    摘要: When a plurality of sheets of images are laid out and outputted in one page and characteristic amounts of multivalued image data are obtained to perform preferable image correction, the characteristic amounts of all the images to be recorded in the corresponding page have been beforehand obtained to calculate preferable image correction parameters. Therefore, a waiting time until the start of actual printing has been long. To resolve such an inconvenience, an image processing apparatus of the present invention includes a correction amount deciding unit for deciding or determining an individual correction amount with respect to each of the plurality of image data, and a correcting unit for correcting the image data based on the individual correction amount, whereby the correcting unit respectively corrects the images in accordance with the correction amounts which have already been decided, in a state where the correction amount deciding unit has not completed the decision of the correction amounts for all of the image data.

    摘要: Pixels in a window, which corresponds to the position of an input pixel and has a predetermined size, are extracted from a reduced image obtained by reducing an input image to a predetermined scale. Substitute data used to substitute the value of the input pixel is generated based on the extracted pixels in the window. The difference value between the substitute data and input pixel value is calculated and is compared with a first threshold value. When the difference value is smaller than the first threshold value, the input pixel value is substituted by the substitute data. Thus, low-frequency noise reduction can be attained using a minimum required memory size while suppressing adverse effects such as a resolution drop and the like.

    摘要: Upon outputting halftone image data to an output device, density transformation is prevalently done to improve image quality. Density transformation corresponds to linear gamma correction, and cannot correct any color fog and the like of a photo image. Hence, lightness/color difference information of halftone image data is acquired on the basis of low-frequency components of frequency data obtained by transforming halftone image data into spatial frequency components, and a lightness/color difference transform amount of the halftone image data is set on the basis of the acquired lightness/color difference information.

    摘要: This invention has as its object to receive image data from image sensing apparatuses of various manufacturers and to print a high-quality image by making image data transfer and a printing instruction, which are independent from interfaces. Since an image sensing apparatus such as a digital camera or the like calculates image feature amounts, and transfers the calculation result to a printing apparatus, huge image data need not be transferred from the image sensing apparatus to the printing apparatus again and again, and a high-quality image can be output. Upon printing image data transmitted from a digital camera (DSC) (3012) to a PD printer (1000), after a protocol is established by applications (NCDP) installed in the PD printer and DSC, the PD printer transmits its Capability list to the DSC. The DSC calculates an image feature amount of a selected image to be printed, and transmits the calculation result to the PD printer. Upon reception of this information, the PD printer makes image correction based on that image feature amount, and records (prints) an image.

    摘要: A reactive color ink that contains a metal ion and exhibits mutual reactivity with a blank ink is applied in an area including a print area, which has been formed by applying the blank ink on a recording medium, and an area surrounding the print area, a distance between an edge of the print area and an outer edge of the surrounding area being up to four pixels. This ink application is performed so that a value at least equal to 0.01 is obtained from a calculation where a metal ion concentration % by weight in the reactive color ink applied in the area including the print area and the surrounding area is multiplied by a print duty % of the reactive color ink applied in the area including the print area and the surrounding area.

    摘要: An ink jet recording method effects recording on a recording material by ejecting ink comprising coloring material and reaction liquid reactable with the ink from an ink ejection portion for ejecting the ink and a reaction liquid ejection portion for ejecting the reaction liquid. The method includes a recording step of effecting the recording selectively in a first recording mode in which no margin is provided at least one end portion of the recording material and a second recording mode in which margins are provided at all of the end portions of the recording material. A recording condition in the first recording mode and a recording condition in the second recording mode are different.

    摘要: Image data, or RGB luminance data input from a host computer, is color-converted by LUT into 8-bit CMYK density data for each ink color. The CMYK density data is divided into predetermined regions and, based on a gray scale value for each of the divided regions, ink application volumes are calculated. According to the calculated ink application volumes, the 8-bit processing liquid application data S is generated. Then, the CMYK density data and the processing liquid application data undergo output gamma processing, after which they are quantized by a quantization processing unit into 1-bit ejection data for each nozzle.
