What is the smallest resolvable piece of a scanned image called?

The smallest resolvable piece of a scanned image is known as a pixel. Pixels are the basic units of digital images, representing the smallest potential area of illumination, color, or intensity within an image. Each pixel holds information about its color and brightness, which together forms the complete picture when viewed as a cohesive whole.

In scanning or digital imaging, the resolution of an image is often described by its pixel dimensions, such as width by height in pixels. The concept of a pixel is fundamental in raster graphics and is essential for understanding how images are represented in digital formats. This makes it clear that the other terms do not accurately define the basic unit of a scanned image:

• "Cell" typically refers to a single unit of a grid, often in the context of databases or spreadsheets, and does not specifically apply to image resolution.

• "Node" is a term commonly used in network theory or within data structures to refer to a connection point or an endpoint in a diagram, which is not related to image resolution.

• "Vertex" is often used in geometry to denote a corner point of a shape, particularly in polygons, and it does not pertain to the smallest resolvable unit in scanned images.

Thus, considering the context of digital imaging
