PROBLEM TO BE SOLVED: To provide a processing device capable of outputting and controlling related to the reliability of distance to a subject obtained from an image.SOLUTION: According to an embodiment, a processing device includes an acquisition unit, a distance calculation unit, and a reliability calculation unit. The acquisition unit acquires a first image of a subject including a blur of a shape indicated by a symmetrical first blur function and a second image of the subject including a blur of the shape indicated by an asymmetrical second blur function. The distance calculation unit calculates distance to the subject on the basis of correlation between the first blur function and the second blur function. The reliability calculation unit calculates the reliability of the distance on the basis of a level of the correlation.SELECTED DRAWING: Figure 5

    【課題】画像から得た被写体までの距離の信頼度に関する出力や制御を行うことができる処理装置を提供する。【解決手段】実施形態によれば、処理装置は、取得部と、距離算出部と、信頼度算出部と、を具備する。前記取得部は、対称な第1のぼけ関数で示される形状のぼけを含む被写体の第1の画像と、非対称な第2のぼけ関数で示される形状のぼけを含む前記被写体の第2の画像とを取得する。前記距離算出部は、前記第1のぼけ関数と前記第2のぼけ関数との相関に基づき、前記被写体までの距離を算出する。前記信頼度算出部は、前記相関の度合いに基づき前記距離の信頼度を算出する。【選択図】図5
