A planned feature is to generate this FPGA code block with "dynamic reconfiguration" meaning that the actual debayering algorithm can be replaced at any time by loading a new FPGA binary block at run-time.
This tries to simplify creating custom debayering algorithms with a script like programming language that can be translated to FPGA code and loaded into the FPGA dynamically for testing.
Peaking marks high image frequency areas with colored dot overlays. These marked areas are typically the ones "in-focus" currently so this is a handy tool to see where the focus lies with screens that have lower resolution than the camera is capturing.
Handy Custom Parameters:
Digital zoom into the center area of the image to check focus.
As extra feature this zoomed area could be moved around the full sensor area.
This feature is also related to the "Look Around" where the viewfinder sees a larger image area than is being output to the clean-feed.
This re-sampling method to scale up/down an image in real-time can be of rather low quality (nearest neighbor/bilinear/etc.) as it is only for preview purposes.
scn_reg 28 0x00 # deactivate clipping
scn_reg 28 0x10 # activate low clipping
scn_reg 28 0x20 # activate high clipping
scn_reg 28 0x30 # activate high+low clipping
At this moment we were able to reuse an Arch Linux image for the Zedboard on the Microzed. To do so, some software such as the FSBL and uboot were added. More information can be found here: http://stefan.konink.de/contrib/apertus/ I will commit myself on the production of a screencast of the entire bootstrap proces from the Xilinx software to booting the MicroZed.
I would suggest running Arch Linux on the AXIOM Beta for development purposes. If we need to shrink it down that will be quite trivial. Obviously we can take the embedded approach from there, as long as we don't fall in the trap of libc implementations with broken threading.
--rnfilter=1 : FIR filter for row noise correction from black columns
--rnfilter=2 : FIR filter for row noise correction from black columns and per-row median differences in green channels
--fixrn : Fix row noise by image filtering (slow, guesswork)
--fixpn : Fix row and column noise (SLOW, guesswork)
--fixrnt : Temporal row noise fix (use with static backgrounds; recommended)
--fixpnt : Temporal row/column noise fix (use with static backgrounds)
--no-blackcol-rn : Disable row noise correction from black columns (they are still used to correct static offsets)
--no-blackcol-ff : Disable fixed frequency correction in black columns
Flat field correction:
--dchp : Measure hot pixels to scale dark current frame
--no-darkframe : Disable dark frame (if darkframe-xN.pgm is present)

--no-gainframe : Disable gain frame (if gainframe-xN.pgm is present)
--no-clipframe : Disable clip frame (if clipframe-xN.pgm is present)
--no-blackcol : Disable black reference column subtraction: - enabled by default if a dark frame is used. - reduces row noise and black level variations
--calc-darkframe : Average a dark frame from all input files
--calc-dcnuframe : Fit a dark frame (constant offset) and a dark current frame (exposure-dependent offset) from files with different exposures (starting point: 256 frames with exposures from 1 to 50 ms)
--calc-gainframe : Average a gain frame (aka flat field frame)
--calc-clipframe : Average a clip (overexposed) frame
--check-darkframe : Check image quality indicators on a dark frame

--fixpn-dbg-noise : Pattern noise: show noise image (original - denoised)
--fixpn-dbg-mask : Pattern noise: show masked areas (edges and highlights)
--fixpn-dbg-col : Pattern noise: debug columns (default: rows)
--export-rownoise : Export row noise data to octave (rownoise_data.m)
--get-pixel:%d,%d : Extract one pixel from all input files, at given coordinates, and save it to pixel.csv, including metadata. Skips DNG output.
