The number of pixels making up the digital image is described by which term?

• A. Pixel Depth
• B. Matrix Size
• C. Pixel Pitch
• D. Field of View

Answer: (B)

The number of pixels in a digital image is defined by the matrix size. This is the grid of pixels that makes up the image, described as width by height (for example, 1024 by 768). The total pixel count is obtained by multiplying those dimensions (1024 × 768 = 786,432 pixels). Pixel depth refers to how many bits store the color information per pixel, not how many pixels there are. Pixel pitch is the distance between adjacent pixels on a sensor or display, and field of view refers to how much of the scene is captured, influenced by sensor size and focal length. So the term that describes how many pixels comprise the image is matrix size.
