Conversely, things become less sharp if they're moving. In fact, security cameras tend to have low frame rates (that might actually be for historical reasons – ...

In this case, images/frames are moving horizontally or vertically? Neither. They just appear; usually, they stand still for as long as a frame is displayed. But what is the minimum rate of frame/images so that still images appear as video? That depends on a lot of factors like brightness, amount of motion in the material, and mental state of the ...
