When we enlarge a low-resolution image of 262,144 pixels in a $512\times 512$ grid, pixilation occurs and the image gets blurry and unclear.

Work Step by Step

The number of pixels in a low resolution picture is less. Therefore, when a low-resolution image of 262,144 pixels is zoomed to a large extent, the pixels are stretched larger and larger in size. Thus, the image will become unclear and will consist of blurry, large, square boxes and stretched pixels will diminish the sharpness and clarity of the image.
