PROBLEM TO BE SOLVED: To appropriately correct lines included in an image, and output a high-quality image.SOLUTION: An image processing apparatus includes: input means for accepting input data; detecting means for detecting line information from the input data, line information indicating color information about a line included in the input data, color information about the background of the line, and the width of the line; and converting means for converting the line information so as to fix a contrast integrated value of the line determined by the color information about the background, the color information about the line, and the width of the line and to maximize the absolute value of difference between the color information about the background and the color information about the line. 【課題】 画像に含まれる線を適切に補正し、高画質な画像を出力する。【解決手段】 入力データを入力する入力手段と、前記入力データから、前記入力データに含まれる線の色情報、前記線の背景の色情報、前記線の幅を示す線情報を検出する検出手段と、前記背景の色情報と前記線の色情報と前記線の幅によって決まる線とによって決まるコントラスト積算値を一定とし、前記背景の色情報と前記線の色情報との差分の絶対値が最大になるように、前記線情報を変換する変換手段と、を有することを特徴とする画像処理装置。【選択図】 図１
