Claim Text:
1. A vehicle-mounted environment recognition device comprising: an imaging unit that acquires an image taken by an imaging device; an image self-diagnosis unit that diagnoses a lens contamination state of the imaging device and an ambient environment with respect to the image acquired by the imaging unit; an application execution unit that executes an application selected from a predetermined application group comprising lane recognition, vehicle detection, and pedestrian detection; and a fail determination unit that determines, based on a result of comparison of a result of diagnosis by the image self-diagnosis unit relating to the lens contamination state and the ambient environment with a threshold value set in advance for each application, one or more from the group consisting of: whether the application executed by the application execution unit is to be transitioned to a suppression mode with an adjusted processing parameter for erroneous detection suppression, whether lens contamination removal control is to be performed, and whether a fail determination is to be made for the application, wherein the image self-diagnosis unit sets a processing region for each application executed by the application execution unit, divides the processing region, diagnoses the lens contaminated state for each divided region, and outputs the diagnosis result.
