Runco SC-50D, SC-60D operation manual Calibration

Operation

Use the Calibration menu to perform advanced picture quality adjustments. This menu should be used by ISF-certified technicians only.

You must enter a passcode to access the Calibration menu.

Note

To recall the ISF Night or ISF Day settings, select “ISF Night” or “ISF Day” from the Memory Presets menu (see page 62) or use the corresponding remote control buttons.

Display Color: Use the Display Color settings to adjust the color balance at the DHD Controller output. These settings are saved independently for each input and display mode.

•Gain: Use the Gain controls to correct color imbalances in the bright areas of the image. A good way to do this is to use a test pattern consisting mostly of solid white areas, such as an 80 IRE “window” pattern. If the white areas contain traces of red (Pr), green (Y) or blue (Pr), decrease the Gain for that color.

•Offset: Use the Offset controls to correct color imbalances in the dark areas of the image. A good way to do this is to use a test pattern consisting mostly of dark gray areas, such as a 30 IRE “window” pattern. If the gray areas contain traces of red (Pr), green (Y) or blue (Pr), decrease the Offset for that color.

•Gamma: Select Gamma from the Display Color menu to choose a de-gamma curve. Used correctly, the Gamma control can improve contrast while maintaining good details for blacks and whites. If excess ambient light washes out the image and it becomes difficult or impossible to see details in dark areas, lower the gamma setting to compensate. This improves contrast while maintaining good details for blacks. Conversely, if the image is washed out and unnatural, with excessive detail in black areas, increase the setting.

•Mode: With the SC-50d/SC-60d, two Gamma adjustment modes are available: Simple or Advanced. The two modes are mutually exclusive; when you select the Simple mode, the Advanced selection in the Gamma menu is grayed out. Likewise, when you select Advanced, the Simple selection is grayed out.

•Simple: Use the Simple Gamma control to perform gamma correction at the display according to a simple power law gamma function. The value chosen here corresponds to the power variable in this equation:

Output = InputPower

The DHD Controller applies this gamma curve to all three primary color channels (red, green and blue).

•Advanced: To select a custom gamma curve, select Mode from the Gamma menu and set it to Advanced. Then, select Advanced from the Gamma menu to select one of up to 20 pre-programmed gamma tables. Custom gamma tables provide the ability to perform complex, non-linear gamma correction on each primary color channel independently of the others.
