Zusammenfassung:	To provide an image processing method for reducing a likelihood of occurrence of a problem caused by a difference in brightness of a cross-sectional image according to a type of a tire.SOLUTION: A method for processing a cross-sectional image of a pneumatic tire of an embodiment includes: a tire image extraction step of extracting a rubber part in a tire cross-sectional image from an entire image, the entire image including the tire cross-sectional image and a rim cross-sectional image; an average luminance calculation step of determining an average luminance of the rubber part; and a luminance adjustment step of performing processing of bringing luminance of the tire cross-sectional image closer to reference luminance by using the average luminance.SELECTED DRAWING: Figure 1 【課題】タイヤの種類によって断面画像の輝度が異なることによる不具合が生じにくくなる画像処理方法を提供する。【解決手段】実施形態の空気入りタイヤは、タイヤの断面画像の処理方法において、全体画像の中にタイヤ断面画像及びリム断面画像が含まれ、前記全体画像から前記タイヤ断面画像のゴム製部分を抽出するタイヤ画像抽出ステップと、前記ゴム製部分の平均輝度を求める平均輝度算出ステップと、前記平均輝度を使用して、前記タイヤ断面画像の輝度を基準輝度に近づける処理を行う輝度調整ステップとを含む。【選択図】図１
