Abnormality detecting apparatus for imaging apparatus
First Claim
1. An abnormality detecting apparatus for an imaging apparatus having a plurality of imaging apparatuses, that detects a presence of abnormalities in said imaging apparatuses, said abnormality detecting apparatus comprising:
- a luminance variance value calculating device that calculates a luminance variance value of each image from the imaging apparatuses using the luminance value of each image obtained by the imaging apparatuses;
a variance value difference calculating device that calculates a difference between the luminance variance values of images from each of the imaging apparatuses; and
an abnormality detecting device that detects the presence of abnormalities in any of the imaging apparatuses in accordance with the luminance variance values calculated by the luminance variance value calculating device;
wherein said imaging apparatuses are mounted on a vehicle for capturing images of vehicle surroundings; and
wherein the abnormality detecting device detects the presence of abnormalities in any of the imaging apparatuses in accordance with the luminance variance value calculated by the luminance variance value calculating device and the difference calculated by the variance value difference calculating device.
