Image processing apparatus, image processing method, program, and electronic device

摘要

An image processing apparatus detects one or more subjects set as detection targets from a shot image acquired by imaging. An image pyramid generator generates an image pyramid used to detect the one or more subjects, wherein the image pyramid is generated by reducing or enlarging the shot image using scales set in advance according to the distance from the imaging unit that conducts the imaging to the one or more subjects to be detected. A detection region determining unit determines, from among the entire image regions in the image pyramid, one or more detection regions for detecting the one or more subjects. A subject detector detects the one or more subjects from the one or more detection regions.
