PROBLEM TO BE SOLVED: To easily identify a detection target when searching the detection target by use of photographing means.SOLUTION: An aircraft 1 searching a prescribed detection target by use of an optical camera 14 comprises: a display 15 which displays an image photographed by the optical camera 14; and a controller 18. The controller 18 extracts a region of interest WA including an identification object T estimated as of the detection target from a display image on the display 15, calculates representative values Pin, Pout of the image feature amount at both the inner and outer sides of the region of interest WA in the display image and representative values Pi of the image feature amount in a plurality of small regions SA made by dividing the region of interest WA, and extracts the small region as an object existence region TA where the identification object T exists when the representative value Pi of the image feature amount in the plurality of small regions is close to the representative value Pin of the image feature amount at the inner side of the region of interest WA in comparison with the representative value Pout of the image feature amount at the outer side of the region of interest WA.SELECTED DRAWING: Figure 2
【課題】撮影手段を用いた探知目標の捜索において、探知目標の識別を容易に行えるようにする。【解決手段】航空機1は、光学カメラ14を用いて所定の探知目標を捜索するものであり、光学カメラ14が撮影した画像を表示するディスプレイ15と、制御部18とを備える。制御部18は、ディスプレイ15に表示された表示画像から、探知目標と思われる識別対象Tを含む注視領域WAを抽出し、表示画像のうちの注視領域WAの内外それぞれにおける画像特徴量の代表値Pin,Poutと、注視領域WAを分割した複数の小領域SAそれぞれにおける画像特徴量の代表値Piとを算出し、複数の小領域SAのうち、その画像特徴量の代表値Piが注視領域WA外の画像特徴量の代表値Poutよりも注視領域WA内の画像特徴量の代表値Pinに近いものを、識別対象Tが存在する対象存在領域TAとして抽出する。【選択図】図2
