PROBLEM TO BE SOLVED: To provide systems and methods for combining a visible light image 400 and an infrared image 408.SOLUTION: The visible light image is processed 402 to determine edge factor values for a plurality of visible light pixels corresponding to the strength of an edge at that location. The edge factor values are determined using features from the visible light image data and an edge gain input, but adjustable by a user. The edge factor values are combined with an edge midscale value 404 to create a set of modified visible light image data 406 including pixels emphasized based on the strength of the edge in the visible light image. The modified visible light image data is combined with the infrared image data to create combined image data 410 having contribution from the infrared image data and the edge factor values from the visible light image data.SELECTED DRAWING: Figure 4 【課題】可視光画像400及び赤外線画像408を組合せるシステム及び方法を提供する。【解決手段】可視光画像を処理して402、その場所の輪郭の強さに対応する複数の可視光ピクセル用の輪郭係数値を決定する。輪郭係数値は、可視光画像データ及び輪郭利得入力の特性を用いて決定するが、ユーザが調整可能である。輪郭係数値を輪郭ミッドスケール値404と組合せて、可視光画像の輪郭の強度に基づき強調されたピクセルを含む１組の変更済み可視光画像データ406を生成する。変更済み可視光画像データを赤外線画像データと組合せて、赤外線画像データの寄与及び可視光画像データの輪郭係数値を有する混合済み画像データ410を生成する。【選択図】図４
