here’s how (I believe) subliminal visuals are inserted into TV:
first a bit of review, for proof-of-concept; the human eye is built like this:
where light enters along the area inside the dotted lines. the backside of the eyeball’s inner wall----the sensing-area, like the CCD in a digital camera----uses “rod” & “cone” cells to detect light, there’s a blind-spot where the nerve attaches.
the cones are located toward the middle area, which corresponds directly to the center-spot of whatever you’re looking at, & detect color. the rods are toward the outer edges of the sensing-area & ‘see’ in black-&-white; they detect edges, differences, & motion, & ‘see’ mostly whatever’s going on in your peripheral vision. ever see a flashing light in your peripheral vision? those are your rod cells watching.
they are particularly drawn to these special kinds of shapes:
& I believe, though I cannot be sure, that some computer-drawn 3d imagery uses these to map out their special images (“Magic Eye”, perhaps? I dunno—but I’m 100% on the shape-recognition aspect)
these shapes will appear, I believe, in the following manner:
this uses the contrasting colors to add depth & shading to an image----look closely at paintings & you’ll see all kinds of odd color-use just like this. its also a great way to hide intentional patterns.
TV-visuals are based on certain common rules of art. one of those rules is the ‘rule of thirds’, which looks like this:
this rule shapes how & where images will appear on the screen. basically, interesting things will fall on the junctures of the lines, at the thirds-marks. i’ve labeled my favorite spot “D”; it is my favorite because that’s where most boobs will show up.
now the important part:
here’s my belief on how subliminal imagery is probably implemented in TV-broadcasts: some eye-catching thing will appear (most likely a boob, most likely in the d-spot) & a corresponding image made of L-shapes will simultaneously appear at the opposite corner. the L-shape image will be ‘invisible’ to the cone-cells because it will mash up in a blend of color, but the rod-cells will perceive it clearly—WHEN THE EYEBALL IS POINTED NEAR IT.
if we have an ambitious software-coder reading this, some kind of recognition-engine could possibly be written that would be able to isolate & emphasize these images. then, if nothing else, we’ll at least be able to see clearly what the bad guys are trying to get up to.
p.s. - i’m pretty sure they’ve already thought of this & are using it; hopefully, i haven’t just given them a really ‘good’ idea, but i tend to think they figured this one out at least 50 years ago.
