To reduce an influence of a systematic error in operation of sub-pixel precision in distance measurement using two images including parallax.SOLUTION: An imaging apparatus is an imaging apparatus for acquiring a pair of images having two images including parallax, and measuring distance to an object on the basis of the parallax searched from the pair of images and a baseline length for causing the parallax, and acquires the plurality of pairs of images having the different parallax according to the different baseline length, and an integer multiple of the quotient obtained by dividing the longer baseline length from among the different baseline lengths by the shorter baseline length has an infinite decimal.SELECTED DRAWING: Figure 1 【課題】視差が含まれる２つの画像を用いた距離測定において、サブピクセル精度の演算における系統的な誤差の影響を低減することを課題とする。【解決手段】開示の技術の一態様に係る撮像装置は、視差が含まれる２つの画像を有する画像ペアを取得し、前記画像ペアから探索した前記視差と、前記視差を生じさせる基線長と、に基づき被写体との距離を測定する撮像装置であって、異なる前記基線長に応じ、前記視差の異なる複数の前記画像ペアを取得し、異なる前記基線長のうち長い方の前記基線長を、短い方の前記基線長で除した商の整数倍は、無限小数を有することを特徴とする。【選択図】図１
