  • Patent number: 8610955
    Abstract: In image processing, it is possible to suitably reduce density unevenness and graininess according to the ink used in printing. More specifically, when dividing multi-valued data and generating data for 2-pass multi-pass printing, in addition to divided multi-valued data for each of the two passes, divided multi-valued data that is common to the two passes is also generated. Moreover, quantized data of that common multi-valued data is reflected on the quantized data for each of the passes. Furthermore, when generating the quantized data, the division ratios used when generating the common data using the aforementioned multi-valued data division are set according to the colors of ink used in printing. By doing so, it becomes possible to suitably reduce density unevenness and graininess according to the colors used in printing.

  • Patent number: 8605330
    Abstract: An image processing apparatus and an image processing method are provided which, when forming an image using a plurality of different sizes of dots, can produce a satisfactory image free from problematical levels of density unevenness, graininess and insufficient density with any of these dot sizes. To this end, when printing on pixel areas of a print medium by a plurality of relative movements between the printing unit and the print medium, the dot overlap rate of a dot size that tends to show density unevenness is set higher than that of a dot size that tends to show other image impairments more conspicuously than the density unevenness. This results in a satisfactory image that eliminates such image impairments as density unevenness, graininess and density insufficiency in the entire grayscale range.

    Abstract: An air-condition system includes an air-conditioner having a main blower, a main duct and a heat exchanger, a suction port disposed near a seat, and a sub duct of which one end is connected to the suction port. The air-conditioner suctions air into the main duct through the sub duct, and blows the air into the passenger compartment again. According to the air-condition system, the conditioned air blown out into the passenger compartment is suctioned from the suction port disposed near the seat. Therefore, the conditioned air is recovered and a flow of conditioned air backward from the suction port is restricted, so that comfortable zone air-conditioning can be done. It is unnecessary to provide a heat exchanger used only for zone air-conditioning and thereby simplicity of the system configurations and cost reduction can be brought.

  • Patent number: 8540345
    Abstract: When a gradation mask is used to distribute image data to be recorded by overlapping portions in an overlapping head, color unevenness is generated in an image recorded by the overlapping portions due to a displacement in impact positions caused by an assembly error. As a result, accurate colorimetric measurement of patches recorded by the overlapping portion cannot be performed. To solve such a problem, a distribution ratio by which the image data is distributed to the overlapping portions is set to be approximately constant when recording a test pattern for performing color correction, as compared to when normally recording the image.

  • Patent number: 8529006
    Abstract: Provided are an image processor and an image processing method that are capable of suppressing both density unevenness due to printing position shifts among a group of dots printed by a plurality of relative movements (or a plurality of printing element groups) and graininess. In order to accomplish this, a dot overlap rate in the printing mode in which the density unevenness stands out is made higher than the dot overlap rate in the printing mode in which other defects stand out more than the density unevenness. By doing so, it is possible to suitably adjust the dot overlap rate according to the image characteristic, and output an image having no density unevenness or graininess.
