Application notes UI-388x/UI-588x

Sensor, pixel clock

•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 range changes depending on whether the sensor is operated in 8/10 bit or 12 bit mode.

•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 is 28 pixels which is caused by the sensor.

Frame rate

•The sensor will not get faster in 8-bit mode than in 10-bit mode.

Binning

•The sensor does not support binning.

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.

•For fast consecutive trigger signals (overlap trigger mode), the flash should be set to "Constant high" to avoid brightness differences in the image.

White balance

•The white level may not be reached for very long exposure times and minimum gain. Increase the gain by one level if necessary. Increase the gain boost or the master gain by one level if necessary.

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

•Subsampling does not increase the frame rate.

•The pixel clock range 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.

uEye LE USB 3.1 Gen 1

•The camera does not support subsampling.

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

•The camera has no internal image memory.
