apertus° AXIOM Alpha utilizes an image sensor from CMOSIS that has 4K resolution and Super35 dimensions with a global shutter.
AXIOM Alpha though down-samples this resolution internally and outputs a clean uncompressed Full HD signal. AXIOM Alpha itself does not record footage though. You can capture single still images in full resolution in raw uncompressed format. We did not install an optical low pass
filter in front of the sensor and the infra red cut off filter has to be screwed on the lens. Camera control is possible through USB 2.0 or Ethernet interfaces to send commands to the camera and receive information back.
AXIOM Alpha does not record sound and is not able to record RAW video. You can use any HDMI recorder of choice though and most of these also have audio inputs.
By using a debayer algorithm that generates RGB values of a single pixel from a 2x2 photosite (RGBG) block we go from 4K to 2K and from raw bayer-pattern to RGB in a single processing step
(see illustration on the left).
