Suppose a two-dimensional landscape image consists of 20,000 square pixels. If the size of each pixel were cut in half, _______ as many pixels would be needed to portray the same landscape. Such a decrease in the pixel size would represent a change in the _______ of the landscape.

Question

Quizplus · Accepted Answer

If each pixel's size is cut in half, the number of pixels needed would be four times as many because both the width and height of each pixel are halved, resulting in four times the number of pixels. This change affects the "grain" of the landscape, which refers to the level of detail or resolution.
