摘要： An image recording apparatus for recording an image on a recording medium by causing a recording head having the arrangement of a plurality of recording elements to conduct its main scanning for the recording medium interrelatedly in the direction opposite to the arrangement of the recording elements comprises setting means to set the number of main scannings by the recording head; main scanning means to perform recording by plural numbers of main scannings with respect to one pixel by causing the recording head to conduct its main scannings for the same recording area of the recording medium in accordance with the number set by the setting means; and sub-scanning means to cause the recording head and the recording medium to be sub-scanned interrelatedly per main scanning in an amount smaller than the width of the arrangement of the recording elements of the recording head. Hence, even if a disabled ejection occurs in one scanning at the time of recording by a multi-scanning, the missing dot is complemented by the following scan to make it possible to obtain an image having no image defectives at all times.

摘要： Bit data of the received video signal is partially converted into a first signal representing a data sequence corresponding to a resolution of an LED head (19 in FIG. 1). The first signal is transmitted to the LED head in the form of a real printing data signal to be printed on a basic raster line in synchronism with a line timing signal. The remaining bit data of the received video signal, which are not converted into the first signal, are converted into a second signal representing of another data sequence, and then stored in a line buffer (55 in FIG. 7). The second signal stored in the line buffer is in turn transmitted to the LED head in the form of a real printing data signal to be printed on the additional raster line in synchronism with an additional line timing signal. LED head drive energy with which the the basic raster lines are printed and another LED head drive energy with which the additional raster lines are printed are set independently of each other. The LED head may be provided with such a resolution function.

摘要： After an ink-jet recording head (1) with a plurality of discharging portions (Nos. 1-128) arranged is main-scanned in a direction perpendicular to the direction of the discharging portion arrangement to record a first image area, sub-scanning of the head is performed. Before the head is main-scanned to record a second image area, the sub-scanning is performed so that a few discharging portions (Nos. 1-3) on an upper edge portion of the head (1) in second main-scanning overlap part of the first image area. Ink droplets land on pixels in the overlapping portion twice for each main-scanning, and image density of the pixels in the overlapping portion is controlled by the sum number of the landing ink droplets. This enables image density unevenness of image density, a "black stripe banding" or a "white stripe banding" in a boundary of an image area being recorded in each main-scanning to be markedly reduced.

摘要： A method of compensating the interval of a plurality of pixels to be simultaneously recorded on a recording surface. The plurality of pixels are recorded by a plurality of beams whose light intensity distributions partially overlap with one another on the recording surface and the pixel whose position should be compensated is selected. The light quantity ratio of the plurality of beams for recording the pixel is changed. Since the light quantity is changed, the peak of the density of pixel is shifted on the side of the beam of a large light quantity so that the interval between the pixels can be compensated.

摘要： Amounts of read position errors in subscanning direction with respect to respective scanning positions of line image sensors (CCD 1, CCD 2, CCD 3), which are provided in parallel with main scanning direction, are found in advance by a number of scanning lines. In actual scanning, output image signals from the line image sensors (CCD 1, CCD 2, CCD 3) are delayed, in respective main scanning positions of the output image signals, by respective line numbers corresponding to the respective found amounts of read position errors in the subscanning direction, and are output.
