ans :D

I assume this question asks to map an M x N image to binary gray scale image.

  • We can think like we have to map MxN image (set of MN points) to binary space(2 points -0,1)
  • We know between set A (having a elements) and set B (having b elements), there are b a  distinct functions that can be formed.
  • In our problem, we can form 2 MN functions. 
  • each function will be distinct images

Hence 2 MN distinct binary images can be made

Images tend to be very large collection of data. The size of memory required for a 1024 by 1024 image in which the color of each pixel is represented by a n-bit number, (in an 8-bit machines) is n $\times$ 8 MB n/8 MB (1024 $\times$ 1024)/8 MB 1024 MB
