Conventional cameras have their own software ISP functions to perform in PC instead of using commercial ISP chips. However these methods have problems such as large computation for image processing. In this paper, th authors proposed ISP that significantly reduced chip area by efficiently sharing of hardware and software. Large operation blocks are designed to hardware for high performances, and hardware is imployed simultaneously with software considering the size of the hardware. The implemented ISP can process Video Graphics Array (VGA) (640 * 480) images and has 91 450 gates size in 0. 35 μm process.展开更多
We fabricated a phase modulator with significant phase shift for TE mode but negligible for TM mode. The measured phase shift efficiency was 7.9°/V.mm for TE mode. No modulation was observed for TM mode.
