 20 estimates an age of the human body from a proportion of a head portion to a shoulder potion of the human body, determines that the object is an infant if the estimated age is equal to or lower than a threshold age, and automatically flashes an LED 30 to attract the attention of the object.
1 . A imaging device comprising:
an optical system comprising a lens;
an imaging section which converts an object image formed by the optical system to an electrical signal; and
a controlling section which estimates an age of an object based on at least one of a human body detected using an edge pattern of an image signal obtained by the imaging section and a face portion detected from the image signal obtained by the imaging section, determines whether or not the object is an infant from the estimated age, and if the object is determined to be an infant, automatically outputs visual or auditory information to the object.
2 . The imaging device according to claim 1 , wherein
the controlling section estimates the age using a ratio between a length of a head portion and a length of a shoulder portion of the human body.
3 . The imaging device according to one of claims 1 , wherein
the controlling section estimates ages from both the human body and the face portion, and if the estimated ages match within a predetermined acceptable range, determines whether or not the object is an infant using the estimated age.
4 . The imaging device according to claim 1 , wherein
the controlling section changes a form of an output between the visual information and the auditory information according to the accuracy of the estimated age.
5 . The imaging device according to claim 1 , wherein
if the controlling section determines the object to be an infant, the controlling section causes light to blink.
6 . The imaging device according to claim 1 , wherein
if the controlling section determines the object to be an infant, the controlling section outputs sound.
7 . The imaging device according to claim 1 , wherein
if the controlling section determines the object to be an infant, the controlling section displays a video.
