Summary: | To achieve a method in which even if a difference of brightness values between ink and base color of a recording medium is small, a pattern to be recorded by ink can be detected with good accuracy and a recording position can be adjusted.SOLUTION: An inkjet recording device comprises: correcting means that corrects a signal corresponding to a first color using first shading data on the basis of a white reference and corrects a signal corresponding to a second color using second shading data on the basis of a base color of a recording medium and a color of an area formed using prescribed ink, with respect to an image of a chart; specifying means that specifies areas formed using a plurality of ink respectively in the image of the chart, using the signal corrected by the correcting means; and calculating means that calculates positional shift amounts of a recording head on the basis of positions of the areas specified by the specifying means.SELECTED DRAWING: Figure 15
【課題】インクと記録媒体の下地色との輝度値差が小さい場合でも、インクにて記録されるパターンの検出を精度よく行い、記録位置調整が可能な方法を実現する。【解決手段】インクジェット記録装置であって、前記チャートの画像に対し、第1の色に対応する信号を、白基準に基づく第1のシェーディングデータを用いて補正し、第2の色に対応する信号を記録媒体の下地の色及び所定のインクにて形成された領域の色に基づく第2のシェーディングデータを用いて補正する補正手段と、前記補正手段にて補正された信号を用いて、前記チャートの画像における前記複数のインクそれぞれにて形成された領域を特定する特定手段と、前記特定手段にて特定した領域の位置に基づいて、前記記録ヘッドの位置ずれ量を算出する算出手段とを備える。【選択図】 図15 |
