[[Image:Lens_side_trim.png|thumb|A side view of the lens assembly. Notice that because of the entry angle, one of the illustrated beams is cut off before reaching the second lens. The final image will be only the remaining half of the original.]]
The above equations can generate images magnified or offset beyond what the camera can resolve, as the camera lens assembly has a radius of 3.75 cm. To compensate for this and prevent resolution of an image larger than the camera can allow, we need to superimpose over our final offset and magnified image the effects of the lens assembly. At any given lens, the image will be at either its maximum or minimum magnification counting from the previous lens. These lenses can be generated by the equation
