Image Adjustment Functions

When you are using the enhanced chroma key function, the following image
adjustment functions are the same as when the BKDS-2032 board is not
fitted: auto chroma key, window, and key position functions. For the
operation of these functions, see page 5-7.
The following procedures are the same in both D1 and D2 systems.
Using a dual key for combining images
By dividing the image into two areas, this function uses two key signals
(main key and subsidiary key) for the different areas.
This allows two different sets of key adjustment values in the same image,
which makes it easier to avoid undesirable effects of variations in the
intensity of the blue background.
Use the following procedure.
