Title:
プロジェクタによって投影される画像を生成する方法及び画像投影システム
Document Type and Number:
Japanese Patent JP5813751
Kind Code:
B2
Abstract:
An image projection method for a system comprising a first image projector (1) and a second image projector (2), where the first and second image projectors project overlaid images onto a projection surface (3), resulting in a superimposed image, characterized by:
i) threshold limiting and constrained smoothing filtering an input (source) image (4) by:
a) splitting (separating) the input (source) image into first image , clamped to a threshold (T), and second image, being the remainder;
b) smoothing the second image to reduce content of high frequency components;
c) keeping the the sum of the two images identical to the input source image;
ii) whereby, when the first projector (1) is projecting the first projector image and the second projector (2) is projecting the second projector image, the overlaid image formed on the projection surface (3) essentially corresponds to the input image (4), and where the amount of high spatial frequencies is lower in the second projector image than in the first projector image.
