Matrix Adjustments - Sony BVP-900 Series System Manual

4-12 Matrix Adjustments

This system can use a linear matrix circuit that
compensates the R, G, and B outputs.
In addition to preset matrix compensation with fixed
coefficients, user matrix compensation and multi
matrix compensation are available for use.
The former permits you to specify coefficients for
R–G, G–B, B–R, R–B, G–R, and B–G independently
as desired, and the latter permits you to divide the
entire color tone into sixteen ranges and adjust color
reproduction closely for each range.
The six constants of the user matrix and the values for
the multi matrix are set on the menu operation block of
the MSU-700A/750.
When the preset matrix, user matrix, and multi matrix
are all turned ON, the value of their sum is sent to the
matrix circuit.
What is multi-matrix compensation?
This function enables easy color matching between
cameras or color reproduction to personal preference
by varying the matrix coefficients according to the
color phases. Using this function, you can change the
saturation and hue of a specific color.
This function operates by providing 16 axes in the
direction of color phase on a color plane like a vector,
assigning matrix coefficients to each axis, and linearly
compensating between these axes.
Normally, six matrix coefficients may be required for
each of the 16 axes as with the normal linear matrix.
The multi-matrix compensation of this system can be
easily achieved by operating only the two coefficients,
hue and saturation. Note, however, that as the multi-
matrix compensation is a kind of linear matrix
compensation, the directions of settings for some
colors may seem to be deflected when measuring them
on a vertorscope.

To turn off matrix compensation
Press to light the MATRIX OFF button of the MSU-
700A. When the MATRIX OFF button is lit, all of the
preset matrix, user matrix and multi matrix are turned
off.
When you use matrix compensation, check that the
MATRIX OFF button is dark.
When the button is dark, you can independently turn
on/off the preset matrix, user matrix, and multi matrix
on the adjustment display of the menu operation block.
You cannot turn the preset matrix, user matrix and
multi matrix on the adjustment display all off when the
button is dark. Press and light the MATRIX OFF
button to turn them all off.
When using the MSU-750, you can turn off all of the
preset matrix, user matrix and multi matrix by using
[Matrix Off] on page 2 by selecting [SW] on the
Function menu.
For the Function menu of the MSU-750, see page 4-31.
