Image capture ,storage and analysis

Hi everybody,

I have an IR CCD camera (analog) whose output is coupled to a LCd
monitor.

I'm interested in capturing the image , storing and analysing it at a
later time.
I think this is possible by using a frame grabber that can be housed
in a PCI slot of a PC.

This means that i would have to carry my PC whereever i go.
But i would like to know if there is any other product that can be fit
to the CCD camera, capture images say (for 10 minutes or so..)and
store that.

Later on i should be able to download this data to my PC and process
it.

I'm interested in something that doesn't occupy much space and that
can be carried along with the CCD camera.



Do suggest some methods for doing this.
TIA
