These are the sections I've been playing with:


cam_ss_jpeg_buffer_size_1=249F0; // 150 KB buffer for 640x480 snap
cam_ss_jpeg_buffer_size_2=61A80; // 400 KB buffer for 1280x960 snap
cam_ss_jpeg_buffer_size_3=927C0; // 600 KB buffer for 1632x1244 snap
cam_ss_jpeg_buffer_size_4=DBBA0; // 900 KB buffer for 2000x1500 snap
cam_ss_jpeg_buffer_size_5=DBBA0; // 900 KB buffer for 2048x1536 snap

AND:

seq_set_prop_5_9 = $"3M_low_comp"
#SET_REG(19,5F) // JPEG_INIT_QUALITY = 0x5F = 95d
#SET_REG(13,84) #SET_REG(14,03)
#SET_REG(17,20) #SET_REG(18,03)
#SET_REG(15,58) #SET_REG(16,02);

Also, I'm quite certain the jaggedness is not just my phone. The stupid thing is that it doesn't always happen. Try taking pictures of the edge of a sheet of paper at a 45 deg angle or a barcode at 45 degrees

I managed to recreate the effect on a bar code, but only by washing the picture out with reflected flash.

You can see my results on flickr:

But it proves the affect is an inherent characteristic of the hardware. It deserves continued investigation to find out what conditions specifically are causing the effect.

btw, thanks for that code

These are buffer size limits. Play with them around and check if your phone can handle 1 MB buffer or more the more buffer size the phone can handle the lower compression you can use

Increased my buffer to 1MB, compression to 95%

This is a crop of a 90% picture (stock Driver):


This is a crop of a picture using 95% driver:


Now, at first glance the 95% driver seems a lot clearer, and this is exactly what I am hoping less compression can achieve. But before we get excited, I'd like to do more testing to ensure this result is easily repeatable.

I have played with the buffer size. I've been able to set the buffer to 1.5mb with no problems. The catch is you can't even set the max image size to 950 without making the camera instable.

I've got a 98% driver in at the moment, with only 1MB buffer, it seems to be working okay. But I have yet to take a lot of photos with it.
