Regular Lens

Figure 3: Image formation with the primary lens

The polyoptic wheel's first setting allows the user to take regular perspective photos, of the type taken by any other camera. For this setting, the wheel does not use an optical module, just a hole through which light from the scene passes to the primary lens on the printed circuit board. Figure 3 shows a simplified (single lens) version of Bigshot's primary lens, which has a field of view of 40° in the horizontal direction. The lens projects this field of view (shown using the red rectangle) onto the image sensor. For more details of how lenses work, visit Imaging Lens.
