pure virtual

Enumerates through the available video frame rates, based on the specified rate index, video frame format, size index and exposure mode.

Parameters

aRate	On return, the available video frame rates. Some rates may not be available due to, for example, current flash mode setting. In those cases a rate of 0 will be returned. Rates should be returned in order, highest first, so clients do not have to iterate through every one.

Returns: The currently set flash mode.

Note: if CCamera::New2L() or CCamera::NewDuplicate2L() is not used to create CCamera object, it is assumed that application is not prepared to receive extra added enum values (unrecognised). So, any extra enum value(unrecognised) (set in the ECAM implementation because of sharing clients) should not be returned from the ECAM implementation. To receive extra added enum values, application should rather use CCamera::New2L() or CCamera::NewDuplicate2L() to create camera object. ECAM implementation, after verifying this,(by checking version no.) may send new values, if set. In this case, application is assumed to be prepared to receive unrecognised enum values.

	)

static

Creates an object representing a camera.

@param  aObserver
        Reference to class derived from MCameraObserver designed to receive
        notification of asynchronous event completion.
@param  aCameraIndex
        Index from 0 to CamerasAvailable()-1 inclusive specifying the
        camera device to use.

Leave condition:  KErrNoMemory if out of memory.
Leave condition:  KErrNotSupported if aCameraIndex is out of range.
Leave condition:  KErrPermissionDenied if the application does not have
        the UserEnvironment capability.

@return Pointer to a fully constructed CCamera object. Ownership is passed
        to the caller.

            An application that creates a CCamera object must have
            the UserEnvironment capability.

@note   Applications using this method to create camera object may not receive enums/uids added in future(after being baselined).
        To receive them, they should rather use New2L() or NewDuplicate2L(), in which case, they should prepare
        themselves to receive unrecognised values.

API status: Required capability: UserEnvironment

Parameters

aObserver	Reference to class derived from MCameraObserver designed to receive notification of asynchronous event completion.
aCameraIndex	Index from 0 to CamerasAvailable()-1 inclusive specifying the camera device to use.

◆ PowerOff()

virtual void CCamera::PowerOff ( )

pure virtual

Synchronous function for switching off camera power.

◆ PowerOn()

virtual void CCamera::PowerOn ( )

◆ PrepareImageCaptureL() [1/2]

virtual void CCamera::PrepareImageCaptureL	(	TFormat	aImageFormat,
		TInt	aSizeIndex
	)

pure virtual

Performs setup and allocation of memory.

Called prior to calling CaptureImage() to keep the latency of that function to a minimum.

Needs to be called only once for multiple CaptureImage() calls. May leave with KErrNotSupported or KErrNoMemory or KErrInUse or KErrNotReady.

The specified image format must be one of the formats supported (see TCameraInfo::iImageFormatsSupported).

The specified size index must be in the range of 0 to TCameraInfo::iNumImageSizesSupported-1 inclusive.

Parameters

aImageFormat	The image format.

◆ WhiteBalance()

virtual TWhiteBalance CCamera::WhiteBalance ( ) const

pure virtual

Gets the currently set white balance adjustment value.

Returns: The currently set white balance adjustment value.

Note: if CCamera::New2L() or CCamera::NewDuplicate2L() is not used to create CCamera object, it is assumed that application is not prepared to receive extra added enum values (unrecognised). So, any extra enum value(unrecognised) (set in the ECAM implementation because of sharing clients) should not be returned from the ECAM implementation. To receive extra added enum values, application should rather use CCamera::New2L() or CCamera::NewDuplicate2L() to create camera object. ECAM implementation, after verifying this,(by checking version no.) may send new values, if set. In this case, application is assumed to be prepared to receive unrecognised enum values. Refer CCamera::CCameraAdvancedSettings::WhiteBalanceMode() implementation

◆ ZoomFactor()

virtual TInt CCamera::ZoomFactor ( ) const

pure virtual

Gets the currently set zoom factor.

Returns: The currently set zoom factor.
