PROBLEM TO BE SOLVED: To provide an interpolation image generation device that makes it possible to generate an interpolation image that enhances prediction accuracy at an arbitrary time earlier than a photograph-taking time for an affected part of a subject which is not photographed in an image taken at the photograph-taking time earlier than a certain photograph-taking time.SOLUTION: An interpolation image generation device includes: a generation time position specification unit (14) that specifies a generation time of an affected part and a generation position of the affected part on the basis of changes in size and shape between an affected part photographed on a first image obtained by taking a photograph of a subject at a first photograph-taking time and an affected part photographed on a second image obtained by taking a photograph of the subject at a second photograph-taking time after the first photograph-taking time, and a difference between the first photograph-taking time and the second photograph-taking time; and an interpolation image generation unit (15) that receives a specification time earlier than the first photograph-taking time, and generates an image of the affected part at the specification time from the generation time, the generation position, the first photograph-taking time and the image of the affected part on the first image.SELECTED DRAWING: Figure 3 【課題】ある撮影時刻よりも前の撮影時刻の画像には写っていない被写体の患部について、その撮影時刻よりも前の任意の時刻での予測精度を向上した補間画像を生成可能な補間画像生成装置を提供する。【解決手段】補間画像生成装置は、被写体を第１の撮影時刻に撮影して得られた第１の画像上に写っている患部と、第１の撮影時刻よりも後の第２の撮影時刻に被写体を撮影して得られた第２の画像上の患部の、大きさと形の変化と、第１の撮影時刻と第２の撮影時刻の差とに基づいて、患部の発生時刻及び患部の発生位置を特定する発生時刻位置特定部（１４）と、発生時刻より後、第１の撮影時刻よりも前の指定時刻を受け付け、その指定時刻の患部の画像を、発生時刻及び発生位置と、第１の撮影時刻及び第１の画像上の患部の画像から生成する補間画像生成部（１５）とを有する。【選択図】図３
