Summary:To solve the issue that the rate of writing and reading becomes significantly lower when there are many commands waiting to be processed in a queue of a storage device in a situation that it is necessary to wait for the order of processing with a command of writing and reading a material other than image data in the queue of the storage device as well when a command is sent without a queue of an OS.SOLUTION: The present invention relates to an information processor including: non-volatile storage means for storing image data; control means for generating a command that the storage means is to execute; and holding means for holding the command generated by the control means. The storage means acquires a command held by the holding means. The holding means includes: first holding means for holding a first type of command related to the image data; and second holding means for holding a second type of command unrelated to the image data.SELECTED DRAWING: Figure 7 【課題】 OSのキューを介さずにコマンドを送信した場合でも、ストレージ装置のキューにおいて画像データ以外を読み書きするコマンドと一緒に処理の順番を待つことになる。ストレージ装置のキューに格納されている処理待ちのコマンドが多い場合には読み書き速度が大きく低下する。【解決手段】 本発明は、画像データを記憶可能な不揮発性の記憶手段と、前記記憶手段に実行させるコマンドを生成する制御手段と、前記制御手段によって生成されたコマンドを保持する保持手段を有する情報処理装置であって、前記記憶手段は、前記保持手段によって保持されたコマンドを取得し、前記保持手段は、画像データに関する第1種類のコマンドを保持する第1保持手段と、画像データに関しない第2種類のコマンドを保持する第2保持手段と、を含むことを特徴とする。【選択図】 図7
