HSCF (Vertical SCale Fraction)
The decimal part of a horizontal upscaling/downscaling ratio is set.
HSCI (Horizontal Scale Integer)
The integer part of a horizontal upscaling/downscaling ratio is set.
VSCF (Vertical SCale Fraction)
The decimal part of a vertical upscaling/downscaling ratio is set.
VSCI (Vertical SCale Integer)
The integer part of a vertical upscaling/downscaling ratio is set.
Note:
- Smooth continuation operation to Down Scaling mode and Up Scaling mode cannot be
performed. The picture disorder of some arises at the time of a change. This is the
restrictions for Up Scaling mode and Down Scaling mode using the same interpolate circuit.
