3. The SeaWiFS mission is described as having a camera that takes images in 8 IR bands (or channels) with a photometric digitization of10 bits (210 brightness levels).   Given a constant data rate of 665 kbps (103 bits per second) and assuming there is onboard processingthat converts the 1-D swaths into image frames of size 304 x 274 pixels, how many seconds will it take to download one of those image

Solution

The datarate per second is given as by the formula\'

datarate per second =frame size *frame rate

the datarate =103bits/sec and frame size=304*274 pixels we have to calculate the time to download or display the image. which is called as frame rate.

(frame size =304*274*1=83296) bytes it is gray scale image so it is using only 8IR bands(1 byte per pixel).

83296/1024*1024= 83296/1048576=0.07942MB=1MB

now frame rate =datarate per second/frame size

=103/8388608bits

0.0000122785secs.
