Devices or systems with display designs to include both a main display zone and a peripheral display zone that collectively form a seamless contiguous display area for displaying images, content or information over the two zones as a single display area and further allowing for operating the peripheral display zone independently from the main display zone to display certain images, information, or content only on the peripheral display zone even when the main display zone is turned off. In addition to providing display functions separate from or in combination with the display functions by the main display zone, the peripheral display zone based on the disclosed technology can be used to provide for certain sensing functions by including one or more sensors under the display area for the peripheral display zone.

A low-power face identification method includes detecting an object image, extracting two-dimensional image information of the object image, and when the two-dimensional image information is undetected as a face feature, disabling all related components for inhibiting a three-dimensional face recognition function.

This application relates to a laptop computer. The laptop computer includes a base portion pivotally coupled to a lid portion is described. The laptop computer includes a display assembly carried by the lid portion, where the display assembly includes a light-transmissive cover, a display layer overlaid by the light-transmissive cover, a display stack electrically coupled to and overlaid by the display layer, and a light pattern recognition module adjacent to the display stack and overlaid by the display layer. The light pattern recognition module includes (i) a light pattern projector that projects a light pattern directly through the display layer.

Systems and methods for through-display imaging. An optical imaging sensor is positioned at least partially behind a display and is configured to emit shortwave infrared light at least partially through the display to illuminate an object, such as a fingerprint, in contact with an outer surface of the display. Surface reflections from the object are received and an image of the object can be assembled.

A captured image acquisition section 50 acquires from an imaging apparatus 12 data of a polarized image captured of a target object and stores the image data into an image data storage section 52. A region division section 58 in a normal line information acquisition section 54 divides a plane of the image into regions according to a predetermined criterion such as a polarization degree or luminance. A normal line calculation section 60 obtains a distribution of normal lines of each region by applying either a specular reflection model or a diffuse reflection model thereto. An integration section 62 integrates the distributions of normal lines of the regions into a normal line distribution of the entire image. An output data generation section 56 performs information processing using the normal line distribution and outputs the result of the processing.

In an image projection system, a computing device generates conversion information for converting camera coordinates used by an imaging device and projector coordinates used by an image projection device based on a positional relationship between a projection pattern image and an imaging pattern image, the imaging device images a subject including a person, the computing device detects a first position indicating a position related to the camera coordinates in a specific region in the person, the computing device converts information on the first position into information on a second position indicating a position related to the projector coordinates in the specific region based on the conversion information, and the image projection device projects a warning image for overlapping with an entire region of the specific region based on the information on the second position.
