The space from the center of a pixel to the center of the adjacent pixel is called:

• A. Pixel Density
• B. Bit Depth
• C. Pixel Pitch
• D. Matrix Depth

Answer: (C)

Pixel pitch is the distance from the center of one pixel to the center of the adjacent pixel. This spacing determines how finely the image is sampled: a smaller pitch means more detector elements per area and thus higher spatial resolution, allowing you to resolve finer detail. Pixel density (pixels per unit length) is essentially the inverse of pitch—when pitch gets smaller, density goes up. Bit depth, on the other hand, is about how many gray levels a pixel can show, not how far apart pixels are. Matrix depth (or the size of the image matrix) refers to the number of pixels in the image array, not the physical spacing between pixels. So the center-to-center spacing is correctly described as pixel pitch.
