How is spatial resolution defined?

A. How distinct each pixel is from its neighbor
B. How the illusion of nearness is created
C. How the illusion of distance is created
D. How 3D images are made visible

Answer :

Spatial resolution is defined as how distinct each pixel is from its neighbor. The correct answer is option A.

Spatial resolution refers to the ability of an imaging system to distinguish small details and objects in an image. It is a measure of how well the system can differentiate between closely spaced pixels, which determines the level of detail and clarity in the image.

  • Pixel Distinction: High spatial resolution means that each pixel can be clearly distinguished from its neighboring pixels, resulting in a sharper and more detailed image.
  • Image Clarity: The greater the spatial resolution, the finer the details that can be resolved in the image.

The other options do not accurately describe spatial resolution:

  • Illusion of Nearness: Refers to techniques used in art and imaging to create a sense of closeness, not related to pixel distinction.
  • Illusion of Distance: Similar to the illusion of nearness but refers to creating a sense of depth, not related to pixel distinction.
  • 3D Images: Involves techniques to render three-dimensional images, which is a different concept from spatial resolution.

Therefore, spatial resolution is defined as how distinct each pixel is from its neighbor.
