   - The camera provides video in RAW format, therefore [[http://​en.wikipedia.org/​wiki/​Bayer_filter|debayering]] is needed. This can be done for example by using the following commands. We could not figure out how to change the white balance for blue channel in the MATLAB environment,​ therefore blue channel must be multiplied by an appropriate value <​code>​im_debay(:,:,​1) = im(2:​2:​end,​1:​2:​end);​   - The camera provides video in RAW format, therefore [[http://​en.wikipedia.org/​wiki/​Bayer_filter|debayering]] is needed.

-As described above, it is possible to set some camera parameters in the MATLAB environment. These parameters influence the image provided by the camera, and they are therefore important for the successful use of the camera. Description of paremeters in the camera documentation is very limited. Therefore, we conducted a limited survey and testing in order to determine the possibility set the capturing parameters.+As described above, it is possible to set some camera parameters in the MATLAB environment.

 Unfortunately MATLAB interface allows to adjust only a limited number of parameters. The following parameters can be set: Unfortunately MATLAB interface allows to adjust only a limited number of parameters. The following parameters can be set:
