IDS Software Suite 4.96.1

Sensor, Pixeltakt

•If an image capture is running (is_CaptureVideo()) in freerun as well as in trigger mode, changes on the capturing parameters (such as exposure or gain) only have an effect on the image after the next which is caused by the sensor. If  no image capture is running (is_StopLiveVideo()) in trigger mode the capturing parameters can be set directly for the next image.

•The pixel clock can only be adjusted in steps. The steps get bigger with higher values.

•The adjustable pixel clock changes between 8/10 bit and 12 bit.

•Note the bandwidth requirements for bit depth greater than 8 bits per pixel.

•It is recommended to use packed color formats in 10 bit mode with high pixel clocks.

AOI

•The sensor speed does not increase by the use of a horizontal AOI.

•The minimum AOI height of 2 pixels is only supported in RAW format.

Subsampling

•Vertical subsampling increases the frame rate.

Trigger

•The internal sensor delay is about 2-3 lines when triggering. The line period depends on the selected pixel clock. The higher the pixel clock, the smaller the line period is.

•In overlapping trigger mode, the camera timestamp may be overwritten if the maximum exposure time is used. In this case, reduce the exposure time by approx. 1%.

Black level

•The sensor's automatic black level correction is always enabled.

White balance

•The white level may not be reached for very long exposure times and minimum gain. Increase the sensor source gain if necessary.

Sensor source gain

•For short exposure times (less than 10 ms), the sensor offers some more dynamic range. Here, you can set the analog sensor source gain to below 1.0x by using negative values. For this purpose, deactivate the analog gain boost if applicable and do not use the master gain. The result offers more dynamic and a better signal to noise ratio (SNR).

•The blacklevel increases for very long exposure times and /or high camera temperatures. If you correct the blacklevel using the blacklevel offset, the white balance may not be reached. In this case the pixel saturation is visible. To avoid this, the sensor source gain should be set to a small positive value.

•In combination with a master gain of 1.0x and deactivated gain boost, a low sensor source gain causes that the pixel saturation becomes visible. The result is a fixed pattern in bright image areas and additionally a vertical stripe pattern is visible. The full pixel saturation of 255 will not be reached at 8 bit mode.

IDS line scan ("AOI merge mode")

•For color sensors, the IDS line scan can only be used with at least 2 lines.

USB 3 uEye CP Rev. 2

•The value range of the pixel clock changes depending on whether the camera is operated with or without internal image memory.

•If the camera is operated without image memory there are additional pixel clocks in 10 MHz steps. The image quality may be reduced in the lower image area because of the slow reading-out. It is recommended to operate the camera with image memory in case of bandwidth problems or in multi-camera operation.

•Binning can also be used with color sensors. For color sensors, vertical binning can only be set together with horizontal binning. Horizontal binning can be set individually.

•On monochrome sensors, vertical binning increases the frame rate.

•Subsampling and binning cannot be used simultaneously.

•Hot pixel correction cannot be used when binning with a hardware color format is used (exception: RAW formats). Use adaptive hotpixel correction in this case.

uEye LE USB 3.1 Gen 1

•The camera does not support the IDS line scan mode ("vertical AOI merge mode").

•The camera has no internal image memory.

•Binning is only supported by monochrome sensors.

uEye SE USB 3.1 Gen 1

•Binning can also be used with color sensors. For color sensors, vertical binning can only be set together with horizontal binning. Horizontal binning can be set individually.

•On monochrome sensors, vertical binning increases the frame rate.

•Subsampling and binning cannot be used simultaneously.

•Hot pixel correction cannot be used when binning with a hardware color format is used (exception: RAW formats). Use adaptive hotpixel correction in this case.

USB 2.0 operation

•The camera model does not support USB 2.0 operation.

GigE uEye models

•The model does not support pre-trigger in memory mode, see Using the camera memory (GigE uEye cameras).

•Binning is only supported by monochrome sensors.
