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.

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.

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.

An image data of an original is recorded on a pixel unit to a computer and the recorded image data of the computer is applied with image processing to form a subtractive color image data of predetermined number of color of beads based on the size of a bead picture to be prepared and the size of a bead sphere to be used.

A most used color that is a most popularly used color is obtained in an image. Pixel groups formed of continued pixels having an identical color other than the most used color in the image is extracted as first pixel groups. Pixel groups having a color of which a color difference with respect to the most used color is smaller than a predetermined threshold and having a size thereof that is smaller than a predetermined size is extracted as third pixel groups among the first pixel groups thus extracted. The first pixel groups other than the third pixel groups are taken as second pixel groups. An image is generated by replacing colors of portions, which correspond to the second pixel groups in an image having an area identical with that of an image to be processed and filled with the most used color, with the corresponding second pixel groups, respectively.
