The best component in a digital system will determine the resolution in a digital image.

• A. True
• B. False
• C. It depends on software
• D. It depends on processing

Answer: (B)

Resolution comes from the entire imaging chain, not just the best component. The detail you can capture in a digital image is limited by the component with the weakest resolving power—typically the sensor's pixel count and the lens's ability to resolve fine detail. Even if you have a superb sensor, a mediocre or poorly matching lens won’t deliver higher true resolution, and a great lens cannot exceed what the sensor samples. Processing or software can sharpen or interpolate to make details appear crisper, but that doesn’t create real information beyond what the sensor and optics captured. So the idea that the best component alone determines resolution is not correct.
