Summary:PROBLEM TO BE SOLVED: To acquire an image suitable for estimation of a pulse while suppressing increase of the data amount of the image by properly executing data compression processing of the image.SOLUTION: An image processing device 2 includes a data compression processor 16 for executing data compression processing based on inter-frame prediction on an input captured image, and an operation mode selection unit 17 capable of selecting either a first operation mode for normal imaging or a second operation mode for pulse estimation based on an instruction from a user. When the second operation mode is selected, the data compression processor 16 sets the interval of I pictures 35 constituting a compressed image generated by the data compression processing to an interval different from that when the first operation mode is selected.SELECTED DRAWING: Figure 2 【課題】画像のデータ圧縮処理を適切に実行することにより、画像のデータ量の増大を抑制しつつ脈拍の推定に好適な画像を取得する。【解決手段】画像処理装置２が、入力された撮像画像に対してフレーム間予測に基づくデータ圧縮処理を実行するデータ圧縮処理部１６と、ユーザからの指示に基づき、通常撮影用の第１動作モードおよび脈拍推定用の第２動作モードのいずれかを選択可能な動作モード選択部１７とを備え、データ圧縮処理部１６は、第２動作モードが選択された場合、データ圧縮処理により生成される圧縮画像を構成するＩピクチャ３５の間隔を、第１動作モードが選択された場合とは異なる間隔に設定する構成とする。【選択図】図２
