1 Overview
Simplified: The AXIOM Recorder is a small computer connected to the AXIOM Beta via HDMI, we use the HDMI video stream to transport our own custom raw image data from the camera. This stream needs to be repacked or post processed on the AXIOM Recorder to acquire the actual raw image sequence (RAW12 sequence).
Technical: On the AXIOM Beta we utilize a Full HD (1920 x 1080) HDMI output stream with twice the frame-rate to store 4 pixels (12 bit each) from the image sensor (sensels) in 2 RGB pixels (24 bit each) in the HDMI stream. After recording this data through a HDMI capture device like the Magewell HDMI USB3 Gen 2 on a PC, Laptop or Single Board Computer (SBC) the data needs to be post processed to obtain the original raw data from the image sensor again. The two HDMI images from a single raw image are called A-Frame and B-Frame.
