1 Real time RAW preview

2 Approaches:

  • Read raw bayer pattern data and reduce resolution with pixel skipping (every 2nd, 3rd, 4th, etc. pixels) then do debayering in GLSL shader. We already have the python written Stereocamcheck software that uses GLSL shaders to debayer JP4 RAW in real time. The footage is read via Gstreamer.
  • Read raw bayer pattern data and generate RGB values from 2x2 photosite block which contains 2 green, 1 red and 1 blue value. This automatically reduces the resolution by half in both horizontal and vertical axis. Further resolution reductions could be done by skipping every 2nd, 3rd, etc. 2x2 photosite block.
