Abstract: An exemplary method includes an adjunct content presentation system including adjunct content within a first image of a media content instance by setting a pixel value of a first group of pixels included in the first image to be greater than a predetermined neutral pixel value, including the adjunct content within a second image of the media content instance by setting a pixel value of a second group of pixels included in the second image and corresponding to the first group of pixels to be less than the predetermined neutral pixel value, and presenting the first and second images. The respective pixel values are set to result in the adjunct content being perceptible to a first viewer viewing only one of the first and second images and substantially imperceptible to a second viewer viewing both the first and second images. Corresponding methods and systems are also disclosed.
