ABSTRACT:
An orientation sensor for use with an image sensor is provided, which includes at least two polarizers with different orientations and associated photodetectors and a signal processing unit. The orientation sensor can be incorporated in a digital camera. When the camera is exposed to daylight, which is polarized, the relative outputs from the differently oriented polarizers can be compared to record the orientation of the camera. This orientation can be stored with the image data so that a user does not have to manually change the orientation of an image on an image display device.
