Turn on to use a set of coefficients
based on the preset color model
conversion you then choose from
the drop-down list:
- Studio Video RGB to YCbCr
- YCbCr to Studio Video RGB
- Computer RGB to YCbCr
- YIQ to YUV
- YUV to Computer RGB
- Computer RGB to YUV
Turn off to edit the floating-point
value of each coefficient of the color
space conversion equations.
See
more information on color model
conversion.
Allows you to convert the
floatingpoint coefficients defined
above to fixed-point coefficients
using the number of bits of precision
that you specify. This conversion
consists of multiplying all the
floating-point coefficients with a
common scaling factor and casting
the floating-point multiplication
result to a two’s complement integer
(a fixed-point coefficient). The
scaling factor is defined so that the
floating-point dynamic range (min-
max value) gets mapped to the
coefficient bit-width dynamic range
(min-max).
Turn on to round the scaling factor to
the nearest power-of-two integer
value
Turn on to set the scaling factor to
1.0
