Abstract
A face area is detected from an image captured by an image pickup device, pixel values of the image are adjusted based on information concerning the detected face area, a person area is detected from the adjusted image, and the detected face area is integrated with the detected person area. With this configuration, it is possible to accurately detect an object even in a case, for example, where the brightness is varied.
Claims7
An image processing apparatus comprising:
- a memory;
- and
- a processor configured to perform as:
- a face-area detecting unit configured to detect a face area from an image captured by an image pickup unit;
- a moving-body-area detecting unit configured to detect a moving body area on the basis of the captured image and a background area;
- an adjusting unit configured to adjust luminance values of the moving body area on the basis of luminance values of the detected face area without adjusting luminance values of the background area;
- a person-area detecting unit configured to detect a person area from the captured image in which the luminance values of the moving body area have been adjusted;
- and
- a determination unit configured to determine each person area in the captured image by combining the detected person area and a person area estimated from the detected face area and deleting an estimated person area overlapped with the detected person area.
