When the digital image matrix size increases, what happens to the size of the individual pixels?

Explanation:
Pixel size decreases because the same image area is being divided into more samples. Pixel size is determined by the field of view divided by the matrix size; keeping the field of view constant while increasing the matrix size means each pixel covers a smaller area, so the pixels become smaller. This higher sampling density can improve spatial resolution, though it may affect noise and data requirements.
