3. Setting the conversion table for scaling
The conversion table for scaling is set based on the data table stored in a device specified in [
later.
The data table has the following configuration:
Set item
Number of coordinate points
Point 1
Point 2
Point n (last)
Setting example of the conversion table for scaling
A setting example for the 16-bit operation is shown below.
For the 32-bit operation, set each item using a 32-bit binary value.
In the case of the conversion characteristics for scaling shown in the figure below, set the following data table.
