Returns
None.
ResetTransferHardwareICMedia
This function stops a transfer that is either ready to run, or currently running. It also resets the system making it ready for the next call to InitCaptureICMedia.
void ResetTransferHardwareICMedia(
void
)
Returns
None.
SynchronizedPowerDownICMedia
This function puts the imager in power down mode upon receiving the next front edge of Vsync. The IC Media imager freezes when it goes into power down mode, so one of the checks after the power down is to make sure the Vsync is in the "between frames" state (in down time), since that’s where the IC Media camera should be frozen.
BOOL SynchronizedPowerDownICMedia()
Returns
UnBindPhysicalMemoryFromVirtualMemoryICMedia
This function unbinds the physical memory of an image, specified by "hPhysical," from the virtual memory location specified by "pVirtual." This does not, however, free any memory. The "pVirtual" pointer should still be a valid pointer pointing to RESERVED but not COMMITTED memory, and the physical memory should still be available for future bindings.
DWORD UnBindPhysicalMemoryFromVirtualMemoryICMedia(
DWORD hPhysical, void *pVirtual
)
Passed Arguments | Description |
DWORD hPhysical | A |
| returned by AllocatePhysicalScanSpaceICMedia when the space was allocated. |
void *pVirtual | A pointer to a virtual address. |
Returns
DWORD - This function returns
WaitForVsyncICMedia
This function waits until the imager sees the front edge of the Vsync, then it returns. Since many systems involve threads going to sleep waiting for this event to occur, a safety check on the way out of this function is to see if the Vsync reflects the camera being "between frames" (down time).
BOOL WaitForVsyncICMedia()
Returns
12 | IMAGETEAM™ 4X00 Series Hardware Interface Layer Specification |
