Measure the points brightness of the image.

Is it possible to measure the brightness of the image - the camera preview?

I need a real-time measure several points on the screen or the whole screen
.
I used the class cameraExclass to see the live view.

I get an array of bits. What shows the individual bits in the array?

How many frames per second do you need to handle? You can use CameraEx.PreviewImageToJpeg, then create a Bitmap from the bytes array (InputStream.InitializeFromBytesArray with Bitmap.Initialize2) and use Bitmap.GetPixel to get the pixels colors.

May I ask You, how many frames I could get?

I would like to test this solution in lite paramedical uses so more is better for me.

You will need to test it. It depends on many factors including the device and preview size. I believe that at least a few images per second.
