1. An outside environment recognition device comprising:
an information acquisition device that acquires outside environment information from an outside environment sensor and vehicle information from a vehicle sensor; and
an arithmetic operation device that recognizes a target based on the outside environment information and the vehicle information,
wherein the arithmetic operation device includes
a blind region edge detection unit that detects an edge of a blind region where the target is likely to appear, based on the outside environment information,
a traveling path estimation unit that estimates a future path of an own vehicle based on a traveling direction and a speed of the own vehicle included in the vehicle information,
a recognition region division unit that divides a region between the edge and the path into a first region to which first target recognition processing is applied and a second region to which second target recognition processing is applied, based on a contact possibility between the own vehicle and a virtual target appearing in the path from the edge, and
a target detection unit that detects a target appearing from the edge by applying the first target recognition processing in the first region, and detects the target appearing from the edge by applying the second target recognition processing in the second region, and
the first target recognition processing and the second target recognition processing have different recognition sensitivities.
