True 10-Bit Processing
Geo offers complete input-to-output 4:4:4 color processing. Extended Internal Bit Precision By extending the internal processing of warp map calculations from 12-bit to 16-bit, Geo enables 1/32 pixel accuracy for: More precise convergence and alignment applications More precise correction for curved mirror profiles, allowing for better image quality More precise correction for distortion due to mirror flex or chassis flex More precise factory and field alignment and calibration.
Geometry Processing
Geo's unprecedented geometry processing engine can correct for lens distortion, lens lateral chromatic aberration, geometry distortions, rotational misalignments, brightness and color non-uniformities, 2- and 3-panel convergence, independently for each channel (sxW2-300) at full 1920 x 1080p @60 Hz video rates.
Geometry Correction Engine
The chip allows for: Lateral chromatic aberration correction in projection lenses, lowering cost of the lens and allowing for improving the MTF (Modulation Transfer Function) and f# (ratio of lens focal length to its entrance pupil diameter) Extreme LCA correction in three discrete wavelengths allows effective use of 3-color solidstate laser or LED illumination in all-spherical element lens designs (sxW2-300) Independent misalignment/convergence adjustment for 3x LCD and 3x LCOS RPTVs. More precise and rapid factory alignment/calibration. Field calibration and alignment of light engines (procedure never attempted nor possible in the past) Very aggressive ultra-thin chassis RPTV (Slimline™) designs.
Per-Channel Brightness Compensation
Per-channel brightness/shading non-uniformity compensation allows for: Improvement in image quality of projection-based systems (as they are all subject to brightness nonuniformity, due to vignetting and 4th power cosine losses) Compensation for color shade variations in light engines, due to prism and dichroic coating performance variations with light incidence angles and wavelengths, and stress birefringence. Compensation in brightness due to light leakage in the chassis, both in the factory and in the field
Target Applications
Increase performance, and decrease BOM (Bill of Materials) for the following applications:
- Projection light engine
- 3-sensor camera engine
- Projection engine/camera engine alignment and calibration
- Projection engine/camera engine brightness/color non-uniformity compensation
- Brightness non-uniformity compensation in direct view LCD TVs
- Fixed focal length lenses (sxW2-300)
- Zoom lenses (sxW2-300)
