comment Xenon flash with rolling shutter
specialty of the sensor is that i have them on hand and they are small in size. The module is only 1cm x 1cm in size. This is for work. What kind of continuous light source would you suggest. I would still prefer some kind of strobe, if possible I would like to avoid a off the shelf camera.

@Matt Grum: The internals may not be relevant to this question but I just wanted to understand how a cmos image sensor works.

@Matt Grum: ovt.com/products/sensor.php?id=65 this is the image sensor. I'm using a camera module with this sensor. There's no specific item that I'm taking photos of. I wasn't aware of the rolling or global shutter until the camera's arrived. I'm taking stills but I want to do it in burst mode so maybe its as good as video possibly.

@Matt Grum and mattdm: are there any online references that will enable me to understand the internal workings of a cmos image sensor?

Sorry, I'm a noob in photography, what is sync speed? Is it something related to the flash.

If I do use high speed sync flash, where do I fire. I mean at what position in the image sensor exposure should I trigger the flash and generally what would be the time period of the flash.

comment What is a “4P” Lens?
@Rowland Shaw: trulydisplays.com/ccm/specs/5.0M%20CM5326-B500BA-E%20Spec.pdf Look at page4 in the lens section

comment What is a “4P” Lens?
I'm a bit confused now after reading this, whuber mentions that 4P means a 4 element plastic lens. The datasheet of this particular camera states that it is fixed focus, I don't know about manual focus adjustment and the electronic contacts of AF as said in your answer. What conclusions should I come to?

I may be wrong, but my thinking was that the IR part was a filter attached behind the lens and it was to remove the IR component of light entering the camera.

@whuber: Thanks, so why exactly do we need these four plastic lenses or glass lenses? Is there some reference that explains the construction and understanding of lenses.
