A communication system includes circuitry. The circuitry receives an input of language information. The circuitry performs recognition on the input language information. The circuitry displays one or more images corresponding to the input language information on a display, based on a result of the recognition.

Communication system, display apparatus, and display control method

An image display apparatus includes a light source emitting light; an optical scanner scanning a predetermined scanning zone with light from the light source to render a display image; a light intensity detector detecting a light intensity of light from the light source; a memory storing relationships between control currents provided to the light source and light intensities; and one or more processors controlling, on the basis of the control current and light intensity relationships stored in the memory, a control current to display the display image with light from the light source. When the optical scanner scans an area outside the display image, the one or more processors detect by the light intensity detector a light intensity of light for the scanning, and update on the basis of the light intensity the relationships stored in the memory.

Image display apparatus, on-vehicle system, and image display method

An image display device includes a display unit configured to display a display image and to use a color information target value as a color information value of a display color, the display color being a color of the displayed image; and a first image correction unit configured, in a case where the color information value of the display color of the display image obtained by capturing the display image displayed by the display unit is different from the color information target value, to correct the color information value of the display color of the displayed image displayed by the display unit, so that the color information value of the display color of the display image obtained by capturing the display image displayed by the display unit becomes the color information target value.

Image display device and image display method

An HUD apparatus is configured to irradiate light for forming an image on a transmissive reflector provided in a movable body, and to display a virtual image in a display area to overlap the virtual image with scenery outside the movable body. A given distance range in the scenery from a reference point that is set in the movable body is included in the display area, and a difference between a first convergence angle to a target object (e.g., road surface) that is present in the given distance range and a second convergence angle to the virtual image displayed in the display area is at most one degree.

Display apparatus, movable body apparatus, producing method of the display apparatus, and display method

An information display apparatus emits an image forming light beam to a transmissive reflection member and makes a virtual image visible through the reflection member. The information display apparatus is configured to display the virtual image so that a difference between a convergence angle when viewing the virtual image through the reflection member and a convergence angle when viewing a real object through the reflection member is less than or equal to 1 degree.

Information display apparatus, information provision system, moving object device, information display method, and recording medium

An imaging device includes a three-axis acceleration detector, an inclination calculator to calculate an amount of inclination of the imaging device according to an output value of the acceleration detector, a determining element to determine whether or not the imaging device is dropping or receiving an impact according to the output value of the acceleration detector, a mode switching element to set the acceleration detector to be in either an electronic level mode or an impact detection mode by changing at least one of a measuring range and a sampling rate of the acceleration detector, and a storing element to store detected acceleration data in time series. When the determining element determines that the imaging device has dropped or received an impact in the impact detection mode, the storing element stores acceleration data detected at a time when the drop or impact has occurred.
