A computer analyzes submitted data to identify insufficient data among data necessary for executing C×F color conversion process. When spectral characteristic data of a patch constituting a C×F chart is insufficient, a computer supplements the spectral characteristic data. When complete printing order data has not been obtained, the computer supplements printing order data. The color conversion process is performed using the data after supplement.

Kits, diagnostic systems and methods are provided, which measure the distribution of colors of skin features by comparison to calibrated colors which are co-imaged with the skin feature. The colors on the calibration template (calibrator) are selected to represent the expected range of feature colors under various illumination and capturing conditions. The calibrator may also comprise features with different forms and size for calibrating geometric parameters of the skin features in the captured images. Measurements may be enhanced by monitoring over time changes in the distribution of colors, by measuring two and three dimensional geometrical parameters of the skin feature and by associating the data with medical diagnostic parameters. Thus, simple means for skin diagnosis and monitoring are provided which simplify and improve current dermatologic diagnostic procedures.

An information processing device performs processing of specifying a positional relationship between a first printing section and a second printing section based on image capturing data of a test image that is printed on a printing medium by the first printing section and the second printing section in each of which a plurality of printing elements are arranged. The test image includes a plurality of first lines which are printed by the first printing section so as to have printing positions different from each other in a line arrangement direction on the printing medium and a plurality of second lines which are printed by the second printing section so as to have printing positions different from each other in the line arrangement direction. The information processing device contains a printing coordinate acquisition section, a printing position acquisition section, and a positional shift amount calculation section.

Some embodiments provide a mobile device configured to guide a user, via an augmented reality (AR) interface generated by the mobile device, to capture images of the physical object using a camera of the mobile device. The mobile device may be configured to obtain boundary information indicative of a boundary enclosing the physical object (e.g., a box enclosing the physical object). The mobile device may be configured to use the boundary information to determine positions from which the user is to capture images of the physical object. The mobile device may be configured to guide the user to capture the images using the AR interface by guiding the user to each of the positions in the AR interface (e.g., by generating on or more GUI elements in the AR interface that indicate a position from which the user is to capture an image).

A printer includes a spectroscope and a carriage moving unit. The spectroscope includes a wavelength-selective interference filter on which light from a measurement target is incident, and the carriage moving unit moves the spectroscope in an X direction with respect to the measurement target. If the measurement target is a color patch, the spectroscope performs spectrometry by changing a wavelength of light passing through the wavelength-selective interference filter in a first period during which the spectroscope is moved in the X direction, and passes light of an initial wavelength through the wavelength-selective interference filter at a start of measurement and at an end of measurement in the first period. A first output value that is a measured value from the spectrometry at the start of measurement is compared with a second output value that is a measured value from the spectrometry at the end of measurement.

In an image correction apparatus, an image correction method, a program, and a recording medium, by an imaging apparatus, a video image in which a correction chart is captured is acquired, and the video image in which an object having a sheet shape is continuously acquired at least one of before or after the correction chart is captured. A plurality of correction chart images in which the correction chart is captured and a plurality of object images in which the object is captured are extracted from a plurality of frame images included in the video image. A correction parameter for correcting a representative object image of the plurality of object images is generated based on the plurality of correction chart images, and the representative object image is corrected using the correction parameter.

In a case where a sample color is outside a color reproduction range of an image forming apparatus, there arises an issue that an adjustment target color cannot be brought close to a user-desired color. An image forming apparatus includes a generation unit configured to cause a printing unit to print a plurality of colors close to an acquired sample color and generate a color conversion table based on a user-selected color among the plurality of printed colors in a case where it is determined that the acquired sample color is outside a color reproduction range of the image forming apparatus, whereas in a case where it is determined that the acquired sample color is not outside the color reproduction range, the generation unit generates a color conversion table without causing the printing unit to print the plurality of colors close to the sample color.

An image processing apparatus includes circuitry that acquires a colorimetric value for each of a plurality of patches on a first chart printed out by an image forming apparatus and read by a colorimeter. Each of the patches has a monochromatic color. The circuitry further acquires a maximum tone value previously set in accordance with a sheet, and converts each of the colorimetric value, the maximum tone value, and a color system value of a first target into a particular color value. The first target represents an ideal characteristic of the color system value corresponding to a tone value. The circuitry further determines, as a second target, a characteristic passing through a point determined by a color value corresponding to the maximum tone value. The characteristic is generated based on the color system value of the first target converted into the particular color value.

A printing device comprises a head configured to print an image having a plurality of pixels on a printing medium based on image data, an input device configured to obtain an input of designating a pixel of the image, and a controller. The controller is configured to cause the printing device to print, on a same printing medium, a first patch group containing a plurality of patches, and a second patch group containing patches corresponding to the designated pixel designated via the input device, the second patch group containing a pair of patches, a color difference of the pair of patches contained in the second patch group being smaller than a color difference of a pair of patches with a smallest color difference among the plurality of patches contained in the first patch group.

A code reader includes a color imager and a processor operably coupled to the color imager. The processor is configured to: set an RGB imager pixel color gain; capture at least one image with active or ambient illumination using the color imager with a calibration target in view; calculate a mean value of R, G, B pixels for the at least one image; use a color plane as a reference, determining a color gain to set calibration parameters; capture at least one additional image using the calibration parameters; and save the calibration parameters if mean values of the R, G, B, pixels for the at least one additional image are within a predetermined range to be used by the camera for subsequent image capture, and apply to each pixel of the image a corresponding color correction matrix from among a plurality of stored color correction matrices.
