Abstract

A camera device with a sensor which is mounted at an angle relative to a mounting surface or other reference surface is described. Camera modules, which include mirrors for light redirection, which are mounted at different angles in the camera device have sensors with different amounts of rotation. In some embodiments modules without mirrors use camera modules without rotated sensors while camera modules with mirrors may or may not use sensors which are rotated depending on the angle at which the modules are mounted in the camera device. By rotating the sensors of some camera modules rotation that maybe introduced by the angle at which a camera module is mounted can be offset. The images captured by different camera modules are combined in some embodiments without the need for computationally rotating an image thanks to the rotation of the sensor in the camera module used to capture the image.
