To suitably perform processing of converting a spectral configuration of an image photographing the ground where plants grow.SOLUTION: An information processing device comprises: an acquisition unit for acquiring a first image having a first spectral configuration, the image in which the ground is photographed; and a conversion unit for generating a second image in a second spectral configuration different from the first spectral configuration by performing conversion processing for each pixel in respect to the first image, wherein the conversion processing includes: first processing of converting pixel values in the first spectral configuration into pixel values in a third spectral configuration encompassing the first spectral configuration and the second spectral configuration; second processing of modifying the pixel values in the third spectral configuration as a result of the first processing in accordance with characteristic differences between the first image and the second image; and third processing of extracting pixel values in the second spectral configuration from the pixel values in the third spectral configuration modified by the second processing. The same includes a learning unit for adjusting the contents of the first processing and the second processing by utilizing pseudo data generated by using a plant crop community radiative transfer simulation model.SELECTED DRAWING: Figure 1 【課題】植物が生えている地面を撮像した画像のスペクトル構成を変換する処理を好適に行う。【解決手段】地面を撮像した第１スペクトル構成を有する第１画像を取得する取得部と、第１画像に対して画素ごとに変換処理を行うことで、第１スペクトル構成と異なる第２スペクトル構成の第２画像を生成する変換部とを備え、変換処理は、第１スペクトル構成の画素値を、第１スペクトル構成および第２スペクトル構成を包含する第３スペクトル構成の画素値に変換する第１処理と、第１処理の結果である第３スペクトル構成の画素値を、第１画像と第２画像の特性差に応じて修正する第２処理と、第２処理によって修正された第３スペクトル構成の画素値から第２スペクトル構成の画素値を取り出す第３処理と、を含み、第１処理および第２処理の内容を、植物の作物群落放射伝達シミュレーションモデルを用いて生成した疑似データを利用して調整する学習部を備える情報処理装置。【選択図】図１
