Abstract: A head-mounted display comprises: a wearing body; a display; a communication module configured to perform communication connection with a mobile information terminal; a field of view (FOV) sensor configured to output status data used for determining whether the mobile information terminal is included in a user's FOV through the wearing body; and a controller connected to each of the display, the communication module, and the FOV detection sensor. The controller determines whether the mobile information terminal is included in the user's FOV based on the status data, and performs display control with respect to the display so as to display an application screen of the mobile information terminal on the display when determining that the mobile information terminal is not included in the FOV, and not to display the application screen on the display when determining that the mobile information terminal is included in the FOV.

Abstract: Provided is an imaging system capable of stereo-photographing with both of visible and infrared images, and improving color reproducibility in visible-light-photographing. The imaging system includes two imaging sensors, and two DBPFs that have transmittance characteristics in a visible light band and a second wavelength band, are respectively provided correspondingly to the two imaging sensors, and serve as optical filters. The imaging system has: at least four kinds of filters, which have mutual different spectral transmission characteristics corresponding to wavelengths in the visible light band and whose transmissions in a second wavelength band approximate each other; and two color filters provided so as respectively correspond to the two imaging sensors. The imaging system measures a distance to a target based on two visible or infrared image signals.

Abstract: The occlusion is faithfully expressed even in the binocular vision in the AR display by a head mounted display apparatus or the like. A head mounted display apparatus 10 includes a lens 12, a lens 13, a camera 14, a camera 15, and a control processor 16. A CG image for a right eye is displayed on the lens 12. A CG image for a left eye is displayed on the lens 13. The camera 14 captures an image for the right eye. The camera 15 captures an image for the left eye. The control processor 16 generates the CG image for the right eye in which occlusion at the time of seeing by the right eye is expressed and the CG image for the left eye in which occlusion at the time of seeing by the left eye is expressed, based on the images captured by the cameras 14 and 15 and projects the generated CG image for the right eye and CG image for the left eye onto the lenses 12 and 13. A center of a lens of the camera 14 is provided at the same position as a center of the lens 12. A center of a lens of the camera 15 is provided at the same position as a center of the lens 13.

Abstract: Provided is a camera apparatus capable of measuring a distance to a subject omnidirectionally while capturing an image of the subject omnidirectionally, and storing data of the image and the distance in correspondence therebetween. The camera apparatus includes two camera devices installed at positions that enable omnidirectional imaging; and two distance measurement devices installed at positions that enable omnidirectional distance measurement. Image data of each of pixel positions captured by the camera devices and distance data of each of the pixel positions measured by the distance measurement devices are stored in a memory in association with the pixel positions. The two camera devices are installed on surfaces that face each other with respect to a principal surface of the camera apparatus, and the two distance measurement devices are installed on surfaces that face each other with respect to a surface orthogonal to the principal surface of the camera apparatus.

Abstract: The MR display device includes a controller and a display unit. The controller recognizes a reality object from a reality video imaged by a camera and links a predetermined virtual object to the reality object based on an operation of an experiencing person. The display unit displays a video of the linked virtual object. The controller acquires a recognition result of a reality object generated by the other MR display device and data of the linked virtual object, via a communication unit, synthesizes the acquired data and the own data, and displays a video obtained by the synthesis on the display unit. In addition, the controller allows an edit of the virtual object linked to the reality object on the video displayed on the display unit, based on an operation of the experiencing person.
