description To provide an image processing apparatus capable of preventing degradation of image quality, particularly in an edge part by improving the image quality on a piece of image data which is obtained by sensor scanning in which photo elements with different spectral characteristics are arranged in a specific pattern with a simple configuration.SOLUTION: The image processing apparatus has a filter processing part that is configured to average pixel values of at least the first direction type of photo elements on the image data (S203-S206) when performing processing on a piece of data which is generated by a reading unit that reads an original by scanning the original in the scanning direction by using at least one type of photo element out of multiple types of reading elements in which photo elements of multiple types with different spectral sensitivity characteristics are arranged periodically in the first direction (S201).SELECTED DRAWING: Figure 2 【課題】異なる分光特性のフォトエレメントが特定のパターンで配列されているセンサの走査による読み取りによって得られた画像データに対して、簡便な構成によって、画質を改善し、特にエッジ部の画質劣化を防ぐこと。【解決手段】画像処理装置のフィルタ処理部は、互いに分光感度特性が異なる複数の種類のフォトエレメントが第１方向に周期的に配列し且つ複数の種類の読取素子のうち少なくとも１種類のフォトエレメントを用いて走査方向に原稿を走査して原稿を読み取る読み取り部で生成Ｓ２０１された画像データの処理を行う場合、画像データに対して、少なくとも第１方向のフォトエレメントの種類分の画素値を平均化するＳ２０３〜Ｓ２０６を有する。【選択図】図２
