What does the term "pixels" refer to in digital imaging?

In digital imaging, the term "pixels" refers to the smallest unit of a digital image or display. Each pixel represents a single point in the image and contains information about color and brightness. The reason "millions of light receptors" is an appropriate description is that each pixel can be viewed as a small receptor that captures light and color information, contributing to the overall image quality.

While pixels do contribute to how light is represented in digital formats, they are not electronic components, color filters, or signals. Instead, they are fundamental building blocks that, when combined in a grid or array, create the visuals we see on screens. This collective representation of pixels allows for the detailed and diverse imagery found in modern digital imaging technologies.
