Sharpness: Uses variable filtering to affect input picture detail and definition. This control is only
available for composite, S-Video, component interlaced and RGBS interlaced signals.
Range: 0 to 8 Factory Default Setting: 3
Operation: Press
½ button to increase the sharpness.
Press
¼ button to decrease the sharpness.
Á
Note: Increasing the sharpness setting gives the visual effect that the noise filter setting is
decreasing. Although the sharpness and noise filter settings seem to offset each other, they
are actually two different adjustments that affect two different sets of circuitry. Operators
should adjust both settings until optimal picture quality is achieved.
Gamma: The 30 active gamma correction curves programmed into the IN1408 are used to
compensate for the non-linear response of many display devices. Before adjusting Gamma, the
brightness and contrast controls should be set at factory default positions. Once the proper gamma
setting has been achieved, the brightness and contrast settings should then be optimized to fine
tune the image. This control is only available for composite and S-Video signals only.
Range: 1 to 30 Factory Default Setting: 10*
Operation: Press
½ button to step to higher numbered gamma curves.
Press
¼ button to step to lower numbered gamma curves.
9600 The factory default setting of 10 corresponds to a gamma correction curve of 1.0
Noise Filter: Changes the input signal noise filter.
This control is only available for composite and
S-Video signals.
Range: 0 to 47 Factory Default Setting: 9
Operation: Press
½ button to increase noise filter.
Press
¼ button to decrease noise filter.
Á
Note: Increasing the noise filter setting gives the effect that the picture sharpness setting is
decreasing. Decreasing the noise filter will effectively add more image detail. Review the
Sharpness setting section on the previous page.
Comb/Trap Filter: Selects the comb filter, trap filter or turns both off.
This control is only available
for composite signals.
The comb filter electronically provides excellent Luma / Chroma separation (separates the
color from the picture signal). This greatly reduces cross-color interference and hanging dots
while maintaining image bandwidth and detail (applies to composite, S-Video and
Component A signal formats only).
The trap filter extracts luminance from the picture. Generally speaking, the trap filter is
usually the preferred setting when running signals from a VCR (as composite video). You
may wish to compare both settings to determine which is best for your application.
Reset Video Settings: Resets all video settings to factory default (for current input only).
