5 DCP CS Screen, No Anamorphic Lens WS (1:1,85) 1998 x 1080 pixel changing prime lens settings CS (1:2.39) 2048 x 858 pixel WS: prime lens set to fill the complete high of the screen ( 1080 pixel = max. screen high) CS: prime lens set to fill the complete width of the screen ( 2048 pixel = max. screen width) needs change of prime lens setting between WS and CS: motorized lens holder recommended Screen native DLP resolution 2048 x 1080 (aspect ratio 1,9) 5

6 DCP CS Screen, Fixed Prime Lens pixel & light loss! CS (1:2.39) 2048 x 858 pixel WS (1:1.85) 1587 x 858 pixel Prime lens set to cover the complete width of the screen for CS content Same settings are used for WS WS content must also be projected in a letterbox Screen native DLP resolution 2048 x 1080 (aspect ratio 1,9) 6

7 DCP CS Screen, Fixed Prime Lens CS (1:2.39) projection: WS (1:1.85) projection: projected resolution: 2048 x 858 1,76 mega pixel pixel and light loss of 20% projected resoultion: 1587 x 858 1,36 mega pixel (!!!) pixel and light loss of 38% Keep in mind: home cinema HD 1920 x ,1 mega pixel (!) 7

21 DCP lens configurations WCL Wide conversion lens vs. Motorized lens holder 21

22 WCL - Wide Conversion Lens WS (1:1.85) 1998 x 1080 pixel Lens Converter CS (1:2.39) 2048 x 858 pixel Projected resolution for CS 2048 x 858 1,76 mega pixel Pixel and light loss of 20% Screen native DLP resolution 2048 x 1080 (aspect ratio 1.9) 22

23 DCP Motorized Lens Holder Most prime lenses cover both, WS and CS Lens settings stored in preset files (lens files) automated operation Controlled axis: zoom, shift horizontal, shift vertical, focus* WS (1:1,85) 1998 x 1080 pixel changing prime lens settings CS (1:2.39) 2048 x 858 pixel Lens files can be included in automation * depending on prime lens type User-Interface motorized lens holder DCP 23

24 DCP - WCL Vs. Motorized Lens Holder WCL Doesn t solve the problem of pixel / light loss ( still 20% for scope) Separate, manual focus for the WCL fault sensitive Price: lens 4 k + lens holder 2.5 k total 7.5 k (+ installation) Motorized lens holder No additional lens No additional lens holder New wide range prime lenses cover both, WS and CS Will also work with 3D systems installed in front of the projector Square pixels Completely automated workflow Price: 2 3 k 24
