A method is performed at a system that comprises one or more video cameras and a remote server system. The method includes obtaining, via a video camera of the one or more video cameras, a continuous stream of video data for a scene. The video data stream comprises color video data in accordance with a determination that the scene has illumination above an illumination threshold and comprises infrared (IR) video data in accordance with a determination that the scene does not have illumination above the illumination threshold. The method includes colorizing the IR video data based on a subset of the color video data. The method further includes presenting the colorized video data to a user in real time.

An image forming apparatus includes an image formation unit configured to form an image on a sheet at a formation position; a circulatory conveyance path for conveying the sheet with the image formed at the formation position on a first side thereof to the formation position again; a reading unit configured to read the first side of the sheet conveyed through the circulatory conveyance path and output image information; and a conveyance control unit configured to convey the sheet in one conveyance mode out of a plurality of conveyance modes when the reading unit reads the first side of the sheet. A range, in a conveyance direction, of the sheet that can be read by the reading unit while a conveyance speed of the sheet is constant is different for each of the plurality of conveyance modes.

A method of color mapping color values of an oligochromatic pattern comprising the following steps: determining an image-gamut, in a N-dimensional device independent color system (ND-DICS), of said oligochromatic pattern; wherein said image-gamut comprises said color values of said oligochromatic pattern; and determining a skeleton (500) of said image-gamut; and performing an adaption on said skeleton (500) in said ND-DICS by a set of N-dimensional-transforming steps (30) and determining for points of said skeleton (500), a path in said ND-DICS that corresponds to said adaption; and color mapping said color values, of said oligochromatic pattern, based on said determined paths (35) of said points of said skeleton (500).

A display device includes a first substrate, a red sub-pixel, a green sub-pixel, a blue sub-pixel, a plurality of photosensitive devices, and a second substrate. The red sub-pixel, the green sub-pixel, and the blue sub-pixel are located on a first side of the first substrate. The photosensitive devices are located on the first side of the first substrate. Each of the photosensitive devices overlaps at least one of the red sub-pixel, the green sub-pixel, and the blue sub-pixel. Each of the photosensitive devices includes an active element and a photosensitive element. The active element is located on the first substrate. The photosensitive element is electrically connected to the active element. The second substrate overlaps the first substrate.

Provided is an image forming apparatus that speeds up the auto color mode. The image forming apparatus includes a document reading unit that reads a document including a plurality of pages and outputs image data and can determine whether the document is a color document or a monochrome document. In the document read by the document reading unit, when monochrome pages of the first specific number of pages or more continues in the same job, a document determining unit predicts that the subsequent page is also determined to be a monochrome document. When the document is predicted by the document determination unit to be a monochrome document, an image processing unit performs monochrome image processing for the monochrome document on the image data immediately after reading.

A method of visualization, characterization, and detection of objects within an image by applying a local micro-contrast convergence algorithm to a first image to produce a second image that is different from the first image, wherein all like objects converge into similar patterns or colors in the second image.

Disclosed are a quantum color image encrypting method based on modification direction and corresponding circuit, respectively providing quantum modular circuits design for a parallel adder, a parallel subtractor, a comparator, a cyclic shift add 1, and a cyclic shift subtract 1; and based on these modular circuits, circuit for implementing quantum color image steganography is provided.
