As we all know that the image file size depends upon the amount of information on the page and the colour content. It also depends on the resolution of the image, high resolution image took the more space to store the information comparing to the image using low resolution. The use of resolution depends upon the user.
a. The total size needed to store the images raw information having 800x600 with 24-bit color depth are shown as below:
File size= horizontal pixel * vertical pixel * bit depth/8*1024
i.e. file size= 800*600*24/8
=1440000 Bytes
For this byte the image should have the resolution of 150dpi.
b. CLUT is known as colour look-up table. The main function of this table is to transform a range of input colour into another range of colour. This could be either the hardware device which is built into an imaging system or the software function which is built into an image processing applications.a. 480768 bytes is the total size needed to store the image by using the clut encoding,
c. The ratio is 3:1.
