3 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.
