A surveillance camera takes one picture every 4 seconds, has 5megapixel sensor
and 8bit ADC. You need to store all images taken during one week (24/7) on a 256GB memory card. Calculate the necessary compression ratio within 10% error.
Your answer: ______
_______
ANS> The total number of files taken in one week is
( )( )( )( )( Compression Ratio (CR) = ) /week (
( ) = ) Since one picture needs 5mega pixel with 8bit ADC, one picture will need
Thus,
The maximum data storage capacity with compression will be © 2013 Alexander Ganago
