Paper Abstract

An image quantization and mixed-signal processing technique presented in this paper significantly increases speed and resolution of image digitization while consuming minimum energy. It also performs image compression in the mixed signal domain. This has been achieved by exploiting strong correlation between neighboring pixels within each frame and between successive frames. The correlation is utilized by adaptive combining of several quantizers with different sampling rates and numbers of bits and by quantizing the entire image in a small fraction of frames while generating only discontinuity signals in the rest of the frames.
