In-vehicle-camera image processing device

Abstract

The present invention inexpensively executes fault diagnosis in real time without obstructing an original image-processing function even while driving. To this end, this in-vehicle-camera image processing device has: one or more camera units capable of selectively switching between a captured image and a test image and outputting the same; an image-processing unit for subjecting a captured image outputted by the camera units to image processing; and a fault diagnosis unit for subjecting the camera units to fault diagnosis, on the basis of the test image outputted by the camera units. In addition, the image-processing unit determines whether or not a fault diagnosis is possible on the basis of the image-processing results, and when fault diagnosis is determined to be possible, outputs diagnosis instruction information to the fault diagnosis unit. The in-vehicle-camera image processing device is characterized in that upon receiving input of the diagnosis instruction information from the image-processing unit, the fault diagnosis unit outputs, to the camera units, an image-selection-instruction signal for switching the image outputted by the camera units from the captured image to the test image.
