Method, Program and Apparatus for Detecting Object, Computer Readable Recording Medium Storing Object Detection Program, and Printing Apparatus

摘要

An object detection method for detecting a predetermined object image from a target image. A target image is contracted to generate a contracted image, and partitioned to generate a partitioned image. The predetermined object image is detected from the image using the image and a detection frame. The detection frame and the contracted image are used to detect the predetermined object image if the detection frame is equal to or larger than a predetermined size, and the detection frame and the partitioned image are used to detect the predetermined object image if the detection frame is smaller than the predetermined size.
