Camcorder jamming techniques using high frame rate displays

A method for distorting a recording of a plurality of frames comprising the step of imposing, using a processor, a variable frame period modulation in a digital domain on a digital representation of the plurality of frames at a frequency that is above a critical fusion frequency of the human visual system, imposing a brightness modulation having an odd-number of half cycles of variation over an integration period of the recording and outputting, by the processor, a modulated digital representation of the plurality of frames to a high frame rate tonal display.

A method for distorting a recording of a plurality of frames comprising the steps of:

• imposing, by a processor, a modulation in a digital domain on the digital representation of the plurality of frames at a frequency that is above the critical fusion frequency of the human visual system;
• and
• imposing, using the processor in a digital domain, one of a 1-dimensional and 2-dimensional taper or gating function to each of a digital representation of the plurality of frames and moving the taper or gating function in one of an x-dimension, y-dimension, and x and y dimension so that the modulation completes at least one cycle during a predetermined period of time corresponding to a rate that is above a critical fusion frequency of the human visual system to produce a pseudo-rastering effect in the recording, and outputting, by the processor, a modulated digital representation of the plurality of frames to a high frame rate tonal display.

A projection system for distorting a recording of a plurality of frames, comprising a processor for imposing a modulation in a digital domain on a digital representation of the plurality of frames at a frequency that is above a critical fusion frequency of the human visual system;

• and imposing a simulated shuttering of the digital representation of the plurality of frames, the simulated shutter having an on-time, a shutter width (off-time) and a shutter spacing (time from one on-time to the next on-time), wherein the modulation is one of shutter width relative to shutter spacing, brightness, frame period, and pseudo-rastering, said processor outputting a modulated digital representation of the plurality of frames to a high frame rate tonal display.
