Paper Abstract

Eastman Kodak Company has continued the development of a rate-controlled, adaptive Differential Pulse Code Modulation (DPCM) image compression algorithm for commercial remote sensing applications. A version of this algorithm is currently being used in a space-qualified ASIC onboard the Space Imaging IKONOS satellite and Digital Globe QuickBird satellite. This ASIC compresses the raw imagery data (before calibration) at a speed just under 4 megapixels per second. Kodak has redesigned this ASIC to increase the functionality and throughput, while maintaining the power and reducing the size. This new ASIC is intended to meet the future commercial remote sensing requirements for increased resolution and greater area coverage.
