Decoding of images in DR1 cameras
The images arrive in a encoded (compressed) format in the DR1 cameras if
EnDoubleRate
=
True
.
There are functions in the pfDoubleRate package to decode the images. The package
documentation is located in the
SDK\doc
sub-directory of PFRemote installation directory.
Examples are located in the
SDK\Example\pfDoubleRate
sub-directory. The package is installed
with the PFInstaller that can be downloaded from the Photonfocus web page. During the
installation process, the option
DR1 support
must be checked.
There are separate decoding functions for monochrome and for color DR1 cam-
eras.
7.12.1
Status line in DR1 cameras
The newer revisions of the DR1 camera series contain the status line feature (see Section 5.10).
The status line is supported in the pfDoubleRate.dll from the PFInstaller Rev. 2.38 and later.
The whole image, including the status line, can be applied to the demodulation functions. The
status line is copied unmodified to the demodulated image, which is the correct behaviour as
the status line is never sent in modulated format.
7.13
DR1Evaluator
The DR1Evaluator is a tool to evaluate the effect of the encoding algorithm that is
implemented in the DR1 cameras. It is included in the PFInstaller that can be downloaded from
the Photonfocus website.
The main window of the tool is shown in Fig. 7.6.
Figure 7.6: DR1Evaluator
An input file can be selected by clicking on the button
Select Input File
.
Suitable images for evaluation of the monochrome encoding algorithm can be
downloaded from the website http://www.imagecompression.info/test_images.
Download the Gray 8 bit images. The best images for evaluation are the images
that were taken by a camera. The artificial images don’t reflect a "real-world"
situation.
