Hi,
A test version in attachments.

The capt_seq.c is based on ixus310 code.

Thank you for the test file.    Not sure what I need to do with the patch file - I assume it is already incorporated into the test chdk code.


I am trying to get to DNG 1.1, but I need to create the bad pixel file first.   When I try to create that bad pixel file, it  fails every time.  Or, loops over and over. 


So I forget trying to set dng 1.1  and leave it at DNG 1.3  - that is unfortunate.


Then I tried long exposure without timer or intervalometer:


- dark frame off - no noise reduction occurs - good!
- dark frame on - noise reduction occurs  - good!


Then I tried long exposure with timer or intervalometer:


- dark frame off - no noise reduction occurs - good!
- dark frame on - noise reduction occurs! - ***very good!***


I will try again to see if I can generate a badpixel file so that I can use DNG 1.1


This is definitely good progress - Thanks!




note - tried again to create that badpixel file and failed.

Yes, the patch is for other developers to look at if they want.

I would be surprised if these changes made badpixel.bin generation fail, but you could try going back to the autobuild to test. badpixel.bin generation failing somewhat randomly on some cameras is an issue that has been around for a long time. It's possible you will have more luck if you take a few shots manually first to let the sensor temperature stabilize a bit.

Went back and loaded the autobuild - no problems creating the badpixel file.


Loaded the new test version again - can't build the badpixel file.   The script itself seems to behave differently (erroneously)

Interesting. Can you report the free memory value shown by "Miscellaneious->Show Memory Info" for both builds.

Are you running a script, or using the built in badpixel.bin creation option in the raw menu? The script is obsolete and should not be used.

What is the output when you try to create badpixel.bin? If it disappears too quickly, you can see it in
"Miscellaneous->Console->Display last console"

When it succeeds, it should show the number of badpixels. It would be helpful to know that, as well as the output in the case it doesn't work.

Under the Raw menu, I am using 'Create badpixel.bin'

For the test code:

Free Memory: 608824 bytes
CHDK size: 134404 bytes
loaded at: 0x1774ec

Under Console:
Wait please...
This takes a few seconds,
don't panic!
badpixel.bin failed
Please try again

For the autobuild:

Free Memory: 581040 bytes
CHDK size: 133748 bytes
loaded at: 0x1774ec

Under Console:
Wait please...
This takes a few seconds,
don't panic!
badpixel.bin created
Bad pixel count: 11417

Hi, a new test file (version 3), this time boot.c was rewritten using code_gen.c to use the patch in other firmware versions.
Please test and report.

Thanks for the new version.   I tested version 3 - and there are some issues:


I can create the bad pixel file - which is good
However, once again dark frame noise reduction on long exposures fails when the timer is used - this is bad.


Correction - it fails when dfnr is set to 'auto' and timer is used.  (even though dfnr occurs when timer is not used)
So, I can force the dfnr to occur by setting the mode to 'on' but 'auto' doesn't do it.
Not a huge issue, just a little strange.
