What does pixel pitch primarily determine about an image?

Pixel pitch primarily determines the sharpness of an image because it refers to the distance between the centers of adjacent pixels. A smaller pixel pitch indicates that pixels are closer together, which typically results in a higher resolution and greater detail in the image. This higher resolution allows for more information to be represented in the same physical area and, consequently, enhances the clarity and sharpness of the image displayed.

Sharpness is a crucial aspect of image quality as it influences how well-defined the details are. When the space between pixels is minimized, the eye perceives a crisper, more focused image. In contrast, larger pixel pitches can lead to images that may appear more pixelated or blurry, as there are fewer pixels to convey detail effectively. Thus, pixel pitch directly impacts the sharpness of the displayed image.
