PhotoRetouch Pro includes several binuscan technologies. Among these:

CDC 4x

Alongside the conventional interpolation algorithms, bi-cubic, bi-linear and nearest neighbor, PhotoRetouch Pro offers an additional method, called CDC 4x.

The "4x" indicates that it is designed for factor 4 enlargements (i.e. 200% horizontally and 200% vertically). CDC 4x is an enlargement technology, similar to a slide in a slide projector: the farther the projector is placed from the screen, the larger the image will be. Yet, it remains the same image. Images enlarged with CDC 4x retain the original pixels, thus they retain the same look and feel as the original, which is simply enlarged.

This enlargement technique does not generate noise and does not result in jagged edges. Images are enlarged but so are defects. Two consecutive CDC 4x enlargements generally yield excellent results if the original image quality is high.

Pyramidal Image (bTIFF)

A pyramidal image is a TIFF with a pyramidal structure that can be viewed with any image editing software as if it were a regular, "flat" TIFF.

With this exclusive optimization technology, all navigation, zoom and opening operations are greatly accelerated while retaining an optimal on-screen rendering. The monitor image is always optimized for the best possible use of the original pixels. Whenever the user is satisfied with his (or her) selection and enlargement, the cropping itself is applied on the selected area.

The cropped portion of a pyramidal image becomes a new image by itself, inheriting and preserving automatically the pyramidal structure. This mecanism is called pyramidal inheritance. With the help of this technology, it is always possible to zoom, crop or navigate in the “daughter” file, with no loss of quality.

When an image needs to be saved after minor retouching, only modified portions of bTIFF images need to be saved, not entire image files.
