Resolution Testing is a method used to evaluate the clarity and detail of images or displays. It measures how well a system can reproduce fine details, often expressed in terms of pixels or lines per inch. This testing is crucial in fields like photography, television, and computer graphics, where high-quality visuals are essential. During Resolution Testing, various patterns or images are displayed to determine the maximum level of detail that can be perceived. The results help manufacturers and consumers understand the performance of devices such as monitors, cameras, and projectors, ensuring they meet specific quality standards.
