Blocking harmful blue light while preserving image color appearance

Recent study in vision science has shown that blue light in a certain frequency band affects human circadian rhythm and impairs our health. Although applying a light blocker to an image display can block the harmful blue light, it inevitably makes an image look like an aged photo. In this paper, we...

Description
Summary:Recent study in vision science has shown that blue light in a certain frequency band affects human circadian rhythm and impairs our health. Although applying a light blocker to an image display can block the harmful blue light, it inevitably makes an image look like an aged photo. In this paper, we show that it is possible to reduce harmful blue light while preserving the blue appearance of an image. Moreover, we optimize the spectral transmittance profile of blue light blocker based on psychophysical data and develop a color compensation algorithm to minimize color distortion. A prototype using notch filters is built as a proof of concept.
