C10 Increasing Sensitivity with Binning
Binning increases the camera’s light sensitivity by decreasing horizontal and vertical
resolution—the charge collected by adjacent pixels is added together.
To enable 2x2 binning, use the command
set_binning_horizontal 1, and
set_binning_vertical 1. To disable binning, use the command
set_binning_horizontal 0, and set_binning_vertical 0. Horizontal (2x1) and
vertical (1x2) binning can also be used independently.
C11 Generating Test Patterns
The camera can generate a test pattern to aid in system debugging. Use the command
set_video_mode 2 to activate the test pattern. The test pattern is a ramp from 0 to
255DN, then starts at 0 again. Use the test pattern to verify the proper timing and
connections between the camera and the frame grabber.
End-of-line Sequence
To further aid debugging, the camera can generate an end-of-line sequence. The end-of-
line-sequence outputs "aa", "55", "line counter", "line average", "pixels above threshold",
"pixels below threshold". To activate the end-of-line sequence, use the command
endof_line_sequence 1. To disable the end-of-line sequence, use the command
endof_line_sequence 0.
Use the
set_upper_threshold and set_lower_threshold commands to set
threshold values between 0 and 255.
C12 Returning Video Information
The camera’s microcontroller has the ability to read V
input
. This functionality can be used
to verify camera operation and to perform basic testing without having to connect the
camera to a frame grabber.
