Abstract :
An optimized design for capturing still images from a high altitude balloon flights has been developed. The architectural models produced are well suited for FPGA implementation, which has been the ultimate goal of the authors. The models have successfully achieved the requirements of hardware implementation, where the number of calculation, especially the multiplications, involved in transformation has been reduced significantly.
