ImageCaptureFunction

ImageCaptureFunction

is an option for ImageCapture that specifies the function to apply to images acquired by the imaging device.

Details

  • Images are stored in the buffer after the function specified using ImageCaptureFunction is applied to them.
  • Typical settings include:
  • Identityno processing
    "LeftRightReverse"left-right mirroring
    "TopBottomReverse"top-bottom mirroring
    "Rotate90"counterclockwise 90° rotation
    "Rotate180"counterclockwise 180° rotation
    "Rotate270"counterclockwise 270° rotation
    fan arbitrary function f
  • Use ImagePreviewFunction to process images only during display.

Basic Examples  (1)

By default, ImageCapture stores the original captured image in the buffer:

Wolfram Language code: ImageCapture[]

Apply a function to the images after capture before storing in the buffer:

Wolfram Language code: ImageCapture[ImageCaptureFunction -> Binarize]

Properties & Relations  (1)

The function to be applied to all images at acquisition time is also a property of camera devices:

Wolfram Language code: dev = DeviceOpen[FindDevices["Camera"][[1]]]
Wolfram Language code: dev["Properties"]

By default, the capture function is Identity, which is equivalent to no processing:

Wolfram Language code: dev["ImageCaptureFunction"]

Specify a different capture function:

Wolfram Language code: dev["ImageCaptureFunction"] = ColorNegate;
Wolfram Language code: CurrentImage[ImagingDevice -> dev["DeviceName"]]
