Chapter 3 Benefit of Sony ADSP (Advanced Digital Signal Processing) 43HDC-900/950/930 Series Product Information Manual
3-1. Full DSP Camera Processing
The HDC-900 Series uses 12-bit A/D conversion
based on the latest LSI technology. This advanced
technology has allowed Sony to take a major step
forward from the 10-bit conversion of its previous
generation of cameras - a move that was not possible
with earlier A/D converters and DSP LSIs.
(1) Multi Matrix
Multi Matrix is a function that electronically adjusts the
basic RGB color 'taking characteristics' of the camera
to achieve optimum colorimetry. It makes it easy to
match the color of cameras under multi-camera
operations, or to reproduce the characteristics of
another type of camera. It can also be used to
manipulate color for a particular special effect. A
conventional linear matrix function provides only six
adjustable parameters, with considerable interaction
between their effects on a specific color. Multi Matrix
divides the spectrum into 16 segments, each of 22.5
degrees, for each of which there is an independent
hue and saturation parameter. Multi Matrix allows the
selection of each of these segments, with separate
adjustment of hue and saturation parameters.
Operation flow is as follows:
1. Select Multi Matrix on the paint menu of the MSU-
700A/750 Master Set-up Unit.
2. Turn the Matrix and the Multi switches to ON.
3. The MSU-700A/750 EL display now shows a
representation of the Multi Matrix as it would appear
on a vectorscope. You can select the desired color
phase that you want to adjust.
4. After selection of the color phase, its hue and
saturation can be adjusted.
