Answer:
1) 2 bits 2) shown in explanation 3) shown in explanation 4) 22 bits per pixel (2.75 bytes)
Explanation:
As a bit is one of two states, 1 or 0, 2 bits is sufficient to represent 4 colors:
00 = color 1
01 = color 2,
10 = color 3,
11 = color 4
This would be the custom type of encoding for that specific image as it only uses 4 colors.
Now to calculate the amount of memory saved, which is quite simple:
24-2=22
So you Would save 22 bits per pixel or 2.75 bytes per pixel.
RGB is a colour complementary wherein the main light colors of red, green, and blue are coupled in distinct ways of representing a range of colors. It uses to design is named again for preliminary colors red, blue and green of 3 primary additive color schemes.
Following are the solution to the given question:
[tex]\bold{= \log_2\ \text{(total number of colors)}}\\\\\bold{= \log_2\ (4)}\\\\\bold{= 2}[/tex]
[tex]\to \bold{ Black = 00}\\\\\to \bold{White= 01}\\\\\to \bold{Red= 10}\\\\\to \bold{Blue= 11}\\[/tex]
[tex]\to \bold{= (17 \times 20) \times 24} \ \bold{= 8160}[/tex]
The number of total bits for the picture now is custom encoded
[tex]\to \bold{= (17 \times 20) \times 2} \ \bold{= 680}[/tex]
Calculating the percentage:
[tex]\bold{= \frac{\text{(original bits - new bits)} \times 100}{\text{original bits}}}\\\\\bold{= \frac{(8160 - 680) \times 100}{8160}}\\\\\bold{= \frac{7480 \times 100}{8160}}\\\\\bold{= \frac{748000}{8160}}\\\\\bold{= 91.67\%}[/tex]
So, the final answer is "2,00,01,10,11, and 91.67%"
