  • Patent number: 9852159
    Abstract: An image recognition apparatus is provided which comprises a first extracting means for extracting, from every registration image previously registered, a set of registration partial images of a predetermined size, and a second extracting means for extracting, from an input new image, a set of new partial images of a predetermined size. The apparatus further comprises a discriminating means for discriminating an attribute of the new partial image based on a rule formed by dividing the set of the registration partial images extracted by the first extracting means, and a collecting means for deriving a final recognition result of the new image by collecting discrimination results by the discriminating means at the time when the new partial images as elements of the set of the new partial images are input.

  • Patent number: 9854387
    Abstract: A system which enables an image forming apparatus to give priority to executing a job sent from a mobile information terminal. The mobile information terminal sets an operating mode of the image forming apparatus. When a near-field wireless communication is started by the mobile information terminal coming close to the image forming apparatus, information on the set operating mode is sent to the image forming apparatus. The image forming apparatus provides operating mode shifting control based on the information on the operating mode sent from the mobile information terminal by the near-field wireless communication.

  • Patent number: 9854120
    Abstract: An optical scanning apparatus includes a deflector for scanningly deflecting a beam; a scanning lens for imaging the beam deflected by the deflector on a surface; a casing for a light source, the deflector and the lens; and an elastic member urging the lens toward the casing along an optical axis. The lens is provided with an abutment at a beam emergent side of the lens, the abutment abutting to the casing, and is provided with a limiting portion at a side opposite from the emergent side, the limiting portion limiting movement in the opposite direction. The elastic member and the limiting portion limits the movement of the lens in the direction opposite to the direction of the lens. When the lens contacts a positioning portion of the casing, a gap is provided between the elastic member and the limiting portion with respect to the direction.

  • Patent number: 9854177
    Abstract: An imaging apparatus combines images output from imaging units, and reduces such scenes that an image of a displaced subject is captured. The apparatus includes a driving unit that drives at least one imaging unit serving as a driving target among the imaging units, in predetermined driving modes, and a combining unit that combines pieces of image data acquired by the imaging units. The imaging units each include an imaging sensor in which photoelectric converters for converting light into an electrical signal are arranged in rows and columns. The driving unit divides a region for acquiring the image data into a plurality of regions each corresponding to a unit formed of one or more rows of the imaging sensor. The driving modes include a first driving mode in which the imaging unit serving as the driving target is sequentially switched for each exposure or readout of the unit.
