Pixel Bit Depth and Shades of Gray Quiz

Digital imaging systems usually have bit depths of 2 to 8.

A pixel with a bit depth of 8 can produce 256 shades of gray. (correct)

Pixel bit depth refers to the number of pixels in an image.

The higher the bit depth, the fewer shades of gray a pixel can produce.

1 to 65,536 (correct)

1 to 256

1 to 1024

1 to 1,000,000

Pixel bit depth affects image resolution, not contrast.

Higher pixel bit depth results in higher image contrast resolution. (correct)

Lower pixel bit depth results in higher image contrast resolution.

Pixel bit depth has no effect on image contrast resolution.
