Read the function information at more closely.
Hint: Use a 1 x 1 block and a border of [1 1]
Hint: Use TrimBorder false

blockproc normally moves in "jumps" of the block size when it scans the image. However it can move with an overlap, so that it would move over by just one pixel if you want. I attach demos for both ways.
However I think that if you want to move over just one pixel at a time, then the function you should probably use instead would be nlfilter(). You can have a custom filter where you did a median with the median() function. Demo attached for that also.
