Title:
IN-VEHICLE-CAMERA IMAGE PROCESSING DEVICE
Document Type and Number:
WIPO Patent Application WO/2015/104915
Kind Code:
A1
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 (101) capable of selectively switching between a captured image and a test image and outputting the same; an image-processing unit (105) for subjecting a captured image outputted by the camera units (101) to image processing; and a fault diagnosis unit (106) for subjecting the camera units (101) to fault diagnosis, on the basis of the test image outputted by the camera units (101). In addition, the image-processing unit (105) 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 (105), the fault diagnosis unit (106) outputs, to the camera units (101), an image-selection-instruction signal for switching the image outputted by the camera units (101) from the captured image to the test image.
