Subtractive color, or "subtractive color mixing", predicts the spectral power distribution of light after it passes through successive layers of partially absorbing media. This idealized model is the essential principle of how dyes and inks are used in color printing and photography where the perception of color is elicited after white light passes through microscopic "stacks" of partially absorbing media allowing some wavelengths of light to reach the eye and not others.

Syntheses of a new blue EC monomer (ProDOT-MePro), and a new red EC monomer (ProDOP-Et2) are described. Two additional new types of EC monomers based on 3,4-alkylenedioxythiophene include fluorinated EC monomers and an EC monomer including silicon. EC polymer devices having more than one different color EC polymer to enable additional colors to be provided using subtractive color mixing are also described, as well as EC polymer devices incorporating a logo, image, or text, are generally obscured when the device is colored, but become visible when the device is not colored. Also described are EC polymer devices that include a cathodic EC polymer layer, a gel electrolyte, a counter electrode, and a reference electrode. Working prototypes of such devices exhibit significant increases in the speed of transition of the EC device from a colored state to a transparent state.

Image processing device and recording medium
InactiveUS6873436B1Improve image qualitySame resolutionImage enhancementDigitally marking record carriersImaging processingImage resolution
An image processing apparatus and a recording medium which can improve the quality of a color document image are provided. An input image is converted into an image having low resolution. A subtractive color image is generated using the converted image having low resolution. From the subtractive color image, adjacent pixels which are allocated to the same representative color are unified so as to extract an FCR (Flat Color Region) candidate region. A region candidate is redetermined using an image having resolution which is higher than the subtractive color image. Next, a boundary of the FCR is detected and an ultimate FCR is determined. Selection of a representative color of the determined FCR is carried out, and a specific color processing which replaces a color which is close to a pure color with the pure color is effected. Finally, image regeneration is carried out by overwriting and drawing (synthesizing) the FCR on the input image.

Ultrathin nanostructured metals for highly transmissive plasmonic subtractive color filters
An ultrathin plasmonic subtractive color filter in one embodiment includes a transparent substrate and an ultrathin nano-patterned film formed on the substrate. A plurality of elongated parallel nanoslits is formed through the film defining a nanograting. The nanoslits may be spaced apart at a pitch selected to transmit a wavelength of light. The film is formed of a material having a thickness selected, such that when illuminated by incident light, surface plasmon resonances are excited at top and bottom surfaces of the film which interact and couple to form hybrid plasmon modes. The film changes between colored and transparent states when alternatingly illuminated with TM-polarized light or TE-polarized light, respectively. In one configuration, an array of nanogratings may be disposed on the substrate to form a transparent display system.

Photographing apparatus and signal processing method that allow data of still pictures to be converted into a moving picture file
When an animation mode is designated, still picture data that has been photographed or discretely read from a record medium is compressed in a subtractive color process and a data compressing process corresponding to the LZW method. The compressed data is converted into an animation GIF file of which still picture data is combined in the time sequence and it is correlatively displayed on the time base. When an animation mode completion command is input or the size of the GIF file becomes a recordable size of the external storage medium 8, the GIF file data is written to the external storage medium 8. In addition, after a photographed still picture is recorded to the external storage medium 8, an animation can be created. In addition, an animation GIF file can be created using a plurality of still pictures recorded in the external storage medium 8. In addition, an animation GIF file that has been created can be edited.

A control interface for producing a composite color through the mixing of primary colors selected from a first color spectrum including red, yellow, and blue, resulting in the display of said composite color through a light array containing lights of a second primary color spectrum is disclosed. The user selects a color or colors from the first primary color spectrum, and a circuit and control algorithm controls the relative intensities of the colors comprising the second primary color spectrum, rendering the selected color or a mix of previously selected colors through the light array. Through the selection and graduated combination of the primary colors of the first spectrum, the creation of a wide range of colors in the visual spectrum is obtained for lighted color applications. When the first spectrum comprises the primary colors of red, yellow, and blue, the user is able to use the familiar three-primary, three-secondary color wheel, used in art education and taught in elementary school, for their color combination reference. The color selections from the first spectrum are coded to produce corresponding electrical signals to control the output of the light array to establish the proper mix of colors that displays the selected color.
