N.1.1 Setting the Permitted Ranges
The permitted ranges of the different colour components are part of overall Video configuration, set
on the Video page of the Configuration window (see Section B.2.1). The
Ultra
is delivered with the
various maximum and minimum values set in accordance with standard practice within the industry
but the user is free to set their own choice of values.
Separate settings are made for the YCbCr and RGB colour spaces. The section of the Video page
where these settings are made is shown below:
Figure N-2: Gamut Range section of Video page of Configuration window.
The display is divided into separate sections covering YCbCr and RGB colour spaces.
The YCbCr section allows you to set separate maximum and minimum values for the luma and the
chroma elements. The RGB section sets a single range of permitted values to apply across all three
colour components. The values are all expressed as decimal values.
The first line of each group is used to specify the percentage of the image which needs to be out of
range before an error is reported.
N.1.2 Selecting the Colour Components to be Displayed
The range of colour components for which bar graphs are displayed is
controlled through On( 1 )/Off( 0 ) selectors shown in the right-hand
panel when the Gamut Meters view is selected.
