A method of splitting an image into a white layer and a color layer, comprising: providing an electronic application; receiving and loading, by the electronic application, an image file; the image file comprises a C color plane, a M color plane, a Y color plane, a K color plane, and a W color plane; splitting the image file to create a white layer and a color layer; erasing the K color plane; generating a CMY color plane; outputting the CMY color plane to a first storage location, to generate the color layer; copying, in the electronic application, the W color plane into the K color plane; erasing the C color plane, the M color plane, and the Y color plane to generate a W to K color plane; and outputting the W to K color plane to a second storage location, to generate the white layer.

The technique of the present disclosure can achieve processing efficiency and prevention of improper drawing in printing a monochrome representation of color data. In performing discriminability reproducing color conversion processing, a PDL analysis unit determines whether processing involving color change that changes the original color is specified in operator information on a target object for the discriminability reproducing color conversion processing. In a case where processing that changes the original color, such as ROP or α-blending, is specified for the target object, the discriminability reproducing color conversion processing for the page is canceled and switched to all-color uniform color conversion processing. This enables both of efficient discriminability reproducing color conversion and prevention of improper drawing.

A visible light sensor (VLS) may be configured to sense environmental characteristics using images of a space. The VLS may be controlled in one or more modes, including a daylight glare sensor mode, a daylighting sensor mode, a color sensor mode, and/or an occupancy/vacancy sensor mode. In the daylight glare sensor mode, the VLS may be configured to decrease or eliminate glares. In the daylighting sensor mode and/or color sensor mode, the VLS may be configured to provide a preferred amount of light and color temperature, respectively, within the space. In the occupancy/vacancy sensor mode, the VLS may be configured to detect an occupancy/vacancy condition within the space and adjust one or more control devices according to the occupation or vacancy of the space. The visible light sensor may be configured to protect the privacy of users within the space via software, a removable module, and/or a special sensor.

Provided is an image processing apparatus that enhances the distinctiveness of document having a color portion and outputs in monochrome. A monochrome visual determination unit determines whether or not the distinctiveness of the color portion is low when the document data having the color portion is output in monochrome. This color portion includes characters, electronic marks, and graphs, and they are after a specific keyword. A monochrome presentation unit presents to a user a warning or a result of modification when there is the color portion that the distinctiveness is determined to be low by the monochrome visual determination unit. The monochrome presentation unit presents a state in which the document data is output in monochrome by displaying a preview.

Systems, devices, media, and methods are presented for receiving a set of images in a video stream, receiving input that selects an image capture mode icon from a plurality of image capture mode icons; selecting a blur operation from a plurality of blur operations based on the image capture mode icon selected by the input; and modifying the video stream based on the selected blur operation.

A method of forming a data-hiding watermark on a surface may include encoding data within an image using the chrominance data of the of the image, adjusting at least one characteristic of the image to enhance the prominence of the encoded data within the image, and printing the adjusted, encoded image onto the surface.

A method and machine for digital printing with neutral colors, wherein the method uses a digital printing machine which has a print head which in turn has an ejector; providing a substrate for receiving digital printing; providing a printing product which has at least one light black (LK) printing ink having a concentration of black pigment that is lower than that of a black (K) ink; arranging the ejector with the printing product such that it is arranged for ejecting the printing product on the substrate; and performing digital printing on the substrate by means of ejecting the printing product according to a predefined design having at least one neutral color.
