1. A method of disqualifying an acquired image as unsatisfactory for permanent storage based on facial expression, comprising: using a digital image acquisition device including a lens, an image sensor and a processor programmed by processor-readable code embedded within one or more storage media; acquiring one or more reference images of a scene including one or more face regions; detecting at least one of said one or more face regions; identifying within the at least one of said one or more face regions within the one or more reference images one or more groups of pixels corresponding to one or more eye pixel regions; and determining whether one or more expressions of said at least one of said one or more face regions are unsatisfactory, including analyzing the one or more eye pixel regions; and if so, then rejecting the scene for full resolution image capture, and instead capturing a consequent full resolution image at a later time, including delaying the timing of said capturing a consequent image for at least a calculated time for said expression to change.
