Some more sorcery, colors are now converted correctly and with some group efforts, the screen is now continuously pulled and dumped trough a pipe in to VLC player for live preview.

Night as Canvas


Light painting with CHDK. Title: Logic of the XOR Gate.

Starry Sky


Night photography with CHDK. Orion with the glow of a distant city in the background. Turns out that even in 30 seconds stars themselves move across the sky enough to blur the picture.

Fun With Protocols


Playing with the CHDK, pulling preview screen frame buffer trough USB cable with ptp and saving it as a picture (using python and openCV).

The colors are off since the camera uses YUV and the pictures are RGB. Conversion needed, but the process works.

Now, colors on the other hand ...

Buffers and Pointers


One of the last buffer addresses traced down! Fast motion detection now works. Although using a stand might improve results here.

More Data per Picture


Saving RAW images works! For comparison (top->down): RAW photo, JPG produced by camera, manually manipulated RAW photo.

P.S. Photo taken at night with 15 second exposure on ISO 400.
