To generate an omnidirectional (spherical) image with a correct vertical direction in accordance with any tilt.SOLUTION: An image capturing apparatus includes: tilt detection means that detects a tilt with respect to a vertical direction; conversion data for converting a plane coordinate value into a spherical coordinate value; correction means that corrects the conversion data in accordance with the tilt; a plurality of pieces of image capturing means; coordinate conversion means that converts plane coordinate values of a plurality of pixels composing images captured by the image capturing means into spherical coordinate values on the basis of the conversion data corrected by the correction means; and combining means that combines the images including the plurality of pixels whose plane coordinate values are converted into the spherical coordinate values by the coordinate conversion means.SELECTED DRAWING: Figure 3 【課題】任意の傾きに対応して、鉛直方向の正しい全方位（全天球）画像を生成する。【解決手段】鉛直方向に対する傾きを検出する傾き検出手段と、平面座標値を球面座標値に変換する変換データと、傾きに応じて、変換データを補正する補正手段と、複数の撮像手段と、撮像手段により撮像された画像を構成する複数の画素の平面座標値を、補正手段により補正された変換データに基づいて球面座標値に変換する座標変換手段と、座標変換手段により球面座標値に変換された複数の画素を含む画像を組み合わせる組み合わせ手段と、を含む。【選択図】図３
