Detailed Description#

Warning

This section contains snippets that were automatically translated from C++ to Python and may contain errors.

QCamera can be used within a QMediaCaptureSession for video recording and image taking.

You can use QCameraDevice to list available cameras and choose which one to use.

cameras = QMediaDevices.videoInputs()
for cameraDevice in cameras:
    if cameraDevice.description() == "mycamera":
        camera = QCamera(cameraDevice)

On hardware that supports it, QCamera lets you adjust the focus and zoom. This also includes functionality such as a “Macro” mode for close up work (e.g. reading barcodes, or recognizing letters), or “touch to focus” - indicating an interesting area of the image for the hardware to attempt to focus on.

camera.setFocusPointMode(QCamera.FocusModeManual)
camera.setCustomFocusPoint(QPointF(0.25f, 0.75f)) # A point near the bottom left, 25% away from the corner, near that shiny vase

The minimumZoomFactor() and maximumZoomFactor() methods provide the range of supported zoom factors. The zoomTo() method allows changing the zoom factor.

camera.setZoomFactor(3.0)

After capturing the raw data for a camera frame, the camera hardware and software performs various image processing tasks to produce the final image. This includes compensating for ambient light color, reducing noise, as well as making some other adjustments to the image.

You can control many of these processing steps through the Camera properties. For example, you can set the white balance (or color temperature) used for processing images:

camera.setWhiteBalanceMode(QCamera.WhiteBalanceFluorescent)

For more information on image processing of camera frames, see Camera Image Processing .

See the camera overview for more information.

class PySide6.QtMultimedia.QCamera(position[, parent=None])#

PySide6.QtMultimedia.QCamera([parent=None])

PySide6.QtMultimedia.QCamera(cameraDevice[, parent=None])

Parameters:

position – Position
cameraDevice – PySide6.QtMultimedia.QCameraDevice
parent – PySide6.QtCore.QObject

Construct a QCamera which uses a hardware camera located a the specified position.

For example on a mobile phone it can be used to easily choose between front-facing and back-facing cameras.

If no camera is available at the specified position or if position is UnspecifiedPosition , the default camera is used.

Construct a QCamera with a parent.

Selects the default camera on the system if more than one camera is available.

Construct a QCamera from a camera description cameraDevice and parent.
