Question
used to represent each RGB component (8 for R, 8 for G, 8 for B)? What is the color depth of an image using this RGB configuration? 3. Create an image of your own in Excel, similar to smiley Your grid should be 15 x 15. (What is the image resolution for this?) Your image should use 6 different colors. What is the smallest color depth that is needed to accommodate 6 different colors? Calculate the storage size required for your image, assuming a bitmap scheme that uses a 32-bit representation of colors. Provide an answer in bits and an answer in bytes a. b. c. 17 escExplanation / Answer
3.
a. The image resolutionis the total number of pixels in the image = 15 x 15 = 225 pixels
b. For 6 colors we will require 3-bit color depth. Because with 2-bits there are only 4 represenatinos:00, 01, 10, 11. Whereas with 3-bits, we can represent 8 colors:000, 001, 010, 011, 100, 101, 110, 111.
c. In bits : file size = number of pixels * size of 1 pixel = (15 x 15) x 32 bits = 7200 bits
In bytes : 1 Byte = 8 bits. Therefore, file size = 7200 / 8 Bytes = 900 Bytes
