Syntax
INT is_PixelClock(HIDS hCam, UINT nCommand, void* pParam, UINT cbSizeOfParam)
Description
The function returns the adjustable pixel clock range sets the piel clock. 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.
The pixel clock limit values can vary, depending on the camera model and operating mode. For detailed
information on the pixel clock range of a specific camera model, please refer to the Camera and sensor data
chapter.
The nCommand input parameter is used to select the function mode. The pParam input parameter depends on the
selected function mode. If you select functions for setting or returning a value, pParam contains a pointer to a
variable of the UINT type. The size of the memory area to which pParam refers is specified in the
cbSizeOfParam input parameter.
