摘要： An image processing apparatus (Fig.1) divides an input image into a plurality of band area images, stores the respective band area images in a band memory, and performs image processing. The apparatus comprises: storage means (110) for storing filter coefficients having a two-dimensional reference area of M pixels in a first direction and N pixels in a second direction orthogonal to the first direction; and spatial filter means (230) for applying, to the band area image stored in the band memory, a spatial filter using the filter coefficients. The filter coefficients are set as the filter coefficients so as to refer to pixels for every K pixels in the second direction, and the spatial filter means sequentially applies the spatial filter to the band area image K times in the second direction.

摘要： There is provided an image processing method in which in a full line type inkjet printer using a connecting head having an overlap region, even if a conveyance direction of a print medium is more or less inclined, a density change or degradation of graininess is not introduced. Therefore, an image data in a non-overlap region is distributed to a plurality of nozzle arrays such that ink is ejected from all the plurality of the nozzle arrays. On the other hand, a region where a print allowance rate changes in the overlap region is divided into plural regions, and the image data is distributed to the plurality of the nozzle arrays such that these regions are located to be shifted.

摘要： A reactive color ink that contains a metal ion and exhibits mutual reactivity with a black ink is applied in an area including a print area 1, which has been formed by applying the black ink on a recording medium, and an area surrounding the print area 1, a distance between an edge of the print area 1 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 1 and the surrounding area) is multiplied by (a print duty (%) of the reactive color ink applied in the area including the print area 1 and the surrounding area).

摘要： A print apparatus which receives image data from a digital camera, PC card, or PC to print an image on a storage medium outputs print data based on image data from the PC to a printer engine via a USB hub, and prints an image. The apparatus has a DSP which receives compressed image data from the digital camera or PC card, decodes the received data, and parallelly executes, for the decoded image data, at least color space conversion processing, size change processing, and color conversion processing. The apparatus generates print data on the basis of the image data processed by the DSP, outputs the generated print data to the printer engine, and prints an image.

摘要： A recording system for printing a high resolution image. Low resolution print data is transferred from the host computer to the printer and expanded into high resolution print data in the printer, such as by using a predetermined pixel pattern or a pattern key. The pixel pattern is changed in each of the plurality of printing scans, such as by changing the scanning frequency, to eject additional ink droplets per pixel. An image process, such as an output correction process, is performed by the host computer to determine the pixel pattern and pattern key information for printing a high resolution image. Also, power required to be supplied to the print head is reduced by changing the pixel pattern.

摘要： An ink jet printing system having a preheating system for preheating ink during non-printing periods. The system receives print data and commands, feeds paper into the ink jet printer (10) in response to the receipt of print data and commands, detects an ambient temperature within the ink jet printer (10) and determines if the ambient temperature is above a predetermined threshold temperature, preheats the ink supplied to a print head (50a,50b) in the ink jet printer (10) during feeding of paper in the case the detected ambient temperature is below the predetermined threshold temperature, moves a printer carriage carrying the print head (50a,50b) from a non-printing area to a printing area so as to print the print data. During the moving of the carriage from a non-printing area to a printing area, the ambient temperature is again detected and it is determined again if it is below the predetermined threshold temperature and, in the case that it is, the ink supplied to the print head (50a,50b) is preheated during the moving of the printer carriage in the non-printing area.

摘要： Printing which accommodates carriage speed non-uniformities by allowing both forward and reverse printing despite the presence of ringing and other overshoot anomalies in carriage printing speed. A determination is made as to whether print data for a current scan and a prior scan overlap in either of two critical zones at lateral extents of the recording medium, where carriage speed ringing and overshoot non-uniformities are most prevalent. If print data for a current scan and a prior scan overlap in either of the two critical zones, the current scan is printed in the same direction as that of the prior scan. On the other hand, if print data for the current scan and the prior scan do not overlap in either of the two critical zones, then printing of the current scan is effected in a direction opposite to that of the prior scan.
