1. A method of determining normality of an imaging direction executed by a computer, the method comprising:
- acquiring captured images from an imaging device mounted on a vehicle; and
determining the normality of the imaging direction of the imaging device in accordance with whether an appearance pattern of a combination of a portion in which a variation is detected and a portion in which a variation is not detected among the acquired captured images corresponds to a predetermined pattern.

Abstract
An image processing apparatus includes an acquiring unit, and determining unit. The acquiring unit acquires captured images from an imaging device mounted on a vehicle. The determining unit determines the normality of the imaging direction of the imaging device in accordance with whether an appearance pattern of a combination of a portion in which a variation is detected and a portion in which a variation is not detected among the acquired captured images corresponds to a predetermined pattern.

3. A computer-readable recording medium storing a program that causes a computer to execute a process comprising:
-
acquiring, from an imaging device attached to a vehicle, image data in each of a plurality of frames in each of which a reference direction is defined; calculating, for each area of the image data in the reference direction, an index related to an amount of a difference between the frames of the image data; and evaluating an attachment state of the imaging device on the basis of distribution of the indices related to the amount of the difference in the reference direction. - View Dependent Claims (4, 5, 6)
