# CAMERA_SetVsyncCallback

## Syntax

  `#include <twl/camera.h>`
  `void CAMERA_SetVsyncCallback(CAMERAIntrCallback callback);`

## Arguments

callback | Callback function that is invoked during a camera VSync interrupt.

## Return Values

None.

## Description

Sets the callback function that is invoked during a camera VSync interrupt.
VSync interrupts will occur while a camera is active, even if it is not capturing images. As a result, note that VSync interrupts will occur even if the `CAMERA_IsBusy` function returns `FALSE` as long as the camera has been started by the `CAMERA_I2CActivate` function.
