Embodiment two:
Be illustrated with the mobile phone of Android platform, and refer to Fig. 4:
The dispatchTouchEvent that this product adopts Android to carry (distribute by touch event, the touch screen event-handling method that android system carries) carry out touch screen case distribution and process, the position of the coordinate of touch area with focus before frame and light-metering frame is compared, to judge that this time dragging or click event are the operations carried out for focusing or light-metering.Utilize calculateTapArea (coordinates computed region, calculates rectangular area centered by contact) method to carry out coordinate transform after judging and be converted into the utilizable driving coordinate of bottom by the screen coordinate of UI.By high pass interface setMeteringArea, (photometry region is set, interface for photometry region is transmitted to bottom) carry out the setting of photometry region, by JNI supplemental characteristic be delivered to HAL layer and finally received by bottom, proposed by the invention comprises following three modules by focusing and the independent method of carrying out finding a view of light-metering point:
(1) acquisition of focusing area and photometry region touch screen event and region decision: 1. .WindowManagerService (window management service, for the service of View in management window in Android ccf layer) distribute Touch event to current top Activity, function dispatchPointer (distribution contact in WindowManagerService, the method of message is sent) in WindowManagerService, by the client proxy object of an IWindow, message is sent to corresponding IWindow service end, a namely IWindow.Stub subclass, 2.. the implementation method dispatchPointer of IWindow.Stub subclass can be called after receiving message, 3.. the dispatchTouchEvent method of this View can be called after being delivered to the View of top layer, so far completed the acquisition of touch screen event.The touch screen coordinate figure of current acquisition and focusing area coordinate figure before and photometry region coordinate figure are compared and judges to draw that current click or drag area are as effective coverage or light-metering effective coverage or the inactive area of focusing.
(2) calculating of effective coverage coordinate and UI are to the coordinate transform driven:
Focusing area and photometry region is calculated according to current contact by calculateTapArea, (coordinate transform is prepared afterwards by the prepareMatrix in mapRect and the Util tool-class in Matrix, AndroidApp layer tool-class, for being bottom layer driving coordinate by upper interface Coordinate Conversion) upper interface Coordinate Conversion is bottom layer driving coordinate by coordinate transform
(3) Parameter transfer and physical layer interface call
After respective regions has been calculated, by setMeteringArea and setFocusArea of framework layer, (focusing area is set, interface for focusing area is transmitted to bottom) parameter is passed to JNI (Java Native Interface, JAVA calls this locality, for completing upper strata java language calling to bottom c language), and by an android_hardware_Camera (function of JNI layer, java language calling to c language in process camera model) be delivered to HAL layer, finally realized by native_set_parms.
Above-described embodiment, is only illustrate with Android platform, and is not limited to Android platform, at the iOS of Apple, the platforms such as the Windows of Microsoft or operating system can also realize.
According to the embodiment of the present invention, when user adopts the present invention to carry out preview composition, focusing area and photometry region are selected in the operation that can oppose as required, carry out composition, improve Consumer's Experience according to different scene.
Above with reference to the accompanying drawings of the preferred embodiments of the present invention, not thereby limit to interest field of the present invention.Those skilled in the art do not depart from the scope and spirit of the present invention, and multiple flexible program can be had to realize the present invention, and the feature such as an embodiment can be used for another embodiment and obtains another embodiment.All use do within technical conceive of the present invention any amendment, equivalently replace and improve, all should within interest field of the present invention.
