A digital camera coupled with computer has a great potential in an analysis of discharges structures. This work analyzes an approach to visualization of dynamic radiant object. Mapping of brightness uncertainty values is used to show regions of different fluctuation intensity of radiation. The entropy as described by information theory was used as a relevant parameter for an uncertainty value. By a mathematical procedure a relative parameter based on the entropy was evaluated. As result an effects of optics sensitivity or of imperfections of experimental set-up were significantly suppressed.
