Oh, golly. I work in broadcast (though not news.) ALL, and I mean
ALL, news, documentaries, etc., etc. 'erase' some of the truth
via editing, in what they decided to shoot and in what they never
bothered to film in the first place. Taking out flashes in a news
conference is the very LEAST of the 'erasing of truth' that goes
on. It is all biased in one way or another. It can't be helped --
we're humans. Even if we try to be absolutely unbiased, we are
riddled with culture, thought patterns, values that we cannot
keep out of our communication. I'm afraid you're not getting
'truth' via broadcasts -- your getting the broadcasters' (or
advertisers?) interpretation of the truth.
OK, off the soapbox....
My guess is that it is strictly a cost issue. Much cheaper just
to verbally warn people who have issues with flashing lights. Do
glitzy stuff like lines and graphics on a football field can
attract millions of football fans, nicely packaged up for the
advertisers. Worth the cost. Edit out the flashes, and gain a
handful of viewers who suffer from certain disease? Doesn't pay....
Also, taking out a random flash here and there is relatively easy
and would not noticeably affect the picture. However, say the
president grimaces -- every camera/flash in the place goes off,
giving you mostly flashes for a second or two. Taking those out
would do very noticeable 'damage' to the picture. Most viewers
will not notice a single dropped frame. But when you start
dropping 30 to 50% of the frames, they'll notice!

I've often thought that if I had *any* technical question, I could ask
this list and there would be someone who knew (or at least had a very good
idea of) the answer. So here goes ... :-)
Every night when I watch the news on TV, they say something like "Here's
(John Smith) at the news conference held this afternoon. Warning - this
report contains some flash photography".
Now I know why they give this warning - that repeated rapid flashing from
still cameras can cause problems for nystagmus, epilepsy and various other
disease sufferers.
What I don't know is why they don't just digitally edit out the flashing.
Surely this must be (relatively) easy Digital Video Processing - you detect
a non-trivial part (10% threshold??) of the frame which increases in light
level for a single frame (assuming anything between 20 and 60 fps) and then
returns to its original levels.
OK - I know almost nothing about DVP, but if they can overlay a touchdown
line on a football field, or change a Coke to Pepsi can, or all those other
marvels, surely it can't be that hard to eliminate 95% of the flashing -
and wouldn't that would be enough to reduce it below the trigger point for
most vulnerable viewers. It needn't even be done in real time - it could be
left as a warning for any live showing, and then automatically removed by
program and checked by a human editor before subsequent showings.
