如果该字段设置为 UNCALIBRATED,则相机系统无法进行可重复对焦,因此除了 0 为无限远和MINIMUM_FOCUS_DISTANCE为可以设置的最近焦距之外,设置没有合理准确的物理值。它可能仍然以屈光度为单位,但根本不是非常准确的。
从安卓设备获取LENS_FOCUS_DISTANCE可以通过使用Camera API或Camera2 API来实现。这两个API提供了访问相机硬件功能的接口。 使用Camera API: LENS_FOCUS_DISTANCE是相机参数之一,表示相机的焦距。可以通过以下步骤获取LENS_FOCUS_DISTANCE: 获取相机实例:使用Camera.open()方法获取相机实例。 获取相机参数:使用Camera.getPa...
The invention discloses an imaging lens with a variable focus distance. The imaging lens with the variable focus distance comprises a first lens group with negative refracting power, a second lens group with positive refracting power, and a third lens group with positive refracting power from ...
在安卓摄像头api2中,我们可以设置LENS_FOCUS_DISTANCE (从0到10)。我的问题是如何获得LENS_FOCUS_DISTANCE?例如,在自动对焦之后,我想知道当前的对焦距离。我应该调用哪个函数?谢谢。 11K0票数2 EN android android-camera2 autofocus 回答1 Stack Overflow用户 发布于 2018-01-18 10:48:41 您需要创建一个Camera...
While kit lenses may not offer true macro magnifications, don’t underestimate their close-focusing capabilities. Often, you can get a lot closer to your subjects than you might think! I encourage you to take a moment and test out your kit lens’s minimum focusing distance. You might be ...
