Syntax

INT is_SetPixelClock (HIDS hCam, INT Clock)

Description

is_SetPixelClock() sets the frequency used to read out image data from the sensor (pixel clock frequency). Due to an excessive pixel clock for USB cameras, images may get lost during the transfer. If you change the pixel clock on-the-fly, the current image capturing process will be aborted.

Hinweis

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.

Achtung

Changes to the image geometry or pixel clock affect the value ranges of the frame rate and exposure time. After executing is_SetPixelClock(), calling the following functions is recommended in order to keep the defined camera settings:

If you are using the uEye's flash function: is_SetFlashStrobe()
