The term used to describe the amount of light emitted by pixels in a digital image is called?

The term used to describe the amount of light emitted by pixels in a digital image is known as brightness. Brightness refers specifically to the perceived intensity of light in an image and is a crucial factor in how an image is viewed on screens or printed. It is primarily influenced by the pixels' light output, directly affecting the visibility and detail of the image.

In digital imaging contexts, brightness can be adjusted to enhance or diminish the overall lightness or darkness of the image, thereby improving clarity and detail in different lighting conditions.

The other terms, while related to light and imaging, do not specifically define the emission of light by pixels. Exposure pertains more to the amount of light that reaches the imaging sensor during photography and can affect brightness but is not directly synonymous with it. Intensity generally refers to the strength of the light source but doesn't encapsulate the function of displaying light in pixels. Density is commonly used in film and radiography to describe the degree of blackening or opacity of an image and does not directly relate to light emission from pixels.
