True Color Overview
The True Color method reads color measurements from hyperspectral data and creates a true color image from this information.
This method only works for the visual range, if the data set does not contain information in the visual range, then the output image stays black as no useable information is present.
The user has options to change:
- Observer Function: simulated angle of view
- Illuminant Function: type of simulated lighting conditions
- Color Format: the color format of the output image. Note, that only sRGB will produce visually matching colors.
Color Formats & Streams
There are three color formats, which are, sRGB, XYZ ang Lab. Each format has its own value range. A True Color model can be applied to a perception core as configuration. In this case, the user can select the bitdepth of the stream (either 8bit or 16bit). Depending on the bitdepth, the range of the ostreamed values is scaled to fit the possible range. This is explained below, for each of the color formats.
