Camera Performance and Features

It is desirable for camera performance to always use the maximum exposure time possible based

on the maximum line rate of the inspection system and any margin that may be required to

accommodate illumination degradation. However, it will be necessary to adjust the responsivity to

achieve the desired output from the camera. The camera has a gain feature that can be used to

make the necessary adjustment to the responsivity.

There are two gain adjustments available: color gains, which can be set independently for each

color (range 1 to 4x); and the system gain, which is applied to all colors (range 1 to 10x).

Image Response Uniformity & Flat Field Calibration

See the section Flat Field Category in Appendix A for GenICam features associated with this section

and how to use them

Related Features: Calibrate FPN, Calibrate PRNU, Calibration Algorithm, Calibration Target

It is common to find that an image has a lower response at the edges of the camera’s field of view

compared to its center. This is typically the result of a combination of lens vignetting (cos

4th

) roll-

off and the beam structure of the illumination source. Using a more diffused light may reduce the

roll-off effect. However, if decreasing the lens aperture improves the edge roll-off, then barrel

vignetting (a shadow cast on the sensor by the focus helical or extension tubes) may also be

present.

The camera can compensate for edge roll-off and other optical non-uniformities by using flat field

calibration.

•

When performing Flat Field (PRNU) calibration, the camera should be imaging a front

illuminated white target or rear bright field illumination source. The optical setup should be

as per the inspection system, including lens magnification, aperture, and illumination

intensity, spectral content, plus illuminator beam structure.

•

Flat field calibration should be performed when the camera temperature has stabilized.

•

When the camera is asked to run a flat field calibration it will adjust all pixels to have the

same value as that of the peak pixel value or target level, as per the calibration mode

selected.

•

If the flat field calibration is set to a target level that is lower than the peak value and the

system gain is set to a low value, then it is possible that the sensor will maximize its output

before the camera’s output reaches 255 DN. This can be seen when a portion of the output

stops increasing before reaching 255 DN with increasing illumination and the PRNU

deteriorates. This effect can be resolved by decreasing the light level or exposure control

time.

Following a flat field calibration, all pixels should be at their un-calibrated peak value or target

value. Changing gain values now allows the user to make refinements to the operating responsivity

level.

Note that the best flat field calibration can be achieved by performing it at the mid DN level of the

working range used in the operation. Any flat field error associated with residual non linearity in

the pixel will be halved as compared to performing a calibration at the peak value of the operating

range. A simple way of performing this is to reduce exposure time to half what is used in the

operation in order to get the mid DN level for flat field calibration. Once complete, return the

exposure time to its original setting.
