1. A method comprising:
including, by an adjunct content presentation system, adjunct content within a first image of a media content instance and a second image of the media content instance by setting a pixel value of a first group of pixels included in the first image and a pixel value of a second group of pixels included in the second image and corresponding to the first group of pixels to each be greater than a predetermined neutral pixel value; including, by the adjunct content presentation system, the adjunct content within a compensating image by setting a pixel value of a third group of pixels included in the compensating image and corresponding to the first and second groups of pixels to be less than the predetermined neutral pixel value; and presenting, by the adjunct content presentation system, the first image, the second image, and the compensating image; wherein
the pixel values of the first, second, and third groups of pixels are set to result in the adjunct content being perceptible to a viewer wearing three-dimensional (“3D”) viewing glasses during the presentation of the first image, the second image, and the compensating image and substantially imperceptible to another viewer not wearing 3D viewing glasses during the presentation of the first image, the second image, and the compensating image;the pixel value of the first group of pixels included in the first image and the pixel value of the second group of pixels included in the second image are both substantially equal to one pixel value unit greater than the predetermined neutral pixel value; andthe pixel value of the third group of pixels included in the compensating image is substantially equal to two pixel value units less than the predetermined neutral pixel value.
