Abstract
A machine vision system and associated triggering method utilizes images acquired by a video camera to trigger the video camera to acquire an image feature of interest. The video camera continuously acquires images of an object using a portion of the total field of view of the video camera. The acquired images are compared to a signature image. In response to determining that one or more of the acquired images matches the signature, the video camera is triggered to acquire a full-frame image which contains the feature of interest.
