Definitions

  • the digital camera 36 may allow for the optics of a film camera to be applied to a digital image sensor 38.
  • the optics of the digital camera 36 may capture an image having a size of approximately 48.62 mm by 22.1 mm, as with 65 mm film, yet at a 4 k digital resolution .
  • the squeeze ratio of the anamorphic lens group 16 may be 2, for example in an embodiment in which the standard 2.4: 1 Panavision widescreen aspect ratio is desired (for a captured 1.2:1 aspect ratio) .
  • the squeeze ratio of the anamorphic lens group 16 may be set to approximately 1.34, for example in an embodiment in which a captured 1.78 aspect ratio is desired, in a manner described in Miyagishima et al. , Anamorphic Three- Perforation Imaging System, U.S. Patent No. 7,148,947, issued December 12, 2006, the entire contents of which are incorporated herein by reference.
  • the squeeze ratio of the anamorphic lens group 16 may be varied as desired .
  • the squeeze ratio of the anamorphic lens group 16a may be varied by about 3% of 1.25, or 1.255, to provide an anamorphic lens group 16b having a squeeze ratio of approximately 1.29.
  • the 3% adjustment may be achieved by introducing or enhancing the size ot an air gap between the front element of the anamorphic lens group 16b and the astigmatizers .
