20080291473 | IMAGE DATA GENERATING METHOD, PRINTING METHOD, IMAGE DATA GENERATING APPARATUS, AND PRINTER - A head in a printer has an outlet row including a plurality of outlets arranged in a width direction perpendicular to a scan direction. A threshold matrix is stored in a main body control part, and sleep elements representing sleep of ejection of ink are arranged in the threshold matrix at a regular interval in each element row which is a plurality of elements arranged in a row direction corresponding to the width direction. The threshold matrix is compared with a grayscale original image to generate data of a halftone image where during printing, the number of outlets included in each outlet group not brought into sleep state continuously in the width direction is made equal to or larger than 1 and equal to or smaller than a predetermined number. Thus, it is possible to easily suppress occurrence of unevenness in a printed image, caused by cross talk between outlets. | 11-27-2008 |

20130016154 | IMAGE READING APPARATUS, IMAGE INSPECTION APPARATUS, PRINTING APPARATUS, AND CAMERA POSITION ADJUSTMENT METHODAANM Imamura; AtsushiAACI KyotoAACO JPAAGP Imamura; Atsushi Kyoto JPAANM Koike; ShiroAACI KyotoAACO JPAAGP Koike; Shiro Kyoto JP - An image reading apparatus includes two color line cameras and one monochrome line camera and captures a linear imaging area on printing paper. The imaging area is irradiated with illumination light by a line illumination part. When inspecting a printed image, a color image captured with the color line cameras and an original image are compared. An information element image such as a bar code is clipped from a monochrome image captured with the monochrome line camera, and target information indicated by an information element(s) is acquired. In the image reading apparatus, since the color image and the monochrome image are acquired from the same imaging area, it is possible to realize downsizing of the line illumination part and downsizing of the image reading apparatus. | 01-17-2013 |
