Sounds good, but i can't access the diff (The file you are trying to access is temporarily unavailable)

Edit: While don't you attach a zipped source-diff to your post?

Download the patch worked for me also from another computer. Interested..

I tested your new-edge detection on my SX20 IS firmware version 1.00F, with the following result:

1. The new edge-detect is works continuously when i press half the shoot button. (the old worked only when i released the half-shoot) Therefore it's looks like faster. :)

2. The save crashes the camera (the old worked well)

3. The filter option works very well! (gives fine result on noisy scenes)

Keep up the good work!

Do you like the new behavior or should I change back? I decided to only display the edge overlay when the shutter is half-pressed because else it overwrites everything on the screen. This way you can reenable other OSD elements by simply releasing the button. But if you people like the old behavior better, I can change it back.

Thx for reporting and testing. I fixed it now and the diff file in the original post is updated with the fix. It doesn't crash now.

Does this "continuous" mode display the edges in real-time? If so ... this will be a boon to all macrophotographers. Something similar was implemented in early Sony cameras. As a way to detect which edges are in sharp focus, highlighting them. I use a similar principle for manual focus for macro-photography. Whatever pixels in the EVF are scintillating with slight movement of the camera, I know those edges, areas, and textures are in sharp focus.

No, i am not an edge-detect user, so i just noticed this change. However it seems better than before. (looks more user friendly)

Now, i can't save, because the edge data disappears where i press the menu button, so no overlay to save.

P.s.: If you make diff, try to step one directory inner, so your diff should begin with

Code: [Select]
Index: include/conf.h
===================================================================
--- include/conf.h      (revision 924)

@@ -250,11 +250,12 @@

instead of

Whatever pixels in the EVF are scintillating with slight movement of the camera, I know those edges, areas, and textures are in sharp focus.

I was already thinking about a menu option that would make the overlay display continuously on the screen without having to press the shutter button. So this seems like a good suggestion. However, I personally do not think that that this edge overlay is suitable for focus adjustments. This is because the edges drawn are too thick. I use it for panoramas and stereo photographing, not for macrophotography. Maybe, if you could try out the patch, can you tell me if it's suitable for the macro-users?

The whole reason I opened this topic is because I want to perfect the patch before submitting it for inclusion in the trunk. If you have *any* suggestions, please don't hesitate to post.
