PROBLEM TO BE SOLVED: To provide an image processing apparatus configured to prevent moire, an article processing apparatus, and an image processing method.SOLUTION: An image processing apparatus for acquiring an image from an object includes a plurality of light sources, a line sensor, and a control section. The light sources irradiate an object with light of different colors. The line sensor outputs luminance data for one line, which is obtained by photoelectrically converting reflected light of the light irradiated by the light sources on the object. The control section acquires a random number, and acquires luminance data for one line to be output by the line sensor, on the basis of the acquired random number, while one light source selected from the above light sources emits light.SELECTED DRAWING: Figure 2 【課題】モアレの発生を防止する画像処理装置、物品処理装置、及び、画像処理方法を提供する。【解決手段】実施形態によれば、対象物から画像を取得する画像処理装置は、複数個の光源と、ラインセンサと、制御部と、を備える。複数個の光源は、対象物に対して異なる色の光を照射する。ラインセンサは、前記光源が前記対象物に対して照射した光の反射光を光電変換した１ライン分の輝度データを出力する。制御部は、乱数を取得し、取得した乱数に基づいて前記複数個の光源から選択する１つの光源を発光させた状態で、前記ラインセンサが出力する１ライン分の輝度データを取得する。【選択図】図２
