Digital Imaging Characteristics Chapter
2 Questions and Answers 100% Pass
What is spatial resolution in digital imaging?
✔✔ The ability of an imaging system to distinguish small details in an image.
How does pixel size affect image quality?
✔✔ Smaller pixels provide higher resolution and sharper details, while larger pixels reduce
image clarity.
What does contrast resolution determine in a digital image?
✔✔ The ability to differentiate between different shades of gray in an image.
Why is bit depth important in digital imaging?
✔✔ It determines the number of shades a pixel can display, affecting color and grayscale
accuracy.
What happens when an image has a low signal-to-noise ratio?
✔✔ The image appears grainy and lacks clarity due to excessive noise.
1
, How does dynamic range impact digital imaging?
✔✔ It defines the range of brightness levels a system can capture, affecting detail in highlights
and shadows.
What is the purpose of image sampling in digital imaging?
✔✔ It converts continuous visual information into discrete digital values for processing and
storage.
How does higher pixel density affect an image?
✔✔ It increases image sharpness and detail, improving overall resolution.
Why is modulation transfer function (MTF) important in digital imaging?
✔✔ It measures how well an imaging system preserves detail and contrast from the original
scene.
What role does exposure latitude play in digital imaging?
✔✔ It defines how much an image can be overexposed or underexposed while still retaining
usable details.
