What happens to the size of individual pixels when the matrix size decreases?

• A. Increases
• B. Decreases
• C. Remains the same
• D. Reduces

Answer: (A)

Pixel size is determined by how much physical area one pixel covers on the display. If you keep the overall image area fixed and reduce the number of pixels across that area (a smaller matrix), each remaining pixel has to cover more space. In other words, fewer samples fit into the same size, so the pixel pitch grows and the individual pixel size increases. A simple way to picture it: shrink the grid from many tiny squares to fewer larger squares on the same page, and each square becomes bigger.
