1. A camera, comprising: a portable and mobile body containing a first and a second imaging unit, each imaging unit including a lens and an image sensor, wherein the image sensor of the first imaging unit and the image sensor of the second imaging unit are rotationally misaligned in the camera with a misalignment angle that is determined during a calibration; a controller to apply data generated during the calibration to store image data generated by the image sensor of the first imaging unit and the image sensor of the second imaging unit as a rotationally aligned and registered image on a memory in a raw data format prior to a demosaicing step; and a processor to perform the demosaicing step on the rotationally aligned and registered image in raw data format.
