The spatial resolution of the scan converter is determined by:

• A. Number of pixels in the scan converter matrix
• B. Number of bits per pixel
• C. The post-processing settings
• D. Brightness and contrast settings of the monitor

Answer: (A)

Spatial resolution hinges on how finely the image is sampled by the display grid. In a scan converter, the image is turned into a matrix of picture elements, or pixels, and the number of pixels across the image determines how small details can be represented. More pixels mean smaller sampling intervals and sharper detail, up to the system’s limits. The number of bits per pixel affects grayscale (contrast) resolution, not how finely the image is sampled. Post-processing can change perceived sharpness but doesn’t increase the actual sampling density. Brightness and contrast of the monitor influence appearance, not the underlying spatial sampling. So the number of pixels in the scan converter matrix best determines spatial resolution.
