To provide a signal processor capable of correctly finding a relative relation between a non-common detection object and another detection object that is common after fusion, even when detection objects are different from each other according to a plurality of sensors.SOLUTION: A first positional relation (for example, inside/outside one's own vehicle lane) between a first object (for example, a front vehicle) and a second object (for example, a white line) that are recognized based on an image imaged by an imaging apparatus 301 is stored, and a position of the first object is determined from information of the first object recognized based on information obtained from a sensor different from the imaging apparatus 301, and information of the first object recognized based on the image imaged by the imaging apparatus 301. A second positional relation (for example, inside/outside one's own vehicle lane) between the determined first object and the second object recognized based on the image imaged by the imaging apparatus 301 is determined. A final positional relation between the first object and the second object is determined by comparing the first positional relation with the second positional relation.SELECTED DRAWING: Figure 3 【課題】複数のセンサにおいて検出対象物が異なる場合であっても、非共通の検出対象物とフュージョン後に共通する検出対象物との相対関係を正しく求めることができる信号処理装置を提供する。【解決手段】撮像装置３０１で撮像された画像に基づき認識された第一の物体（例えば前方車両）と第二の物体（例えば白線）との間の第一の位置関係（例えば自車レーンの内外）を記憶し、前記撮像装置３０１とは異なるセンサから得られた情報に基づき認識された前記第一の物体の情報と、前記撮像装置３０１で撮像された画像に基づき認識された前記第一の物体の情報とから、前記第一の物体の位置を求め、求められた前記第一の物体と、前記撮像装置３０１で撮像された画像に基づき認識された前記第二の物体との間の第二の位置関係（例えば自車レーンの内外）を求め、前記第一の位置関係と前記第二の位置関係を比較して、前記第一の物体と前記第二の物体の最終的な位置関係を決定する。【選択図】図３
