1. A mobile computing device, comprising: a single body camera, containing a first lens with a first image sensor with a first active sensor area and a second lens with a second image sensor with a second active sensor area; a memory containing a first camera setting, including a determination of a portion of the first active sensor area and a portion of the second active sensor area to be actively used to create a registered image, wherein the portions are not the whole first active sensor area and the whole second active sensor area and the determination includes the portions in coordinates of pixels and edges of the first and second active sensor areas to automatically generate the registered image, wherein both the portion of the first active sensor area and the portion of the second active sensor area determined during a first calibration step and all image data of a single image frame generated through the first lens by the portion of the first active sensor area of the first image sensor from a scene merged with all image data of a single image frame generated through the second lens by the portion of the second active sensor area of the second image sensor from the scene form a registered calibration image of the scene; a controller, configured to retrieve during an operational step of the single body camera the first camera setting from the memory; a multiplexer configured to multiplex all the image data of the single image frame generated through the first lens by the portion of the first active sensor area of the first image sensor and all the image data of the single image frame generated through the second lens by the portion of the second active sensor area of the second image sensor; a processor, configured to store on an image memory based on the first camera setting during the operational step the multiplexed image data generated by the portion of the first active sensor area of the first image sensor and image data generated by the portion of the second active sensor area of the second image sensor as contiguous image data representing the registered image; and a display enabled to display the registered image generated from the contiguous image data.
