Embodiment Construction

[0037] Hereinafter, a first exemplary embodiment of the present invention will be described in detail with reference to the drawings.

[0038] first exemplary embodiment

[0039] figure 2 An appearance of an inkjet recording apparatus (hereinafter also referred to as a printer) according to the present exemplary embodiment is shown. This printer is a so-called serial scan type printer, and records images by relatively scanning the recording head in a cross direction (X direction) perpendicular to the conveyance direction (Y direction) of the recording medium 3 .

[0040] will refer to figure 2 An outline of the structure of the inkjet recording apparatus and the operation at the time of recording will be described. The recording medium 3 is conveyed from the reel 6 for holding the recording medium 3 in the Y direction by a conveying roller not shown in the figure via gears. On the other hand, in a predetermined conveyance position, the carriage unit 2 is scanned along ...

Abstract

With respect to an area quantized by using an area of part in a quantization pattern and also without using an area of the other part in the quantization pattern in quantized data, a mask pattern part corresponding to the area of the part among mask pattern parts constituted by dividing a mask pattern is applied.

Description

technical field [0001] The present invention relates to an image processing device and an image processing method. Background technique [0002] An image recording apparatus configured to record an image by repeatedly performing recording scanning and sub-scanning has been proposed. In recording scanning, ink is ejected while a recording head including an ejection orifice array in which a plurality of ejection orifices for ejecting ink is arranged relatively moves with respect to a unit area of ​​a recording medium. In sub-scanning, the recording medium is conveyed. In the image recording apparatus described above, a so-called multipass recording method is proposed in which recording scanning with respect to a unit area is performed multiple times to form an image. [0003] According to the multi-pass recording method described above, generally, multivalued data corresponding to an image to be recorded is quantized to generate quantized data, and furthermore, the quantized...
