A 640×480 pixels interline transfer CCD with open window ability is designed and fabricated with the pixel size of 7.4μm×7.4μm. The device has four open window modes, including 640×480pixels, 228×480pixels, 640×164pixels and 228×164pixels. The device can output signals in single or dual output channels. When the window resolution of dual output images is 228×164pixels, the frame frequency can reach 500f/s, which meets the application requirements of high-speed target recognition.
