GX1660 User Manual |
Auto - The exposure time will vary continuously according to the scene illumination. The Auto exposure function operates according to the Auto and DSP controls
AutoOnce - The exposure will be set once according to the scene illumination and then remain at that setting even when the scene illumination changes. The AutoOnce exposure function operates according to the Auto and DSP controls
External - When ExposureMode is set to External the exposure time will be controlled by an external signal appearing on SyncIn1 or SyncIn2. In order for this feature to work, the parameter FrameStartTriggerMode must be set to SyncIn1 or SyncIn2. This feature is supported in version 1.36 firmware and above. It is not available on any of the
ExposureValue – In microseconds. The sensor integration time. 15000 corresponds to 15 ms integration time, 1000 corresponds to 1ms, etc.
Gain
Auto
This group of controls relates to the camera auto gain function.
NOTE: The camera must be acquiring images in order for the auto gain algorithm to update.
GainAutoAdjustDelay – Currently unimplemented.
GainAutoAdjustTol - In percent. A threshold. Sets a range in variation from GainAutoTarget in which the auto gain algorithm will not respond. Can be used to limit gain setting changes to only larger variations in scene lighting.
GainAutoMax – In dB. Sets the upper bound to the gain setting in Auto gain mode.
GainAutoMin – In dB. Sets the lower bound to the gain setting in Auto gain mode. Normally this number would be set to zero.
GainAutoOutliers - In percent. The percentage of image pixels that do not have to fit into the auto gain range
GainAutoRate - In percent. Determines the rate at which the auto gain function changes the gain setting.
GainAutoTarget - In percent. Controls the general lightness or darkness of the Auto gain feature. A percentage of the maximum GainValue.
GainMode
Manual - The camera gain is fixed by GainValue parameter.
Auto - The gain will vary continuously according to the scene illumination. The Auto gain function operates according to the Auto and DSP controls. Available on cameras with version 1.36 firmware and above.
AutoOnce - The gain will be set once according to the scene illumination and then remain at that setting even when the scene illumination changes. The AutoOnce gain function operates according to the Auto and DSP controls
GainValue – In dB. GdB = 20 log10(Vin/Vout). The gain setting applied to the sensor. Default gain is zero, and gives the best image quality. However, in low light situations, it may be necessary to increase the
gain setting.
