What term describes the value for each pixel that encodes brightness and color?

• A. Pixel Value
• B. Pixel Size
• C. Pixel Density
• D. Color Depth

Answer: (A)

In a digital image, each pixel carries data that determines how bright it is and what color it shows. This per-pixel data is called the pixel value. For grayscale images, a single value represents brightness. For color images, that pixel value can be a set of channel values (like RGB) that together define the color at that location. The other terms describe different ideas: pixel size refers to the physical or sampling size of a pixel, pixel density to how many pixels fit in a given area, and color depth to how many distinct colors can be represented overall. The pixel value is the data that encodes brightness and color for that specific pixel.
