Showing Different Images to Observers by Using Difference in Retinal Impulse Response

© 2017, Springer International Publishing AG. In this paper, we propose a novel method for displaying different images to individual observers by using the difference of temporal response characteristics of these observers. The temporal response characteristics of human retina have individuality, and thus each observer observes slightly different image, even if the same image is presented to these observers. In this paper, we describe the variety of temporal response characteristics of observers by using the linear combination of impulse response of observers in time domain, and derive an observation model of observers in time domain. By using the observation model, we propose a method for representing arbitrary different images to individual observers. Experimental results from a special camera which reproduces the impulse response of human retina show that our proposed method can represent different and arbitrary images to multiple observers
