How Can I Change Image Interpolation Quality?

The RamSoft software provides two interpolation techniques.

Cubic Interpolation renders the best images, however it is the most complicated algorithm and will require the most computing power. Linear Interpolation provides lesser quality, however it provides better performance.

The software allows the user the choice of one interpolation technique for displaying still images and another for displaying motion for tasks such as Cine and the interactive Unsharp Mask. Still images can also be displayed without any interpolation scheme by using the Pixel Size display option.

The default technique for Interpolation is Cubic Interpolation, whereas for Fast Interpolation, the default technique is Linear Interpolation.

The Interpolation field refers to the interpolation technique used when displaying still images, while the Fast Interpolation field refers to the scheme used for motion. If the display of still images is taking too long, the Interpolation value can be reduced to see if performance will be increased. This will however reduce image quality, so these two offsetting factors have to be considered when changing algorithms.

Similarly, if the quality of the motion images is poor, it can be increased by changing the Fast Interpolation value. However, this will result in a heavier load on the machine displaying the images and can result in performance loss.
