A camera system 1 with an image pickup unit 16, which uses a facial tracking system 13 to detect an observation direction of a user, which is used to select a small region (125, Fig. 11A) to crop out of a wide-angle image (121, Fig. 11A). The system can also detect and correct the direction and the recorded image for deviation of the camera relative to the user’s body (Figs. 24A, 24B), perhaps based on the position of the user’s throat and chin (9206 and 9207, Fig. 27). In cases of high deviation, the recorded image may be enlarged. The tracking system may also detect head roll (Figs. 30A, 30B) and adjust the captured image (Figs. 33A, 33B), and may filter out jaw movements due to exercising, eating or talking, by filtering the head angle (Fig. 36A) and perhaps a microphone. There may be an alarm to warn the user when the camera deviates too much or too often. There may be a calibrator, (850, Figs. 22B and 41B) where the image from the camera is displayed (4001, Fig. 41B) along with an ...
