1. A camera, comprising: a first and a second imaging unit, each imaging unit including a lens and an image sensor; a portable body; the image sensors of the first and second imaging unit being rotationally aligned in the portable body with a misalignment angle that is determined during a calibration and that is not greater than a pre-determined value; a memory to store setting data generated during the calibration that define first coordinates of a first active area of the image sensor of the first imaging unit that is smaller than a total active sensor area of the image sensor of the first imaging unit and second coordinates of a first active area of the image sensor of the second imaging unit that is smaller than a total active sensor area of the image sensor of the second imaging unit, wherein a combination of the first and second coordinates defines a registered panoramic image; a controller to apply the setting data to process image data from the image sensors of the first and second imaging unit only generated by its first active areas to generate the registered panoramic image; and a memory to store the registered panoramic image in a raw image data format prior to a demosaicing.
