Internal Data Stream of black/white cameras
The PCI-Board gets the 12bit data from the camera and trans-
fers it via PCI-Bus to a 16bit array (of the PC Memory). The
higher 4bits are set to zero. The 16bit data are automatically
converted in a 8bit array and accessed by the graphic board.
Depending on graphic board setup display on the monitor is ef-
fected in 8, 24 or 32 bit.
File Formats
The command ‘Export’ stores 16bit or 8bit data on hard disk in
B16, TIFF, FITS, BMP, or ASCII format.
For further information see Chapter 2.3.
Display
The camera which acquires always 12 bit images resolves with
4096 (2E12) grey levels between black and white, however the
monitor display of the image is always limited to 8 bit and there-
fore to 256 (2E8) grey levels.
The command ‘Convert Control’ allows to select a discretionary
range between 0 ... 4095 grey levels which is then displayed in
256 grey levels on the PC monitor.
