Abstract: An image acquisition unit acquires a first image corresponding to a rear view from a vehicle, a second image corresponding to a left view from the vehicle in a rearward direction, and a third image corresponding to a right view from the vehicle in the rearward direction. An image processor generates, when a speed is greater than or equal to a first threshold, an image by superimposing a fourth image on the second image and the third image, the fourth image resulting from preventing a first predetermined range corresponding to a lower portion of the first image from being displayed. The image processor generates, when the speed is less than a second threshold, an image by superimposing a fifth image on the second image and the third image, the fifth image resulting from preventing a second predetermined range corresponding to both end portions of the first image from being displayed.

Abstract: An imaging apparatus state monitoring device monitors an imaging state of an imaging unit. The imaging apparatus state monitoring device has an image acquisition unit, a blinking determination unit, and an abnormality processor. The image acquisition unit acquires a captured image captured by the imaging unit of which an imaging range includes an image of a blinking and light-emitting unit repeatedly blinking The blinking determination unit determines whether a change corresponding to blinking is included in the captured image. When blinking determination unit determines that no change according to blinking is included in the captured image, the abnormality processor executes abort processing.
