Take a look at this image. 很好奇你的視力到底多好嗎?看看這張圖片吧 Who do you see? 你看到了什麼 If you're at a normal viewing distance from the screen and have decent eyesight, 如果你在適當的觀看距離,並且視力還不差的話 you should be seeing Albert Einstein. 你應該會看到愛因斯坦 However, if you see Marilyn Monroe, you may want to consider wearing glasses or contacts. 但如果你看到的是瑪麗蓮夢露,你可能就要考慮戴眼鏡或隱形眼鏡了 Wear your glasses right now. Try taking them off and the image may change. 戴上你的眼鏡吧!然後再把眼鏡拿下來,你會發現圖片好像改變了 Or if you're near somebody else, ask them what they see. 或是,如果你旁邊剛好有人,問問他們看到了什麼 The effect can actually be seen by anyone if we change the distance or size of the picture. 任何人都看得到這種變化,只要改變了視距或圖片的大小 If it's far away, you're more likely to see Marilyn Monroe, as our eyes only pick up the broader strokes of an image from a distance. 如果圖片離你很遠,你應該會看到瑪麗蓮夢露,因為我們眼睛只會從遠處看到圖片上比較粗的框線 But as you come closer to the image, you see the finer details of Einstein. 但當你離圖片越來越近時,你會慢慢看到愛因斯坦身上的細節 We promise we haven't changed anything digitally. 我們保證沒有修過圖片 In fact, pause this video now, and try walking away from your computer screen. 事實上,按一下暫停鍵,然後試著離你的螢幕遠一點 Chances are the image will change and at a different distance than your friends because our eyes are all slightly different. 這些圖片很有可能會跟著改變,然後你也會與你朋友站的距離不一樣,因為每個人的視力有高有低 The further away you can stand and still see Einstein, the better your eyes likely are. 當你站在越遠的地方還能看到愛因斯坦,這表示你的視力越好 You can achieve the same effect by squinting your eyes to blur the photo. 把你的眼睛瞇起來直到視線變模糊,這也可以達成一樣的效果 So what's going on? Well this image is an example of a hybrid image, whereby a low spatial frequency of one picture is combined with the high spatial frequency of another. 所以為什麼呢?是這樣的,這張圖可以算是混疊圖像的一種,其中高低不同的空間頻率會混和在一塊 But depending on how well you're able to focus or pick up contrast, your eye will only pick out certain details. 取決於不同眼睛對焦及判斷對比的能力而定,你的眼睛只會從圖片抓出一些特定的細節 Up close, we're generally able to see fine details like Einstein's mustache and wrinkles. 近點看,我們大多能看到愛因斯坦清楚的細節,像是鬍子及一些皺紋 But as the distance increases, or if your vision is poor and creates a more blurred image in the first place, 但隨著距離增加,或是你的視力本身就不好,一開始你會看到比較模糊的圖片 Your ability to pick up details fades away. 你看到細節的能力會逐漸減弱 Instead, you only see the general features like the shape of the mouth, nose and hair, making it seem like Marilyn Monroe. 相反地,你只會看到一些比較普通的細節,像是嘴巴的形狀、鼻子及頭髮,讓這人像趨近於瑪麗蓮夢露的樣子 Love tricking your brain with illusions? 喜歡挑戰這些錯覺嗎?
