This provides a windowing function that enables the user to specify which of the available
data bits are output. The bit number specified for LSB is zero-based
– i.e., the least
significant bit in an 8-bit word is bit 0 and the most significant bit is bit 7.
NOTES:
1.
The maximum bit depth setting is “8” if using a single-head controller and
outputting “processed RGB data”.
2. The data is compressed into an integer and is broken into two characters. The
leftmost 8 bits express the bit depth in binary (8, 10, or 12) and the rightmost 8
bits express the LSB position of the bit depth.
Examples: 0x0804 represents 8 bits LSB in position 4
0x0A01 represents 10 bits LSB in position 1
.
BlueGain: (R/W) This feature sets/returns the blue analog gain value for the camera (or tap
where appropriate). The sensor tap is set by the SensorTapReadout feature. Min: 1, Max:
63
Brightness: (R/W) Reads/writes the brightness or offset for the currently active Head to the
specified value in DN counts. Min: 1, Max: 255
CamPixClkFrequency: (Read) Returns the current pixel clock frequency in MHz for the active
camera. Min: 0, Max: 40
CamPixClkSpeed: (R/W) The camera provides user-selection of clock speeds. The camera
supports more than one pixel clock selection. The camera provides the user with the option
to run the sensors at different speeds to accommodate variations in framegrabbers or
application requirements. The actual pixel clock frequency can be determined with the
CamPixClkFrequency. Low/High
