What does the term "resolution" refer to in the context of images?

In the context of images, the term "resolution" specifically refers to the clarity and detail of an image. It is typically measured in pixels, which denotes the width and height of an image (for example, 1920x1080 pixels). Higher resolution means more pixels, resulting in finer detail and sharper images, which is particularly important for print media and high-definition displays.

When an image has a high resolution, it can maintain its quality when scaled up or viewed close up, making it suitable for professional applications where visual fidelity is crucial. Conversely, images with low resolution may appear pixelated or blurry, reducing their effectiveness for detailed work.
