Digital camera is the main medium for digital photography. Digital image takes more memory space and more energy to store, as a digital camera operates on portable battery. Hence, it limits its performance and longitivity. An efficient energy management is required to limit this drawback. This paper proposes a new technique by using Discrete Hartley Transform which will give the same result as that of the existing algorithms with low power consumption.
