Pictographics® Color CorrectPoint-and-Click White Balance, Exposure, and Skin Tone Correction
The Color Correct Library is the color engine behind PictoColor's award winning iCorrect Portrait color correction Photoshop Plug-in. iCorrect Portrait is the fastest and easiest way to make every portrait more life-like. With just a few clicks, you can instantly correct the white balance, exposure, and skin tone of any portrait. With iCorrect Portrait, you can easily remove any color cast, correct the tonal range, adjust the brightness and contrast, and give every skin tone the color of life.
Pictographics Color Correct technology creates a color correction “profile or
function” by direct analysis of a digitized image. The
correction profile is based on associating color groups of the original
image with color groups obtained either from reference images or
mathematical color models. Once the color correction profile has
been made, it may be applied to the original image or any other images
needing the same correction. The technology uses an approach to
color editing that allows direct interaction with the image or, in many
situations, totally automates the color correction process. In
either case, the image may be easily and accurately corrected in a very
short time, without repetitive steps or trial-and-error methods.
Correct technology was developed by Pictographics International
Corporation. The technology is licensed to digital
imaging software developers, system companies, hardware manufacturers,
and Internet based imaging services under Pictographics
Technology License Agreement. It is available as a library or DLL.
to the whole library’s approach to color correction is the notion of a
colorimetric monitor RGB. Much
like the RGB working space found in Adobe Photoshop, the library
requires the RGB system to have an unambiguous colorimetric meaning by
tying it to the CIE color system. This allows the color correction to
have meaning to other programs afterward, and it also allows for the
possibility of properly displaying the color image for the user by
taking into account the monitor profile.
library has the ability to create correction functions that map selected
RGB colors into a form that matches a predefined memory color
definition. For example,
the library has built-in, device independent definitions for a few
common colors, such as skin tone, foliage and neutrals. Colors from the
image, when interpreted to device-independent color through the monitor
parameters, may be made to align with corresponding definitions by
applying the proper transformation.
This transformation is computed automatically by the library.
colors are taken from a low resolution representative of the full
resolution image by using user-selected “marks”, or pixel
coordinates as seed points from which similar colors are contiguously
collected. Each mark is
associated with a particular memory color definition, allowing the
memory color correction to take place.
Color Correct technology is the foundation of PictoColor's iCorrect Portrait Photoshop Plug-in.
