Question

pixel data assume your friend just sent you 32 bits of pixel data (just the 0s and 1s for black and white pixels) that were encoded after sampling an image. choose the two statements that are true. a. the digital image would be an exact copy of the original analog image. b. using fewer bits to represent an image usually results in a sharper, more detailed image. c. the 32 bits of pixel data are enough to produce a digital image, but the quality depends on how the original image was sampled. d. the fact that only 32 bits were used suggests that relatively large sample squares were used, which could cause the image to lose detail.

Explanation:

• Option A: A digital image (from sampled pixel data) can't be an exact copy of the original analog image as sampling involves approximation. So A is false.
• Option B: Using fewer bits to represent an image reduces the number of possible values (e.g., fewer shades), leading to less detail, not a sharper image. So B is false.
• Option C: 32 bits of pixel data (for black - white, each bit or group can represent pixels) can be used to produce a digital image. The quality of the digital image does depend on how the original analog image was sampled (like sampling rate, sample size), so C is true.
• Option D: If only 32 bits were used and large sample squares (fewer samples) were used, there would be less detail captured, causing the image to lose detail. So D is true.

Answer:

C. The 32 bits of pixel data are enough to produce a digital image, but the quality depends on how the original image was sampled.
D. The fact that only 32 bits were used suggests that relatively large sample squares were used, which could cause the image to lose detail.
