Magic Lantern Interesting Possibles?
« on: February 18, 2012, 09:49:01 PM »

https://groups.google.com/group/ml-devel/browse_thread/thread/dea4ce5e18f9140f/a35d128529b9e90e?show_docid=a35d128529b9e90e
Clean HDMI out may be a possibility???  Read further below.
Speaking of DIGIC - I've found a few image filters in Canon's image
processing pipeline; these can be enabled or disabled very easily. You can
find 3 of them under Movie menu (those are grayscale recording, negative
image, and something that looks like purple fringing).


These functions which use DIGIC registers are found usually by trial and
error (changing the values in these registers blindly and writing down what
they do). There are thousands of registers (many of them unused), so
analyzing all of them by brute force is a huge task. If you would like to
help with this, let me know and I'll prepare a special autoexec.bin (you
don't have to write any code, but you shouldn't be afraid of lockups,
ERR70's and other similar things).


The following functions were implemented by changing DIGIC registers: FPS
override, Highlight++, display saturation, display position adjustment,
custom color palettes, and today, image filters. Other possible
functionality: clean HDMI out, moving the recorded box around in crop mode,
custom curves applied to image, anamorphic preview... etc. The good news is
that DIGIC commands are the same on all cameras.


This can unlock many things that previously were thought to be impossible
or very hard.

Here is what Alex, the Magic Lantern "King", has recently stated:

Looks like we are making progress in understanding how to reconfigure sensor scanning modes, image processing pipeline, output device and so on. No promises for now, just some hope.


Hmmm, things could be heating up very nicely for the dslr people.  "Reconfigure sensor scanning modes" - that sounds very interesting indeed!

Let's hope the Magic Lantern People show up the camera companies in a huge way (they already have but...things may get alot more exciting...). 
Here's some info on sensor and picture image.

Thanks for the info FilmMan.

It'll be interesting if the Magic Lantern Team achieves uncompressed 1080p HDMI out.  If not, it'll be interesting what the video specs of the new Mark 5d iii will be.

For interest sake:

The HDMI output from the Canon HDMI is limited to 1620x1080 (3:2) while the camera is not recording. This requires the user to crop the footage from the external recorder to 1620x910 (16:9) and then resize it to either 1280x720 (79%) or 1920x1080 (119%).
 
When the camera is recording, HDMI output resolution is limited to only 720x480 (effective image resolution is 640x388, which represents a stretched 3:2 frame).

Digic Register Testing:

Looks like fun.  Should I risk my Canon Mark 5d II for science? 



Prediction:  More fun stuff coming...

Just wondering if they did achieve uncompressed hdmi out would it be 4.2.2 or 4.2.0?
