Abstract
Visual images are essentially important in space systems not only for simple monitoring but also base of various kind of sensing. Previously, camera systems and image processing units used to be designed separately. Compact image acquisition and processing systems with high performance can be obtained by integrating image processing units into cameras. We have developed a compact, multi functional, integrated image acquisition and processing unit. This unit comprises a CMOS image sensor, SDRAM, flash memory, and an FPGA that includes a CPU core. The unit is less than 70 mm cube and its weight is less than 300 g. It can perform image acquisition, and multifunctional image processing and compression; the compressed images can be decompressed flexibly as required. In this paper, we present an outline of the image acquisition and processing unit.
