This camera utilizes Kodak KAI-0340  an interline transfer CCD with 640(vertical)480(horizontal) pixels. Two output ports are used to read out CCD data and pixel rates approaching 30 MHz. Because of its reduced effective opacity of vertical charge transfer registers  interline transfer CCD can cause undesired image artifacts  such as random white spots and smear generated in the registers. To increase frame rate  a kind of speed-up structure has been incorporated inside KAI-0340  then it is vulnerable to a vertical stripe effect. The phenomena which mentioned above may severely impair the image quality. To solve these problems  some electronic methods of eliminating these artifacts are adopted. Special clocking mode can dump the unwanted charge quickly  then the fast readout of the images  cleared of smear  follows immediately. Amplifier is used to sense and correct delay mismatch between the dual phase vertical clock pulses  the transition edges become close to coincident  so vertical stripes disappear. Results obtained with the CCD camera are shown.
