Since I didn't get any answer from my last posting about
electronic shutter, I guess I asked the wrong question.
Ok, let me ask another question first. For
people who used CCD cameras before, did your camera has
a shutter? If it is, what kinds of shutter is it? How
about telling me the type of sensor that is in the
camera (such as interline, frame transfer, full frame, etc.)?
What is the resolution? I hope I can get some feedback this
time because I really need the info.

For some of you who may have the luck to work with CCD
sensors, I have a simple question. I am planning to use
one of those full frame CCD area sensor for a camera.
I forget the part number but it is from TI and it is a
small resolution sensor (something like 190x200, something
around there). If I clock the sensor in maximum allowable
speed and use it without a shutter, will I get smear
image due to the shifting of charge from top to bottom?
I am hoping that the readout will be fast enough so the
accumulation of charge will be small.

Any help will be appreciated. Thanks in advance.
