An study of removal of subjective redundancy in JPEG for low cost, low power, computation efficient circuit design and high compression image

As the circuit complexity is increasing in demand for the more computations on a single VLSI chip, low power VLSI design has become important specially for portable devices powered by battery. Digital camera is one of them where realtime image capturing, compression and storage of compressed image data is done. Most of the digital camera implement JPEG baseline algorithm to store highly compressed image in camera memory. In this paper we report and present low cost, low power and computationally efficient circuit design of JPEG for digital camera to get highly compressed image by exploiting removal of subjective redundancy from the image.
