One image can capture within 0.045 seconds and we consider this as a rate as 0.045 seconds per image or maybe 200/9 images per second. It is much convenient to say for the rate always is controlled by the time, and the unit of our choice is image per second. The formula of our rate is expressed as r = i/t where r = rate, i = number of captured images, t = time For 3 seconds, the images has about i = rt = (200/9)(3) = 66.67
