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.
Setting the conversion setting data table for scaling
*1. When coordinates are specified using three points as shown in the points 4, 5 and 6, the output value
can be set to an intermediate value.
In this example, the output value (intermediate value) is specified by the Y coordinate of the point 5.
If the X coordinate is same at three points or more, the value at the second point is output also.
*2. When coordinates are specified using two points as shown in the points 8 and 9, the output value is
the Y coordinate at the next point.
In this example, the output value is specified by the Y coordinate of the point 9.
