Sick is right, but I have always heard that the technology exists, where people can peer at you through your TV set, and you would never know it. I wonder if there really is something to that?
The TV would need an image camera to do that. I doubt it unless one’s built into the cable box.
Back in the pioneer days of TV, it was done by shining a moving point light of constant intensity at the scene being televised and then picking up the reflected light with a stationary photo-eye. The image was reconstructed with a similar moving point light, except modulated by the signal from the photo-eye.
Except to the extent one could perform such a moving spot scan, there would not be any way to visualize what is standing in front of the CRT or flat-screen by means of using a stationary photo-eye. It might be able to pick up something shadowy and vague and infer whether a person is there or not. It couldn’t see the features of the person or determine how he is dressed, etc.
You're not going to wear *that* again today, are you? :O
Had a great aunt who refused to watch Ed Sullivan without her hair and makeup done. Didn't want him seeing her looking like a mess. Is this what you mean?
