Gain
The ON Semiconductor MT9P031 sensor provides analog gain for the following
increments only:
•
2.5 dB
•
3.2 dB
•
5.0 dB
•
14.9 dB
You can set gain for the Mako U-503B camera in 0.1 dB increments. To set
increments in-between the analog increments listed above, the digital gain is used.
In this case, image brightness is not transferred into fully proportional gray levels.
Displayed in a histogram, the camera image signal shows this effect: while the
curve for the image with analog gain is continuous, the curve for the image with
digital gain is discontinuous.
Reconfiguration delay
Generally, some parameters can be changed during exposure without affecting the
timing. Changing the following parameters during exposure leads to a delay:
• BlackLevel
• ExposureTime
• Gain
• OffsetX
• OffsetY
When any of these parameters is entered, the next frame starts only after readout
and sensor reconfiguration delay are finished. The reconfiguration delay is typically
0 to 1200 µs, depending on the individual parameters change. Please, consider this
delay for your application.
