在 BlackBerry OS 6 中扫描但不拍照
我正在开发一个需要使用视频控制的项目。我的目标是打开相机并用它扫描一些单词。我不想拍它的照片。我需要在图像聚焦时自动捕获图像，而不是让用户通过按下按钮拍照。我现在想到的是，有一种状态是你的相机自动对焦，如果我能以某种方式捕捉到这种状态并拍摄快照，那么我就不必要求用户拍照。我不知道如何实现这一目标。有人可以帮我解释一下吗？
如果你们中的任何人使用过诸如条形码助手之类的条形码扫描仪或加拿大轮胎应用程序之类的东西，我想要类似的东西。
先感谢您！
I'm working on a project that requires me to use the video control. My goal is to turn the camera on and use it to scan some words. I don't want to take pictures out of it. I would need to capture the image automatically when the image is focused instead of having the users taking pictures by pressing the button. What I have in mind right now is there is a state where your camera auto-focuses, if I can somehow catch that state and take the snapshot, then I don't have to ask the user to take a picture. I have no idea how to achieve this. Can anyone shed some light on me please?
If any of you have used something like a barcode scanner like barcode assistant or the canadian tire app, I want something like that.
Thank you in advance!
