Subject: converting RGB to L*a*b standard

I was wondering if anyone can tell me how to convert raw RGB
values into L*a*b standard. We have the data from Photoshop as
RGB and dont want to reanalyze the samples (well over 1000
pictures). If someone knows of a conversion program etc... it
would be appreciated.

I do understand that different RGB values from different machines
will cause variation in the L*a*b values. But actually that is part of
the question that we are interested.

Thanks.
