- I guess you may need a 50 mp or so digital camera. But I am not sure if my guess is correct.
Suppose 100 ppi big screen is clear enough for our eyes. Your 100 inches projector screen is about the size 60x80 (100^2 = 60^2 + 80^2). So
vertical: 100 x 60 = 6,000 pixel
horizon: 100 x80 = 8,000 pixel
total 6,000 x8,000 = 48,000,000 pixel= 48 mega pixel
I heard Canon currently is developing 50 mp digital camera.

谢谢这么多位的交流。要使图像清晰投影到大屏幕（比如说１００吋）像片分辩率至少要多大？
