What is the relationship between fill factor and spatial resolution?

• A. inversely proportional
• B. inversely proportional to the square
• C. directly proportional
• D. directly proportional to the square

Answer: (C)

Fill factor is the fraction of a pixel that is photosensitive, and spatial resolution is the ability to distinguish fine image details. When a larger portion of each pixel can respond to light, more accurate sampling of the scene is achieved and light from one point is less likely to blur into neighboring pixels. This helps preserve sharp transitions and improves the ability to resolve small details. In this simplified view, spatial resolution increases in proportion to fill factor, so the relationship is directly proportional. Keep in mind that actual resolution also depends on pixel size and the overall optical system; even a high fill factor can’t fully compensate for poor optics or very large pixels.
