Abstract

A camera adjusting system includes a first camera, a second camera, and a control apparatus. The first camera is used to monitor a locale. The second camera captures a three dimensional (3D) image of a head of a subject. The control apparatus receives the captured 3D image of the head of the subject and models a corresponding 3D model according to the captured 3D image. Compares the actual 3D model with a reference 3D model, to compute a compared result, and outputs a control signal to the first camera to adjust parameters of the first camera according to the compared result.
