To provide a technique for synthesizing a bird's-eye view image that hardly lets drivers feel strange.SOLUTION: An image creation device 20 includes a bird's-eye view creation unit configured to perform bird's-eye view conversion on the basis of a captured image acquired by an image acquisition unit. The bird's-eye view creation unit includes a first creation unit configured to create a stereoscopic bird's-eye view image by projecting a three-dimensional object region onto a three-dimensional projection surface that represents a virtual surface that has a three-dimensional curvature and is inclined upward toward a distant place from an imaging position of an imaging device (S270). The bird's-eye view creation unit includes a second creation unit configured to create a planar bird's-eye view image that is an image obtained by bird's-eye view conversion of a road surface area by projecting the road surface area onto a road surface projection surface representing a road surface on which a vehicle exists in a real space (S130). The bird's-eye view creation unit includes an image synthesis unit configured to synthesize the stereoscopic bird's-eye view image created by the first creation unit and the planar bird's-eye view image created by the second creation unit (S290).SELECTED DRAWING: Figure 1 【課題】ドライバが違和感を覚えにくい鳥瞰画像を合成する技術を提供する。【解決手段】画像作成装置２０が備える鳥瞰作成部は、画像取得部により取得された撮像画像に基づいて、鳥瞰変換を行う。鳥瞰作成部が備える第一作成部は、Ｓ２７０で立体曲率を有し、かつ、撮像装置の撮像位置から遠方に向かって上り方向に傾斜する仮想の面を表した立体投影面に立体物領域を投影することにより立体鳥瞰画像を作成する。鳥瞰作成部が備える第二作成部はＳ１３０で、実空間上における車両が存在する路面を表した路面投影面に路面領域を投影することにより、路面領域を鳥瞰変換した画像である平面鳥瞰画像を作成する。鳥瞰作成部が備える画像合成部は、Ｓ２９０で第一作成部により作成された立体鳥瞰画像と第二作成部により作成された平面鳥瞰画像とを合成する。【選択図】図１
