Vision is a continuous process with the blink breaking the sequence. Science has shown us that the average shutter speed for human is somewhere around 1/50th of a second.
techno-horror is a subgenre of horror fiction where the major source of horror is modern technology. it focuses on how technology can be a force of evil, either in its own right or as pawns of mad scientists/engineers. another form of techno-horror is the inclusion of technology into otherwise classical horror narratives. an example is the evolving j-horror genre: classical "scares", such as ghosts, spirits, curses, etc., propagate via hi-tech media: computer networks, cell phones, etc. here, modern technology is not a threat per se, but rather a new conduit for various dark forces. the subgenre is notably most popular in the western world and japan, with little prominence elsewhere in the world.
