Question

How does sampling gets accomplished with a sensing strip being used for image acquisition?

(a) The number of sensors in the strip establishes the sampling limitations in one image direction and Mechanical motion in the other direction

(b) The number of sensors in the sensing array establishes the limits of sampling in both directions

(c) The number of mechanical increments when the sensor is activated to collect data

(d) None of the mentioned

This question was posed to me in an interview for internship.

The doubt is from Basics Of Image Sampling & Quantization in portion Digital Image Fundamentals of Digital Image Processing

Answer 1

Right answer is (a) The number of sensors in the strip establishes the sampling limitations in one image direction and Mechanical motion in the other direction

The best I can explain: When a sensing strip is used the number of sensors in the strip defines the sampling limitations in one direction and mechanical motion in the other direction.
