ANIMATED PROGRAM IMAGE EFFECT PRODUCTION GUIDELINES |
Television Tokyo has prepared the following production guidelines in the interest of minimizing the risks of viewer exposure to harmful stimuli. The production and broadcasting of animation conducted on the basis of a firm awareness of these guidelines will eliminate almost all risks emerging from such programs. 1. Avoid use of more than one light flash per each one-third second(8 frames for film, 10 frames for television). 2. Because sudden cut changes or swift image changes will also cause
the same impact as light flashes, avoid their use in excess of one
such change per each one-third second. 3. Flashes and cut changes using the color "isolated red" will also be dangerous. However, there are no problems with color combinations which exclude isolated red when the luminance (brightness) is at the same level. 4. As a general rule, it is desirable to avoid use of systematic patterns (strips, bars, spirals, dart boards, etc.) with varying luminance levels. Patterns which reverse are the most provocative, but those which drift are not provocative. According to Professor Harding or the U.K., an accepted authority on research into spasms caused by light hypersensitivity; "As long as the television itself is used as a medium to send out images via light changes, it will be impossible to totally eliminate the risk of symptoms occurring as a result of light stimulation." �@ |
