摘要： A print media (200) comprises paper or other substrate, on which image content, whether text or images are printed with accompanying hidden data (220). The image content is printed with one or more normal printing process visible colorants (340), while the hidden data (220) is printed with spectral edge markers (320). The spectral edge marker materials (320) have a substantial spectral absorption just outside the human visible spectrum, and only slight visible absorption, which is masked by the visible colorants (340). Although the hidden data is nominally visually imperceptible, an image capture device (250) having a visible spectral response that extends into a spectral region just outside the visible spectrum where the spectral edge marker absorption occurs, can then detect the hidden data.

摘要： A method for providing digital watermarking for text or images that uses spectral edge marking materials (320) printed on a print media (200) to embed hidden data (220). The spectral edge markers (320) have an absorption spectrum at the edge of the human visible spectrum, either at the UV edge or IR edge, which provides an optical density that is generally imperceptible to humans, but which can be detected by an image capture device (250). The crosstalk of visible optical absorption provided by these materials is largely masked by the presence of visible colorant(s) (340), with only small color differences between areas with and without the spectral edge markers (320). The image capture device (250) has a visible spectral response that extends into a spectral region just outside the visible spectrum where the spectral edge marker absorption occurs, and can be operated to detect the hidden data.

摘要： A method and apparatus for capturing image data from multiple image sensors and generating an output image sequence are disclosed. The multiple image sensors capture data with one or more different characteristics, such as: staggered exposure periods, different length exposure periods, different frame rates, different spatial resolution, different lens systems, and different focal lengths. The data from multiple image sensors is processed and interleaved to generate an improved output motion sequence relative to an output motion sequence generated from an a single equivalent image sensor.
