9. You implement a photo ticketing system to take digital pictures of vehicles when they run red lights. You install one camera at 13th and Main Street. When a vehicle passes through a red light a sensor triggers the camera to take a picture. The picture is 400 pixels high by 600 pixels wide. The image is grayscale, with the shade of each pixel defined by 16 bits. a. How many bits is a single picture? b. If you receive 300 pictures a month, how much storage will you need to hold three years of these pictures (assuming no growth)? c. You decide you want to convert from still to motion video. You plan on taking 10 seconds of video at 30 pictures per second. How many bits would a single video clip be?
