Summary:To minimize a deterioration in object detection accuracy while shortening a processing time without restrictions of a generation order of a distance image and a generation order of data.SOLUTION: An information processing device for recognizing an object existing in a still image or a moving image includes a distance image input unit for sequentially writing a partial area from which a distance image is acquired in a memory, a data processing unit for executing desired processing of a written unprocessed area each time an image for a prescribed amount is written in the distance image, and an information storage unit for executing storage of a result of the processing. The data processing part executes first processing for referring to information corresponding to the processing in a past frame from the information storage unit to execute the processing on the basis of information undergoing reference before generating necessary information in a target frame during the processing, and second processing for generating information in a target frame corresponding to the information in parallel with the first processing.SELECTED DRAWING: Figure 4 【課題】距離画像の生成順序やデータの生成順序の制約なしに処理時間を短縮しつつ、物体検出精度の低下を最小限に抑制する。【解決手段】静止画または動画像内に存在する物体を認識するための情報処理装置において、距離画像を取得した部分領域から順次メモリに書き込んでいく距離画像入力部と、前記距離画像に対し、所定量分の画像が書き込まれる度に、書き込まれた未処理領域に対して所望の処理を実行するデータ処理部と、前記処理の結果の保存を実行する情報保存部と、を備え、前記データ処理部は、前記処理の際に必要な情報が着目フレームで生成されるよりも前に、過去フレームにおける前記情報に対応する情報を前記情報保存部から参照し、参照した該情報に基づき前記処理を実行する第1処理と、前記第1処理と並行して前記情報に該当する着目フレームにおける情報を生成する第2処理と、を実行する。【選択図】図4
