According to one example for capturing three-dimensional data of an object, illumination of an object is initiated, the object is scanned with a sensor, and a 3D representation of the object is created. Illumination of the object may comprise illumination of a surface of the object within a field of view of the sensor.

Methods and apparatuses are provided for a multi-mode display. In one embodiment, a multi-mode display comprises an array of light sensing and emitting units (LSEUs), a decoder configured to generate addresses for accessing one or more LSEUs in the array of LSEUs, and a controller configured to control the array of LSEUs using the addresses, where each LSEU in the array of LSEUs comprises a light sensing and emitting component (LSEC), an emitting circuit configured to generate light using the LSEC, and a sensing circuit configured to detect light using the LSEC.

An example method is performed at a device with a display and a biometric sensor. While the device is in a locked state, the method includes displaying a log-in user interface that is associated with logging in to a first and second user account. While displaying the log-in user interface, the method includes, receiving biometric information, and in response to receiving the biometric information: when the biometric information is consistent with biometric information for the first user account and the first user account does not have an active session, displaying a prompt to input a log-in credential for the first user account; and when the biometric information is consistent with biometric information for the second user account and the second user account does not have an active session on the device, displaying a prompt to input a log-in credential for the second user account.

A projection display unit (1) includes a projection optical system (10A), a polarization separation device (15), and a detection optical system (10B). The projection optical system includes an illuminator (11), a projection lens (16), and a light valve (12) that modulates illumination light supplied from the illuminator on the basis of an image signal, and outputs the modulated illumination light toward the projection lens. The polarization separation device (15) is disposed between the light valve and the projection lens. The polarization separation device separates entering light into a first polarized component and a second polarized component, and outputs the first polarized component and the second polarized component in respective directions that are different from each other. The detection optical system includes an imaging device (13) and a reduction optical system (14). The imaging device is disposed in a position that is optically conjugate with a position of the light valve. The reduction optical system is disposed between the imaging device and the polarization separation device. The imaging device receives, via the projection lens and the polarization separation device, light based on detection invisible light. A transmittance adjuster is provided between the polarization separation device and the imaging device. The transmittance adjuster adjusts transmittance of at least part of a bundle of passing light rays derived from the invisible light.

An adjustment method for adjusting the direction of infrared light projected so that infrared light to pass over a displayed image from a projection device that is rotatable with orthogonal first and second axes as axes of rotation, the method including: arranging the projection device such that the plane containing the first axis and a line perpendicular to the upper edge or lower edge of the displayed image is orthogonal to the plane in which the displayed image is displayed; displaying a first image representing a first target on the line; and rotating the projection device with the second axis as the axis of rotation such that the irradiation position of the infrared light upon an indicator in the first image, in which is displayed a captured image, coincides with the position of the first target on the first image.

Examples of a touch screen are disclosed herein. One example of the touch screen includes a plurality of light emitting diodes positioned adjacent a perimeter of a panel and a circuit electrically connected to the plurality of light emitting diodes to individually and sequentially illuminate the light emitting diodes. This example of the touch screen additionally includes a plurality of photodiodes positioned adjacent the perimeter of the panel so that each photodiode receives light from at least one of the light emitting diodes when illuminated by the circuit. Photodiodes that receive light from different light emitting diodes are electrically connected in parallel.

Disclosed herein are a mobile terminal and a method of controlling the same. Embodiments of the present invention provide a mobile terminal and a method of controlling the same, which are capable of simply controlling an object placed at the back of a transparent display by controlling the distance between the transparent display and the object in the state in which the object has been reflected in the transparent display.

An input method and a smart terminal device. After a processor in the smart terminal device determines, based on a first detection solution of a first infrared sensor, that a target object enters or leaves a first space range from a first plane, the processor starts or stops displaying a cursor based on distances measured by ultrasonic sensors; and after the processor determines, based on a second detection result of a second infrared sensor, that the target object enters or leaves a second space range from a second plane, the processor starts or stops performing a confirmation operation based on a location of the cursor.
