Question

select the correct answer.
which parameter determines the color depth of an image?
a. image size
b. pixel depth
c. pixel dimensions
d. resolution

Explanation:

To determine the parameter for image color depth, we analyze each option:

• Option A: Image size relates to the overall space an image occupies (e.g., in bytes), not color depth.
• Option B: Pixel depth (bits per pixel) directly determines how many colors a pixel can represent, thus defining color depth.
• Option C: Pixel dimensions (width × height in pixels) define the image's spatial size, not color depth.
• Option D: Resolution (e.g., pixels per inch) affects image clarity at a given size, not color depth.

Answer:

B. pixel depth
