is_SetSubSampling
Syntax
INT is_SetSubSampling (HIDS hCam, INT mode)
Description
Using is_SetSubSampling(), you can enable sub-sampling mode both in horizontal and in vertical
directions. This allows you to reduce the image size in the sub-sampling direction without scaling
down the area of interest. In order to simultaneously enable horizontal and vertical sub-sampling, the
horizontal and vertical sub-sampling parameters can by linked by a logical OR.
Some monochrome sensors are limited by their design to mere colour sub-sampling. In case of fine
image structures, this can result in slight artifacts.
The adjustable sub-sampling factors of each sensor are listed in Specifications: Sensors chapter.
Some sensors allow a higher pixel clock setting if binning or subsampling has been activated. If
you set a higher pixel clock and then reduce the binning/subsampling factors again, the driver will
automatically select the highest possible pixel clock for the new settings.
Changes to the image geometry or pixel clock affect the value ranges of the frame rate and
exposure time. After executing is_SetBinning(), calling the following functions is recommended in
order to keep the defined camera settings:
is_SetFrameRate()
is_SetExposureTime()
If you are using the DCU camera's flash function: is_SetFlashStrobe()
