  • Publication number: 20120099763
    Abstract: An image recognition part of an image recognition apparatus recognizes an object based on a target area in an outside-vehicle image obtained by a camera installed in a vehicle. A position identifying part identifies an optical axis position of the camera relative to the vehicle based on the outside-vehicle image, and an area changing part changes a position of the target area in the outside-vehicle image according to the optical axis position of the camera. Therefore, it is possible to recognize an object properly based on the target area in the outside-vehicle image even though the optical axis position of the camera is displaced.

  • Patent number: 7475045
    Abstract: In order to cause effective function when a system adopting a conventional settlement card is shifted to a system adopting a settlement card of IC card type and to enable a significant contribution to proliferation of the settlement card of IC card type, when a person who has input authentication data is authenticated as a user of a card by an authentication section, transaction data read by a magnetic stripe reader and transaction authentication data read by a memory reader are transmitted to a host server from transaction terminal equipment. The host server conducts a transaction through use of the transaction data and the transaction authentication data, both being output from the transaction terminal equipment. When the transaction is conducted, a memory writer writes data into memory of the card or rewrites data recorded in the memory.

  • Publication number: 20080187234
    Abstract: In a device for combining a plurality of images having a same photograph range, a position shift between the images having the same photograph range is detected, and the position shift of the images is corrected, and after the position shift is corrected, similarity of the respective portions between the images is evaluated, and the image combining method is changed according to the similarity evaluation. Therefore it is possible to create an image having no position shift due to the shaking of a camera and object blurring due to the movement of the object. Moreover, whether the images are combined or not is determined according to the similarity, hence the processing load is reduced and an image having no object blurring can be created.
