Face detection image processing device, camera device, image processing method, and program

A camera device comprising:

• an image pickup element;
• an optical system for forming an image of a subject on said image pickup element;
• and
• an image processing device capable of subjecting an original image picked up with a wide-angle lens by said image pickup element to distortion correction using a distortion correcting parameter, wherein said image processing device includes a face detector configured to detect a face from an image given on a basis of detection information, and
• a processing unit configured to set the detection information of said face detector, receive at least an input image before distortion correction of the image before the distortion correction and an image after the distortion correction, divide an entire image region of the input image, and supply each of the divided images to said face detector on a time-division basis, and
• said face detector detects faces from a face of a maximum size to a face of a minimum size in the entire image in a detectable range.

An image processing method for detecting a face from an image given on a basis of detection information set in a face detector, said image processing method comprising the steps of:

• setting said detection information;
• dividing at least an entire image region before distortion correction of images before the distortion correction and after the distortion correction;
• and
• supplying each of the divided images to said face detector on a time-division basis, wherein said face detector detects faces from a face of a maximum size to a face of a minimum size in the entire image in a detectable range.

A non-transitory computer readable medium having stored thereon computer executable image processing instructions for detecting a face from an image given on a basis of detection information set in a face detector, said image processing instructions comprising:

• setting said detection information;
• dividing at least an entire image region before distortion correction of images before the distortion correction and after the distortion correction;
• and
• supplying each of the divided images to said face detector on a time-division basis,
• wherein said face detector detects faces from a face of a maximum size to a face of a minimum size in the entire image in a detectable range.
