  • Patent number: 9964958
    Abstract: A vehicle control system determines a travel priority of a vehicle based on a travel condition of the vehicle. In response to detection of an oncoming vehicle ahead of the vehicle along a single guide path, the system compares between the travel priority of the vehicle, and a travel priority of the oncoming vehicle, and selects one of the vehicle and the oncoming vehicle as a vehicle to change a traveling route, to allow the unselected vehicle to continue traveling along the single guide path.

  • Patent number: 8422811
    Abstract: Characteristics of image data from a reading unit are unified for storage. The state of the image data is recognized and retained as auxiliary information. The auxiliary information is checked, and an image skew and the like are detected according to a target output format to perform a correction process. At that time, an optimum image processing path is selected for processing according to the state of implementation of hardware and software. A simple process can be performed at an image processing apparatus, while a complex process is performed at a network-connected PC. Since a unit configuration can be selected according to the purpose of image processing, processing can be performed with a simple configuration at high speed.

  • Patent number: 8294954
    Abstract: An image processing controlling unit calculates an image processing parameter to reduce an image quality difference between image data read by a first reading unit and a second reading unit depending on a reading characteristic of a reading unit indicated by attached information (reading-unit information) received together with the calculating request and a writing characteristic of a printer. The calculated image processing parameter is stored in a memory. Next, when printing the image data, a middleware unit causes a printer to print the image data based on the image processing parameter held in the memory.
