This application provides an image processing method and apparatus that can: acquire a target object through each narrow-band filter to obtain a narrow-band channel image including the target object; and fuse multiple narrow-band channel images in one-to-one correspondence with the multiple narrow-band filters to obtain a color image including a contour of the target object.

A head-mounted device may have a head-mounted support structure. Rear-facing displays may present images to eye boxes at the rear of the head-mounted support structure. A forward-facing publicly viewable display may be supported on a front side of the head-mounted support structure facing away from the rear-facing displays. The forward-facing display may have pixels that form an active area in which images are displayed and may have a ring-shaped inactive border area that surrounds the pixels. The active area may have a curved peripheral edge with a nose bridge recess. The inactive border area may have a periphery that runs parallel to the peripheral edge of the active area. The forward-facing display may have a cover layer with a developable surface overlapping the active area and a ring-shaped surface of compound curvature that overlaps the inactive area. Optical components may operate through the cover layer in the inactive area.

A process and an image evaluation system are provided with a mobile sensor arrangement, including a camera (IR), a motion sensor (IMU), and a receiver (Komm), that is moved through a spatial area. The camera generates an image sequence. The motion sensor generates an orientation signal with camera viewing direction in a predefined three-dimensional coordinate system when generating an image. A signal processing unit (Sv) checks whether the receiver is receiving a signal from a transmitter (UWB.1, UWB.2, UWB.3) of a transmitter group. If the receiver receives a signal, the signal processing unit determines the distance between the transmitter and the receiver. A classifier (Kl) searches for images of humans in images of the image sequence. The signal processing unit decides whether an image of a human shows a person associated with a transmitter of the transmitter group and may generate a trajectory describing the movement of the camera.

An apparatus comprising a memory and a processor. The memory may comprise first parameters for an image sensor and second parameters for a LED. The processor may be configured to receive a first temperature from the image sensor, receive a second temperature from the LED, present a first adjustment to the image sensor and present a second adjustment to the LED. The first adjustment may be configured to scale the first parameters based on a difference between the first temperature and the predetermined temperature. The second adjustment may be configured to scale the second parameters based on a difference between the second temperature and the predetermined temperature. The processor may scale the first parameters and the second parameters in order to compensate for performance degradation of the image sensor caused by changes in the first temperature and the LED caused by changes in the second temperature.

An apparatus includes a first light source, a second light source, an image sensor circuit, and a processing circuit. The first light source is generally capable of emitting infrared light. The second light source is generally capable of emitting visible light. The image sensor circuit is generally responsive to both the infrared light and the visible light. The processing circuit is generally coupled to the image sensor circuit and configured to generate an image comprising both infrared information and color information.

An optical subsystem of a near-eye display system provides for projecting light of a virtual image of image content to an eye location, and provides for collecting light of the virtual image onto an exit pupil on a surface proximate to an outer surface of an eye when at the eye location. A subpupil modulator within an aperture in cooperation with the optical subsystem provides for forming a plurality of subpupils on a curved surface within the exit pupil, and provides for less than all of the light of the virtual image associated with one or more less than all of the plurality of subpupils to be projected to the eye location.
