Android 中的真实相机
我正在使用 Android Camara 做一个颜色检测器，需要一个良好的参数配置来显示真实的颜色。例如，我聚焦在黑色衬衫上，但相机接受光线并将颜色更改为浅灰色，而我不想要它。 如果有人知道如何进行良好的配置，我将不胜感激。
I'm doing a color detector with the Android Camara and need a good parameters configuration that show me a realistic color. For example, I focus in a black shirt, but the camara take the light and change the color to light gray and i don't want it.
If someone knows how to make a good configuration I would appreciate it.

我不能说我自己做到了，但我认为您需要有一个活动，其唯一目的是进行校准。您将获得实时摄像头反馈，并提示用户按 + 或 - 如果衬衫是他们想要的黑色。 +/- 将增强应用于相机视图的颜色矩阵滤镜。拍摄照片并使用捕获的位图可能比实时摄像头输入更简单。
I can't say I have done it myself but I think you would need to have an Activity whose sole purpose would be to do calibration. You would be getting a live Camera feed and prompt the user to press + or - if the shirt is the black they want. The +/- would be augmenting a Color matrix filter applied to the camera view. It might be simpler to take a picture and work with the captured bitmap than it would be for the live camera feed.
