html=2 gets only sensor parameters or FPGA parameters too? For example, it includes P_CLK_FPGA. Is it a FPGA or Sensor parameter?

There is no clear separation between the sensor and the FPGA parameters. I.e. in model 313 sensor driver was taking into account FPGA clock frequency while calculating and setting the "virtual frame height" that limits the frame rate. In the 333 it is currently not needed as the compressor is faster than the sensor in all modes, but the new Micron 5MPix sensor is again twice faster than previous ones - in has 96MHz pixel clock ...

May be dv (not dl)?

Sure, you are right.--Andrey.filippov 09:54, 12 October 2005 (MDT)

Can I use new decimation's values only with 333 camera or with 313 camera too ? Did change the algorithm of the calculation of values WW, WH, WT and WL after decimation?

--Alexlp 13:42, 16 October 2005 (MDT)

All the decimation values (1-2-3-4-5-6-7-8, not just 1-2-4-8) are available for the Micron MT9T001 3MPix sensor, so it can work with 313 hardware too. *But* - I haven't updated sensor driver for the 313 and these modes are now supported only on the 333 camera.--Andrey.filippov 12:37, 17 October 2005 (MDT)

What about rscale, bscale, sens?

gamma values

It looks like the documentation has a bug: The gamma values (gam) as found in the documentation seems to reach from 0.16..10. I'm not sure, but I think this must be more something like: 1..100 or something? Actual useful range is ~0.4 - 1.0, 1.0 being linear (in absolute values) or 40-100% --Andrey.filippov 20:46, 12 March 2006 (CST)
