摘要： A display apparatus that includes a first imaging unit that images a user, a first distance detector that identifies an eye of the user and measure a first distance that is a distance from the identified eye to the first imaging unit, a second imaging unit that images an object, a second distance detector that measures a second distance that is a distance from the second imaging unit to the object, an image processor that processes the images, and a display unit, the image processor calculating a display imaging range, extracting the calculated display imaging range from the image imaged by the second imaging unit, and causing the display unit to display it, and the display imaging range being such a range that the object displayed and an external scenery not interrupted by the display unit seen from a viewpoint of the user have the same size.

摘要： The portable device is provided with a photograph unit to acquire, at a first time interval, images with a super wide angle of which a maximum value reaches all peripheral directions around the portable device; a traveling direction calculation unit to calculate a traveling direction of the portable device at a second time interval; an image segmentation unit to segment, as a traveling direction image, an image of a predetermined range where the traveling direction is positioned at a center thereof, from a latest acquired image every time the traveling direction calculation unit calculates the traveling direction; and a display control unit to display the traveling direction image on a predetermined traveling direction display region of a display of the portable device. The display control unit displays a video image designated by a user on a first display region, which is different from the traveling direction display region.

摘要： A speech recognition device includes a sound input section, a sound output section, a communication control section that performs data transmission and reception with at least one of other recognition devices, a conversation-mode executing section that transmits sound data input to each of the other recognition devices and outputs sound data received from each of the other recognition devices, a speech recognition section that converts the sound input into text data, a hot word detecting section that detects a conversation activation hot word from the text data to activate the conversation-mode executing section, and a command transmitting section that transmits a control command to each of the other recognition devices. If the hot word detecting section detects the conversation activation hot word, the command transmitting section transmits the control command to activate a conversation-mode executing section provided in each of the other recognition devices.

摘要： An imaging device and an authentication controller are provided. The imaging device includes a modulator that includes a first pattern and that modulates light intensity with the first pattern, an image sensor that converts a light beam transmitted through the modulator into imaging data and outputs the imaging data, an image processing unit that performs, to the imaging data, a reconstruction process in which an image of the subject is reconstructed based on the cross-correlation operation between the imaging data and the pattern data having a second pattern and acquires an image, and a distance measurement unit that repeats the reconstruction process to the imaging data while changing a focus distance and acquires a focus distance having a highest contrast in a measurement region as a distance. The authentication controller performs image authentication and distance authentication using image data and distance data acquired by the imaging device.
