FLIR (point grey) MONO16 mode produce only 8bits image

Hi,

I use FLIR Blackfly BFLY-PGE-23S6C camera on Matlab2017b.

I open the camera on Mono16 mode. However, the image is limited to 8bit (256) values.

I used 2 methods to open and read an image:

The first is using videoinput:

vid = videoinput('gige', 1, 'Mono16');
src = getselectedsource(vid);
vid.FramesPerTrigger = 1;
img = getdata(vid);
im_16g_cropped=bitand(img,4095);
figure; imagesc(im_16g_cropped);

The second is using direct gigE:

camline=gigecamlist
g=gigecam(camline.IPAddress{1})

preview(g);
closePreview(g);

g.PixelFormat=g.AvailablePixelFormats{5}
g.AcquisitionFrameRateAuto='off'
g.AcquisitionFrameRate=5;
g.ExposureAuto='off'
g.ExposureTime=3e4
g.GainAuto='off'
g.Gain=29;

img=snapshot(g);
im_16g_cropped=bitand(img,4095);
figure; imagesc(im_16g_cropped);

Both methods produce the same result.

Anybodey has an idea?
