Camera Example

To run the example from http://, open the Welcome mode and select the example from Examples. For more information, visit http://.

A Camera class is created that will act as our Camera. It has a user interface, control functions, setting values and a means of defining the location where the image or video clip is to be saved. It will also store the image and video settings.

The Camera class contains an instance of https://, the API class interface to the hardware. It also has an instance of https:// to take still images and an instance of https:// to record video. It also contains the user interface object.

The Camera constructor does some basic initialization. The camera object is set to '0', the user interface is initialized and UI signal are connected to slots that react to the triggering event. However, most of the work is done when the setCamera() function is called, passing in a https://.

setCamera() sets up various connections between the user interface and the functionality of the Camera class using signals and slots. It also instantiates and initializes the https://, https:// and https:// objects mentioned above. The still and video recording visual tabs are enabled and finally the https://() function of the https:// object is called.

Now that the camera is ready for user commands it waits for a suitable event. Such an event will be the key press of either the https:// or https:// buttons on the application window. Camera focus will simply display the viewfinder and lock the camera settings. Key_Camera will either call takeImage() if the https://() is https://, or if the capture mode is for video then one of two actions will occur. If the recording state shows that we are currently recording then the stop() function is called resulting in a call to https://(), whereas if we are not recording then a video recording is started with a call to https://().
