Determine the minimum amount of memory (in kilobytes) sufficient to store any 64 * 32 pixel bitmap image

Determine the minimum amount of memory (in kilobytes) sufficient to store any 64 * 32 pixel bitmap image, if you know that the image uses a palette of 16 colors. The palette itself does not need to be stored.

Let us determine what value the color depth will correspond to when it is precisely known from the condition of our problem that a palette of 16 colors was used in the image:

N = 2i;

16 = 2i;

2 ^ 4 = 2i;

i = 4.

Let’s determine what total number of pixels the image contains, when it is precisely known from the condition of our problem that its dimensions are 64 by 32 pixels:

64 * 32 = 2048.

Let’s find out the size of the image in bits:

2048 * 4 = 8192.

Let’s translate the volume found above into kilobytes:

8192: 8: 1024 = 1.

Answer: 1 KB.
