Lucis^® Image Processing Software, an easy, fundamentally new way to view image content

Images often contain hundreds to tens of thousands of contrast levels. Our eyes can only differentiate 32 levels of contrast. Therefore fine contrast variations are only partially recognized as textures our eyes can't resolve.

Lucis^® makes visible the fine contrast variations (details) you would like to see.

Using two cursors (sliders) in Preview Mode, select the range of contrast variances to view. Lucis compares each pixel to every other pixel along hundreds of radial lines in two directions to map out contrast variances. Contrast variances within the selected range are enhanced and contrast variances outside the range are diminished. The relative emphasis of contrast information is shifted, but information is not thrown away. Lucis reveals detail that other image-processing methods can’t.

Lucis reveals detail throughout the image, in both the bright and dark areas

The single-luminance-channel Lucis image most clearly defines the transparent reticulum of the cell and reveals details within the dark central mass of the chloroplasts.  Lucis most fully reveals the full extent of the central fissure that divides the mass into two halves and shows details, such as varicosities, within the transparent strands.

Lucis processing only effects the intensity information in an image. To process a color image, Lucis converts the RGB (Red Green Blue) information to HSL (Hue Saturation Luminance).  Lucis processes the Luminance information, and then combines the new Luminance (L') with the unaltered Hue and Saturation. The HSL' information is converted to RGB.  Color images will experience color shifts as Lucis extracts the image detail.

Lucis 4.2.1 processes color images as single luminance channel images.

Lucis Pro 5.0 allows the user to process each RGB channel separately with differing Lucis processing parameters, so the details in each color can be seen as clearly as possible. This is essential for applications like Fluorescence Microscopy.
