Chatty Hollywood

　　 "The biggest difference between movies and the scenes we see in our lives is that they are not continuous."

　　 Sheldon smugly began to give Emily and Leonard popular science,

"Just like discrete particles can accumulate into a complete object, a movie is actually composed of similar pictures frame after frame. Because of the persistence of human vision, when we see 24 continuously playing within one second When the picture is framed, our eyes will automatically help us to string it together to form a smooth continuous picture, which is a movie!"

　　 "So the movie is also called "24-frame art"!"

　　 Emily sighed.

　　 "But what does this have to do with that female ghost?"

　　 "Of course there is!"

　　 Sheldon was very confident in his guess. He looked like a good teacher to Emily and Leonard.

　　 "Think about it, there are 24 frames of pictures in one second, our eyes can help us to string them into a continuous picture, but what if there is the ghost in only 8 frames, and the other 16 frames don't?"

　　 Seeing Leonard and Emily thoughtfully, Sheldon said the answer directly.

　　 "The image of the female ghost in our eyes will be dimmed by other images, and eventually we can't see it!"

　　 "But on the other hand, we actually saw the image of the female ghost after all, even if the eyes are not noticed, there will be some feeling in the brain after all."

　　 Leonard also understands now,

　　 "That's why when we read it the first time, we always feel that something is wrong."

　　 "Those places are the scenes where the female ghost actually appeared."

　　 Emily suddenly realized, but soon became confused again.

　　 "But even so, it can only explain why we felt something was wrong when we saw it the first time. But when we swipe the second time, why can we see that female ghost again?"

"this……"

　　******************

　　 "That also uses the visual persistence of the human eye!"

　　On the way home, Charlotte is also explaining the last technical mystery to Charlize.

"The first time I watched it, people could not see the picture of Alexis. Although it is a bit strange, it is not a difficult technique in essence. Many TV stations will occasionally insert into it when they broadcast a ball game. The last few frames of landscape paintings, although limited to the number of frames, are invisible to everyone, but they can calm the restless mood of the fans."

　　 "In contrast, it is the most difficult for the second brush viewers to see the scenes of Alexis."

　　 At this point, Charlotte shrugged.

　　 "Anyway, as far as I know, with normal technology, it is impossible for people to see completely different images when watching the projection of the same set of films——"

　　 "Unless you use two different sets of film!"

　　 Charlize said her guess, she has actually been curious about this question for a long time.

　　 "In that case, in addition to the second brush audience, those who watch it for the first time will also see it!"

　　 Charlotte smiled and shook her index finger.

　　 "In this, magic is actually applied."

　　 "Spell!?"

　　 "Accurately speaking, it should be hypnotism, but ordinary hypnotists who don't know how to use magic can't hypnotize them through film."

　　 Charlotte shrugged.

　　 "So it's okay to call it a spell."

　　 "Do you hypnotize the audience through the movie screen?"

　　 Charlize’s curiosity is really aroused now.

　　 "Can you tell me what exactly is your hypnosis?"

"certainly."

　　 Charlotte did not intend to hide,

"Although I know spells, I am not a master in hypnosis. At least, I don't have the ability to hypnotize a person and make him think that he is a duck. What I am good at is to make people use hypnosis. The memory of sound and video is deeper and more real."

　　——Only with this kind of hypnosis, can I make others impressed by the spells when I recite those spells that are made up to deceive people, and then I believe that the spells are really magical.

　　-and what is even more ridiculous is that if they believe it, the spell will really have magical powers and make my spells more effective.

　　 Charlotte complained about the mystery and idealism of his magic system, but he didn’t explain it to Charlize.

"In this "Deadly Bend", I just hypnotize the audience, let their brains remember the female ghost, that is, the scene where Alexis appeared-even when they watched the first time, their eyes I can't notice these pictures at all."

　　 "What's the point of doing this?"

　　 Hearing this, Charlize felt that he was even more confused.

"Of course it makes sense! Imagine if you have a deep memory of a certain shot in the movie, does it mean that when you watch the next time, you just see the scene in front, you will realize in advance that the shot is about to arrival?"

"this……"

　　 Charlize looked back for a while with his head tilted.

　　 "It seems that this is really the case!"

"Under my hypnosis, the viewers who have watched it once did not notice Alexis's lens, but their brains, or subconscious mind, remembered those images deeply. And when they watched the second Over time, the pictures in the subconscious memory will appear in advance, interlacing with the pictures played on the big screen, and finally forming a visible picture of Alexis."

　　 "Staggered?"

　　 Charlize’s expression is obviously a little dazed~www.readwn.com~ Don’t understand? "

　　 The blonde girl nodded.

　　 "Let's put it this way, it is equivalent to the original comic strip with only 12 pages. I copied one more copy and mixed it with the first one by a page-to-page crossover, so that the number of pages doubled."

　　 Charlotte gave a simple example,

"In the original 24 frames played in one second, Alexis would only appear in 8 to 12 frames. At this time, because the number of frames is too few, it is dimmed by other pictures, and the eyes are naturally unable to see. "

"But when those viewers who have watched it once are scanned for the second time, the picture in their subconscious memory, and the picture they saw the second time, add up to 16 to 24 frames in one second with Alexis appearing. The picture is now visible. This frame rate range is gradually visible to the human eye."

　　 "In other words, it is a kind of illusion-like picture that is formed by combining the picture in people's memory with the picture in front of them?"

　　 Charlize tried to summarize,

　　 "Why do I think this is brain supplement?"

　　 "It's okay to say that it's a brain supplement!"

　　Charlotte simply admitted Charlize's statement.

　　 "My technique is originally the result of the subconscious memory of the human brain and the visual residual effect of the human eye. You said it is a brain supplement."

"In fact, this phenomenon is also very common in reality-sometimes we look at something and think preconceivedly what it is, then after we observe it with our eyes, we often feel that it is very similar-this is human The result of the combined effect of his vision and subconscious memory is not much different from my approach!"

　　 "So that's it! This is really like a magician's technique!"

　　 Charlize suddenly realized.
