If you are still using the same camera you were before, then you cannot get 16 bit grayscale images from it: it is limited to 12 bit grayscale. That is not a "restriction of implementation": the Aptina MT9J003 CMOS image sensor used in the camera is only 12 bit.
If your thought is that somehow you should be able to convert 12 bits per R, G, B channel into 16 bits total of grayscale, then No, that is not possible.

Thanks for your reply sir . I am still using or trying to interface the same 12bit grayscale camera. I thought of atleast acquiring image i 16bit and then getting it to 12bit later ???
Can you help me in this case ??To acquire a12 bit image in MATLAB?

There is no chance of acquiring a 16 bit per channel image with the camera you are using: the sensor hardware is only 12 bit.
The question about acquiring a 12 bit image from your camera should go back to your previous (and still active) question, http://www.mathworks.com/matlabcentral/answers/35853-12bit-grayscale-image-acquistion
