1. An electronic camera, comprising: an imager having an imaging surface to capture an object scene for repeatedly generating an object scene image; an assigner which assigns a search area on said imaging surface; an electronic searcher which repeatedly executes search processing to search a feature image on the search area assigned by said assigner in parallel with executing generation processing by said imager; an outputter which outputs position information representative of a position of the feature image detected by said searcher; a detector which detects at least one of panning and tilting of said imaging surface; and a changer which changes at least one of a size and a position of the search area assigned by said assigner in response to the detection of the at least one of panning and tilting of said imaging surface.
