To make it possible to achieve both improved video visibility and higher resolution.SOLUTION: The image generation apparatus includes: an input unit for inputting an input image signal including a plurality of frames; an acquisition unit for acquiring information related to an amount of movement between frames of the input image signal; and a generation unit for generating a display image signal on the basis of the input image signal. The generation unit is configured to: perform a first generation process for generating a display image signal on the basis of a predetermined number of, that is, two or more processing frames obtained by thinning out a target frame of the input image signal at mutually different phases when an amount of movement is smaller than a threshold; and perform a second generation process for generating a display image signal on the basis of the processing frames obtained by thinning out the target frames of the input image signal when an amount of motion is greater than or equal to the threshold.SELECTED DRAWING: Figure 1 【課題】動画視認性向上と高解像度化の両立をすることを可能にする。【解決手段】画像生成装置は、複数のフレームを含む入力画像信号を入力する入力部と、入力画像信号のフレーム間の動き量に関連する情報を取得する取得部と、入力画像信号に基づいて表示画像信号を生成する生成部と、を備える。生成部は、動き量が閾値より小さい場合に、入力画像信号の対象フレームを互いに異なる位相で間引いて得られた２以上の所定数の処理フレームに基づいて表示画像信号を生成する第１の生成処理を実行し、動き量が閾値以上の場合に、入力画像信号の対象フレームを間引いて得られた処理フレームに基づいて表示画像信号を生成する第２の生成処理を実行する。【選択図】 図１
