Abstract
A camera system includes an image sensor and a processing apparatus receiving image frames from the sensor before and after receipt of a user picture signal. The processing apparatus discards frames that do not meet a quality criterion such as under-exposed frames. Also, the processing apparatus compresses only a subset of remaining frames, specifically, those that meet a compression amount threshold. The remaining frames are presented to a user, who can select a representative frame as the “picture” that was taken.
