Camera.Area

public static class Camera.Area
extends Object

This class was deprecated in API level 21.
We recommend using the new android.hardware.camera2 API for new applications.

The Area class is used for choosing specific metering and focus areas for the camera to use when calculating auto-exposure, auto-white balance, and auto-focus.

To find out how many simultaneous areas a given camera supports, use getMaxNumMeteringAreas() and getMaxNumFocusAreas(). If metering or focusing area selection is unsupported, these methods will return 0.

Each Area consists of a rectangle specifying its bounds, and a weight that determines its importance. The bounds are relative to the camera's current field of view. The coordinates are mapped so that (-1000, -1000) is always the top-left corner of the current field of view, and (1000, 1000) is always the bottom-right corner of the current field of view. Setting Areas with bounds outside that range is not allowed. Areas with zero or negative width or height are not allowed.

The weight must range from 1 to 1000, and represents a weight for every pixel in the area. This means that a large metering area with the same weight as a smaller area will have more effect in the metering result. Metering areas can overlap and the driver will add the weights in the overlap region.

Summary

Inherited methods

From class java.lang.Object Object clone() Creates and returns a copy of this object. boolean equals(Object obj) Indicates whether some other object is "equal to" this one. void finalize() Called by the garbage collector on an object when garbage collection determines that there are no more references to the object. final Class<?> getClass() Returns the runtime class of this Object. int hashCode() Returns a hash code value for the object. final void notify() Wakes up a single thread that is waiting on this object's monitor. final void notifyAll() Wakes up all threads that are waiting on this object's monitor. String toString() Returns a string representation of the object. final void wait(long millis, int nanos) Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object, or some other thread interrupts the current thread, or a certain amount of real time has elapsed. final void wait(long millis) Causes the current thread to wait until either another thread invokes the notify() method or the notifyAll() method for this object, or a specified amount of time has elapsed. final void wait() Causes the current thread to wait until another thread invokes the notify() method or the notifyAll() method for this object.
