I checked by a program also, there is a intensity difference of around ~15 (8-bit images, intensity ranging from 0 to 255). By naked eye, one can quite easily observe this.

Well, I used a program to check the pixel intensities of the marked portions in (2) and (3). They were exactly same! However, these images are artificially created. If we use a camera to capture the two scene about which I am talking about, even in the images the shadow appears to get darker...

What I have understood after reading other answers as well: "less brighter objects surrounded by brighter area, appear darker and if the brightness of the brighter area increases further, then the less bright objects appear more dark." Am I right? The same thing also happens when we take photos...
