Abstract
A camera which performs high precision motion compensation while multiple, serial photographs are taken, by stabilizing the output signal of a motion sensor until the final photograph is taken. An exposure control mechanism causes the camera to take a first photograph after a first time period elapses from the initiation of exposure, and to take a second photograph after a second time period elapses from the first photograph being taken. A motion detector continuously detects motion affecting the camera prior to the first photograph being taken until after the second photograph is taken, and produces a corresponding output signal. A reference level mechanism determines a reference level from the output signal of the motion detector. The reference level is a level of the output signal which indicates that approximately no motion is affecting the camera. The reference level mechanism updates the reference level prior to the first photograph being taken until after the second photograph is taken, to produce a current reference level. In addition, a motion compensation mechanism receives the current reference level from the reference level mechanism and the output signal of the motion detector, and accordingly compensates for motion affecting the camera.
