Parts of the ISP are blackboxes (debayer), other parts are quite trivial and documented in a bit more detail (gamma/degamma, BLC, color matrix transformation, etc.) and some parts are a bit of a mix. The documentation is spread over many PDFs, incl. from different venors who use the same ISP like NXP, who tend to document things in a bit more detail. So at worst, it's a gray box. ;)
