Choose among the following video capture modes.
|
|
Single
|
|
Lets you capture a single video frame as an image.
|
|
Average
|
|
Lets you capture a single image as a result of accumulating and averaging several video frames. This mode is usually used for the noise reduction.
|
|
Integrate
|
|
Lets you capture a single image as a result of accumulating and integrating several video frames. This mode is usually used to boost intensity values under low-light conditions.
|
|
Sequence
|
|
Lets you capture several video frames as an image sequence. See Sequences for more details.
|
|
Sequence average
|
|
Lets perform a sequential frame averaging and capture several averaged frames as an image sequence. . See Sequences for more details.
|
|
|
Displays the number of the workspace frame into which the acquired image or sequence will be placed. By default, ImageWarp will set this number to the first available value. Type or select another value if you want the output image to be placed into a different frame.
|
|
Note ImageWarp's frames are the numbered windows in which the images and sequences reside, and they should not be confused with the frames of the video stream.
|
|
|
Displays the amount of video frames to be captured into the sequence or used for averaging. Type or select another value if you want to change the number of video frames to be captured.
|
|
Note selecting a large number of frames in the Sequence mode can lead to the memory overload. To avoid it, ImageWarp sets the limit to the maximum number of frames based on the amount of RAM available in the system.
|
|
|
Displays the delay (in milliseconds) between consecutive video frames to be captured into a sequence or used for image averaging/integration. Type or select the desired interval between frames. If the video device frame rate exceeds the selected delay time, ImageWarp will use the fastest frame rate possible for the current video device adjusting the actual delay time accordingly.
|
|
|
Displays the number of consecutive frames used for the sequential averaging or integration. For better performance this parameter must be a power of 2.
|
|
|
Select this option in the Integrate mode to activate the software auto-exposure. ImageWarp does it by automatically re-adjusting the number of consecutive frames being integrated to produce the "best-fit" image.
|
|
|
Check this box to have ImageWarp display a minimized live video in the preview window of the dialog box. During the capture process, live preview is automatically synchronized with the ongoing frame rate.
|
|
|
Check this box to have ImageWarp display a full size image resulting from executing the current acquisition function in real time. The number of the image frame in which the output preview is displayed can be selected in the corresponding box.
|
|
Note it is not recommended that the live previews of the capture dialog be enabled while the Video Window is displayed because it can disturb the video stream and lower the frame rate.
|
|
|
Click this button to start capturing. The progress indicator on the status bar will display the capture progress for the Average and Sequence modes.
|
|
Note you can cancel capturing by pressing the PAUSE/BREAK key at any time during the capture process.
