An illumination condition, which is used to irradiate a print product with light having illuminance higher than normal illumination, is derived based on exposure condition information at the time of photographing.

Information processing apparatus, control system, image processing system, and information processing method to derive illumination condition based on exposure condition

An apparatus is configured to determine an illumination condition for irradiating a printed product with light. The printed product is generated by outputting an image onto a recording medium based on fed input image data. The apparatus includes an input unit configured to receive inputs of luminance dynamic range information of the input image data and exposure condition information at the time of imaging regarding the input image data, an acquisition unit configured to acquire characteristic information of the recording medium, and a determination unit configured to determine the illumination condition based on the luminance dynamic range information, the exposure condition information, and the characteristic information.

Apparatus, system, and method

With an ink jet head having for each color two parallel columns of nozzles arranged shifted by one-half the pitch, odd-numbered rasters and even-numbered rasters are printed by the two nozzle columns. The registration between the odd- and even-numbered rasters is secured during the printing to produce a high quality image. The ink ejection timing between the two raster groups is shifted by a predetermined interval to form adjustment patterns; the adjustment patterns are checked and, according to the check result, an adjustment value for the ink ejection timing between the two ink nozzle columns is entered, and the entered adjustment value is stored to be reflected on the actual printing operation. To facilitate the adjustment pattern check, the adjustment patterns have a dot distribution with a blue noise characteristic at a resolution at which the printing apparatus can print.

Provided is an inkjet printing apparatus that, when performing multi-pass printing using pigmented ink and image enhancing liquid for adjusting the glossiness, is capable of outputting a high-quality image in which gloss unevenness due to displacement of the printing position cannot be noticed. In order to accomplish this, dot arrangement data is generated based on input image data so that the dot arrangement of image enhancing liquid includes a greater low-frequency component in the spatial frequency than the dot arrangement of colored ink on a print medium. As a result, it is possible to suppress gloss unevenness even when printing position displacement occurs, while at the same time suitably suppressing a feeling of graininess in colored ink.
