Technology brief

New Folsom Athena

Scaler

Athena

is a proprietary, high performance image processing

technology designed and developed by Folsom Research. The

scaler has been designed from the ground up to provide the

highest possible image quality while minimizing processing

dela

ys. The architecture supports 1:1 video sampling and

processes video at 10-bits per color channel to maintain image

fidelity. Proprietary horizontal and vertical filtering techniques

e used to provide crisp, clean images to support both upcon-

version and downconversion operations. The Athena

scaler

also supports special functions such as continuous real-time

pan and z

oom operations, a wide variety of frame locking

options (to eliminate motion artifacts) and adjustable filtering

modes.

Motion Adaptive De-Interlacing

Folsom's Motion Adaptive De-Interlacing technology optimizes

image quality when interlaced images (such as standard NTSC

and PAL images) are processed. Image content is analyzed

over multiple input fields and filter coefficients are dynamically

changed to provide crisp, clean output images without de-

interlacing artifacts.

3:2 and 2:2 Pull-down Detection

ImagePRO automatically detects whether NTSC or PAL input

source material is derived from film or standard video compo-

nents such as cameras. When film-based source material is

detected, a 3:2 pull-down algorithm is activated for NTSC inputs.

Similarly, a 2:2 pull-down algorithm is activated if film-based

material is input in PAL format. The 3:2 and 2:2 pull-down

algorithms insure that frame integrity is maintained during

intermediate image processing stages to prevent artifacts and

preserve image detail and sharpness.

Aspect Ratio Conversion and Control

Wide

-screen formats are becoming increasingly popular. It is

often necessary to convert video between formats with diffe-

rent inherent aspect ratios. For example, wide-screen material

sho

t in 16:9 format is often converted for display on a standard

television screen with a 4:3 aspect ratio. ImagePRO supports

conversion between image formats in all common aspect

atios. In addition, user control of custom aspect ratios is pro-

vided.

an and Zoom

ImagePRO supports flexible pan and zoom operations. The Pan

and Zoom controls can be used to see very fine detail in an

area of interest of the input image or to compress an input

image to form a very small output window.

Genlock/Vertical Lock

True blackburst genlock capability with SCH-phase adjustment

is provided for the broadcast quality NTSC and PAL output. All

output formats including HDTV, may be vertically locked to the

blackburst signal.

HV Lock capability is provided to allow the output to be locked

to externally applied high resolution sync signals.

When a non-broadcast output is selected, the Vertical Lock fea-

ture can be enabled to lock the output frame rate to the input

frame rate or an externally supplied vertical sync. Vertical locking

eliminates frame rate conversion problems that would otherwise

result in motion artifacts or allows multiple units to have their

outputs timed together.

Memory Presets

ImagePRO has 64 independent memory presets. The memories

ave sizing, centering, detail, contrast, and brightness informa-

tion.

Enhanc

ed Digital Processing

10-Bit processing provides improved signal-to-noise ratio and

preserves dynamic range to improve image fidelity. This is

specially apparent in dark regions and areas of smooth,

slightly varying tonal values.
