The more pixels per inch:

The more pixels per inch:

• A. The better temporal resolution
• B. The better is the spatial
• C. The more shades of gray
• D. The higher the reliability

Answer: (B)

Increasing pixel density raises spatial resolution—the image’s ability to distinguish small, closely spaced structures. When more pixels fit into each inch, each pixel covers a smaller area, capturing finer spatial detail and producing crisper, more detailed images. Temporal resolution, on the other hand, is about how frequently frames are acquired over time and is not determined by pixel density. The number of shades of gray depends on bit depth, not how densely pixels sample the scene, and reliability relates to consistency, not image detail. So higher pixels per inch mainly enhances spatial resolution.
