‎‎‎Fisher information and Kullback-Leibler information which have started to become more common in recent decades, are the criteria for measuring information. ‎N‎owadays,Kullback-Leibler information has become one of the most important criterion in reliability.‎Cumulative Kullback-Liebler information has been recently introduced as a new genetalization of the Kullback-Leibler ‎criterion ‎based ‎on ‎cumulative ‎distribution ‎function.‎ In this stduy, apart from having a review on the fundamentals, the theory of cumulative Kullback-Leibler information is introduced and its characteristics and limitations are mentioned. Moreover, feasibility of applying the dynamic cumulative Kullback-Leibler for past lifetime is discussed. In conclusion, feasibility of utilizing cumulative Kullback-Leibler to measure the levels of gray in images and their resolutions, is proved
