To provide a control device, a boiler, a monitoring image acquisition method of a boiler and a monitoring image acquisition program of a boiler capable of monitoring the situation inside a furnace, that is difficult to observe visually or by means of a visible light ray camera.SOLUTION: A control device 30 for monitoring a pulverized coal fired boiler 10 including a furnace 11 includes an image acquisition unit 31 for acquiring the moving image of a monitoring object unit in the furnace 11 captured by means of an infrared camera 40 as data, an image processing unit 32 for dividing the captured moving image data acquired by the image acquisition unit 31 into multiple regions for each frame, performing image processing base on the brilliance for each region, and acquiring the transmission region transmitted up to the monitoring object part from an integrated image obtained by integrating the brilliance of the image after image processing for a prescribed time, and a transmission image generation unit 33 for generating the transmission image at the monitoring object part on the basis of multiple transmission regions.SELECTED DRAWING: Figure 1 【課題】目視や可視光線カメラでは観察が困難な炉内の状況の監視を行うことのできる制御装置、ボイラ、ボイラの監視画像取得方法およびボイラの監視画像取得プログラムを提供することを目的とする。【解決手段】火炉１１を備えた微粉炭焚きボイラ１０の監視を行う制御装置３０であって、赤外線カメラ４０による火炉１１内部の監視対象部位の撮影動画をデータとして取得する画像取得部３１と、画像取得部３１が取得した撮影動画データをフレームごとに複数の領域に分割し、各領域ごとに輝度に基づく画像処理を行い、画像処理後の処理画像の輝度を所定時間積算して得られる積算画像から、監視対象部位まで透過した透過領域を取得する画像処理部３２と、複数の透過領域に基づき監視対象部位の透過画像を作成する透過画像作成部３３と、を備える。【選択図】図１
