1. An electronic camera, comprising: an imager which repeatedly outputs a scene image generated on an imaging surface capturing a scene; a searcher which repeatedly executes a process of searching for a specific object image from the scene image outputted from said imager by using a plurality of reference-use specific object images each of which has a posture different from others; a detector which detects the number of specific objects existing in the object scene based on a searched result of said searcher; a determiner which repeatedly determines based on the searched result of said searcher whether or not all of the specific objects equivalent to the number detected by said detector satisfy a posture condition; and a recorder which records the scene image outputted from said imager when a determined result of said determiner is updated from a negative result to a positive result.
