What is another term for size distortion?

• A. Distortion
• B. Blur
• C. Compression
• D. Magnification

Answer: (D)

Size distortion is about how large or small an image appears compared with the actual object. The term used to describe that change is magnification. Magnification is the ratio of the image size to the object size, so if the image is bigger, magnification is greater than 1; if smaller, it’s less than 1 (often called minification). This focuses exactly on the change in size caused by the optical system. Other terms like blur refer to sharpness, distortion more often to shape or geometric errors, and compression to reducing data size, so they don’t capture the idea of the image’s size relative to the object as cleanly.
