| 1. An abnormality detecting apparatus for an imaging apparatus that detects a presence of abnormalities in an imaging apparatus
mounted on a vehicle to capture vehicle surroundings, comprising:
a region setting device that sets a region including at least a road boundary portion in an image obtained by the imaging
apparatus;
a luminance variance value calculating device that calculates a luminance variance value using the luminance value acquired
from the image with respect to the region set by the region setting device; and
an abnormality detecting device that detects the presence of abnormalities in the imaging apparatus according to the luminance
variance value calculated by the luminance variance value calculating device;
a region excluding device that sets an excluded region outside the scope of execution of the process to calculate the luminance
variance value by the luminance variance value calculating device in the region set by the region setting device,
wherein the luminance variance value calculating device calculates the luminance variance value for the region other than
the excluded region set by the region excluding device among the region set by the region setting device.
