A color image with a size of 10 * 20 cm is scanned. The resolution of the scanner is 1200 * 1200 dpi

A color image with a size of 10 * 20 cm is scanned. The resolution of the scanner is 1200 * 1200 dpi, color depth is 16 bits. How much information will the resulting graphic file have?

We solve the problem:
1) 10 * 10cm 1200: 2.54 = 472 (dots / cm).
2) 1200 * 1200
4720 * 4720 = 22278400 – total points.
The color depth is 16 (Bit).
We multiply the color depth by the number of points, we get:
16 (Bit) * 22278400 = 356454400 (Bit)
356454400 (Bits) = approximately 42 (Megabytes)
Answer: The resulting graphic file will have a volume of 42 (Megabytes).
