Adjusting Black Levels And White Levels Using The Peak Detector - Runco Signature Cinema SC-1 Owner's Operating Manual

• Peak Detector: The Peak Detector is a tool to assist with defining individual input
levels, enabling you to accurately set the white balance for any particular source with
the appropriate image.
Enabling the Peak Detector activates a special operating mode for detecting only pixels
that are considered black or white; all other levels are displayed as a mid-level gray.
When used with a smooth grayscale pattern in which black and white are known to be
at opposite edges of the image, you can watch these isolated areas while adjusting
individual black and white levels until both black and white edges are just visible and
distinguished from neighboring pixels. Images from this source will then display correct
blacks and whites without crushing.

4. For the current color, adjust its corresponding "Black Level" slidebar just until a single
band of black appears at one edge of the screen. This band represents the first band of
the grayscale pattern, which should be 100% black. Do not adjust too far.
5. With the same color still active, adjust its corresponding "White Level" slidebar just until
a single band of color appears at the opposite edge of the screen. This band
represents the last band of the grayscale pattern, which should be 100% white (or the
current color, if a certain color is enabled). Do not adjust too far.
