摘要： An image forming apparatus includes a first printer configured to print on a medium using a first material, a second printer configured to print on the medium using a second material that turns invisible when a first condition is satisfied, and a controller configured to: control the first printer to print on the medium a first symbol that is machine-readable and associated with first information, and control the second printer to print a second symbol on the medium on which the first symbol has been printed. A composite symbol of the first and second symbols is machine-readable and associated with second information different from the first information.

摘要： In a method to improve backwards compatibility when decoding high-dynamic range images coded in a wide color gamut (WCG) space which may not be compatible with legacy color spaces, hue and/or saturation values of images in an image database are computed for both a legacy color space (say, YCbCr-gamma) and a preferred WCG color space (say, IPT-PQ). Based on a cost function, a reshaped color space is computed so that the distance between the hue values in the legacy color space and rotated hue values in the preferred color space is minimized. HDR images are coded in the reshaped color space. Legacy devices can still decode standard dynamic range images assuming they are coded in the legacy color space, while updated devices can use color reshaping information to decode HDR images in the preferred color space at full dynamic range.

摘要： A method for brightness and color correction of image data of a line camera is disclosed, wherein, for the detecting of image data with at least two line arrays of the line camera while illuminating a detection area of the line camera with an illumination module, a gray-scale image and at least two single-color images are recorded, and the image data is corrected with the help of a brightness function of the illumination module which is dependent on a line position of the line array and/or a distance of recorded objects. The brightness function is determined for the illumination module in advance and independent of the line camera and is stored in the illumination module, and the brightness function is read out by the line camera and used for the respective correction of the gray-scale image and the single-color images.

摘要： A printing control system includes a processor configured to: in a case where printing device rows configured by a printing device and a device that executes post-processing of a printed matter printed by the printing device are operated in an identical environmental region, group plural printing device rows in which an optimum environmental condition set for each of plural printing device rows is within a preset range; detect an environmental state of the environmental region in which plural printing device rows are operated; and in a case where the detected environmental state is within a preset allowable range from the optimum environmental condition of certain plural printing device rows that are grouped, operate plural printing device rows that are grouped.

摘要： Techniques for interactively determining/visualizing the color content of a source image and how the corresponding image data is mapped to device colors are described herein. For example, the color content of a digital image can be converted between different color spaces to identify gamut limitations of an output device (e.g., a printing assembly), discover color(s) that cannot be accurately reproduced, etc. Color space conversions enable the transformation of the color content of the digital image from device-specific colorants to a device-independent representation (and vice versa). In some embodiments, these transformations are facilitated using lookup tables that are implemented in graphical processing unit-resident memory.

摘要： An image processing circuit for performing local tone mapping (LTM) after image warping. The image processing circuit includes a warping circuit that warps an input image to generate a warped image, and a LTM circuit coupled to the warping circuit. The LTM circuit determines an input color component value for a color component of a pixel in a version of the warped image, determines an output color component value for the color component of the pixel, based on mapping of coordinates of pixels in the warped image to coordinates of pixels in the input image, determines a gain value for the pixel as a ratio of the output color component value relative to the input color component value, and adjusts color component values for color components of the pixel using the gain value to generate adjusted color component values for the color components of the pixel in an output image.
