Patent ID: 7113616

Claim:
An object detecting method for detecting an object in comparison between an input image from an image pick-up device having a zoom mechanism and a template image stored in memory, said object detecting method comprising the step of: storing a first image within a view field of said image pick-up device as said template image; recording a power of said zoom mechanism to be changed; pick-up a second image to be detected from said image pick-up device; changing a size of either one of said template image and said second image on the bases of said changed power of said zoom mechanism; and performing a template between said template image and said second image to detect said object, wherein the step of recording a power of said zoom mechanism to be changed comprises the steps of: storing a first focal distance of said zoom mechanism at a time when said template image is picked-up, and detecting a second focal distance of said zoom mechanism at a time when a second image from said image pick-up device is picked-up.
