An object detection apparatus receives an input of a compressed image stream, extracts, from a block included in the input compressed image stream, predetermined compression encoded information representing a feature of a compressed image, and determines, based on the extracted predetermined compression encoded information, whether or not the block is a candidate block including at least a part of the specific object. The object detection apparatus identifies, in a decoded image decoded from the compressed image stream, a candidate region of a predetermined size including the candidate block, calculates a predetermined feature amount from image data of the candidate region, and determines, based on the calculated predetermined feature amount, whether or not the candidate region includes at least a part of the specific object.
