SYNOPSISdconvlum in-file out-file [ambient]
DESCRIPTION
Command line program that converts VeriLUM file with characteristic
curve data (CCx_xx.dat) to a format used for the Barten transformation
in this toolkit. VeriLUM is a calibration package from ImageSmiths
consisting of a photometer (with serial RS232 connector) and a Windows
NT software.
PARAMETERS
in-file VeriLUM characteristic curve file to be converted
out-file DCMTK display file to be written
ambient ambient light (cd/m^2, floating point value)
NOTES
The output file describing the characteristic curve of a display system
(monitor) is a simple text file. Lines starting with a '#' are treated
as comments and therefore skipped as well as blank lines. This
conversion program creates such a file automatically (including some
comment lines) by transforming the information stored in the VeriLUM
file. The number following the magic word 'max' defines the maximum DDL
value (e.g. 255 for 8 bit displays). This definition is required before
the luminance data can be defined. Optionally the ambient light value
can be specified in this file too. The floating point value (in candela
per square meter) must follow the word 'amb'. Finally the luminance
values are defined for each corresponding DDL (device driving level)
value. The entries do not necessarily have to be ordered or complete,
i.e. there can be less than 'max' + 1 entries. Missing values are
calculated by cubic spline interpolation.
See DICOM standard part 14 for more details on display calibration and
Barten's model (including GSDF).
