51 results about "Complementary colors" patented technology

Complementary colors are pairs of colors which, when combined or mixed, cancel each other out (lose hue) by producing a grayscale color like white or black. When placed next to each other, they create the strongest contrast for those two colors. Complementary colors may also be called "opposite colors."

Method and device for reducing flicker of consecutive pixels of temporally alternating complementary colors - Patent Application 20070122999

The method and device enable reducing the energy required to render an image by replacing pixels of the image with temporally consecutive pixels of alternating complementary colors that require less energy to display and are selected according to a polarity constraint. This solution exploits the flicker fusion property of the human visual system, which allows selecting complementary colors that can visually have the same perceptual properties as corresponding monochrome colors. The alternating complementary colors are selected to be more economical in terms of the energy consumption required to render the colors. This replacement is performed by either frame doubling, frame skipping, or frame averaging. The concept of consecutive pixels is temporal. In other words, when using frame doubling, one pixel is replaced by two temporally consecutive pixels of alternating complementary colors, with the replacement pixels having half the duration. When using frame skipping or averaging, two temporally consecutive pixels are replaced by two temporally consecutive pixels of alternating complementary colors, with the replacement pixels having the same duration. The polarity constraint enables a reduction in perceived flicker. The association between colors and corresponding alternating complementary colors can be obtained from a lookup table. These principles can be used for videos containing an image or a sequence of images.
