Camera Setup
CMOS Image Sensor
Configures the operation of the CMOS image
sensor. Typically these parameters will be
obtained during the calibration process, and
do not need to be modified directly by the user.
Note that the Quadrus EZ has one of two
types of image sensors, CCD or CMOS. Even
though some of the parameters between the
sensors are similar, they are configured independently with different configuration commands.
Therefore, the user needs to know which sensor type is installed in the Quadrus EZ. To
find the sensor type, send
<op,10> . The reader will reply with a status report that includes
the message: “SENSOR=CCD” or “SENSOR=CMOS.”
Shutter Speed (CMOS)
Gain (CMOS)
Usage:
Faster shutter speeds reduce blurring in faster applications.
Slower shutter speeds are useful in slower and lower contrast applications.
Definition:
Shutter speed is the time, in fractions of a second, that the CMOS sensor is
exposed to light. For very short shutter times, additional external lighting
may be required.
Serial Cmd: < K541,shutter speed ,gain,contrast,offset>
Default: 250 (1/250 second)
Options: 50 to 50,000
Usage: Can be used to adjust pixel gray scale values for readability.
Definition:
Controls the amount of energy applied to the pixel gray scale values, prior
to output. This value can vary depending on lighting conditions and shutter
speed.
Serial Cmd: < K541, shutter speed, gain ,contrast,offset>
Default: 10
Options: 0 to 63
