ELECTRONIC CAMERA AND IMAGE PROCESSING METHOD

摘要

It is possible to provide an electronic camera and an image processing method which can perform a highly accurate tracking process even when an object is viewed in various ways. The electronic camera includes: a tracking process unit (137), an update region detection circuit (139), an update judgment circuit (140), and a tracking result plot circuit (144). The tracking process unit (137) searches inside of a frame by using a color characteristic amount of an object to be tracked, calculates a first evaluation value indicating the matching degree between an image of a search result and the object, and identifies a target region which is estimated to contain an image of the object according to the first evaluation value. The update region detection circuit (139) searches inside of the frame by using a shape characteristic amount of the object to be tracked, calculates a seconds evaluation value indicating the matching degree between the image of the search result and the object, and identifies an update region for updating the first characteristic amount according to the second evaluation value. The update judgment circuit (140) judges whether to update the first characteristic amount depending on whether the first evaluation value or the second evaluation value satisfies a predetermined condition. If No, the tracking result plot circuit (144) plots an external frame of the target region. If Yes, the tracking result plot circuit (144) plots an external frame of the update region.
