A Nokia Developer camera example application implemented using the Qt C++ Camera API, and exposed through a QML UI. The Camera Demo application allows users to set camera properties, show the view finder image and capture still images and video. The application also analyses the view finder image in real time and shows a histogram window about the image. The over-exposed areas are marked in the view finder to demonstrate the pixel manipulation techniques in real-time images.

Notes:

The ​Qt C++ Camera API used in this example provides relatively deep interaction with the camera when compared to the standard QML camera elements. If you want to develop a camera app in pure QML, see the ​QML Camera Example. The video feature is disabled on devices with 32 MB of graphics memory or less. The supported devices include Nokia 603, Nokia 700, Nokia 701 and Nokia 808 PureView. The first screenshot displays the basic camera view. In the second screenshot, the overexposed areas in the viewfinder image are indicated with red color. In the third screenshot, the settings of the still image mode are shown and in the last, the application is recording a video.
