  • Patent number: 10911739
    Abstract: The present invention provides a camera device capable of quickly processing image data while suppressing bus traffic. In the present invention, an image memory 50 is connected to a memory bus 70 and stores a right source image 220 and a left source image 210. A memory access management 40 is connected to the memory bus 70 and to an internal bus 80, reads the right source image 220 and the left source image 210 from the image memory 50 via the memory bus 70, and outputs the read right source image 220 and the left source image 210 to the internal bus 80. Processing unit A 30, processing unit B 31, and processing unit C 32 are connected to the internal bus 80 and process the image data output to the internal bus 80.

  • Patent number: 10154255
    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.
