A drone includes a frame and a plurality of motors attached to the frame. Each motor of the plurality of motors is connected to a respective propeller located below the frame. A tail motor is attached to the frame. The tail motor is connected to a tail propeller located above the frame. Cameras are attached to the frame and located above the frame. The cameras have fields of view extending over the plurality of propellers.

In some arrangements, product packaging is digitally watermarked over most of its extent to facilitate high-throughput item identification at retail checkouts. Imagery captured by conventional or plenoptic cameras can be processed (e.g., by GPUs) to derive several different perspective-transformed viewsfurther minimizing the need to manually reposition items for identification. Crinkles and other deformations in product packaging can be optically sensed, allowing such surfaces to be virtually flattened to aid identification. Piles of items can be 3D-modelled and virtually segmented into geometric primitives to aid identification, and to discover locations of obscured items. Other data (e.g., including data from sensors in aisles, shelves and carts, and gaze tracking for clues about visual saliency) can be used in assessing identification hypotheses about an item. Logos may be identified and usedor ignoredin product identification. A great variety of other features and arrangements are also detailed.

An advanced driver assistance apparatus, a vehicle having the same, and a method of controlling the vehicle are provided. The vehicle may acquire a first image of a road by a first image acquisition unit while traveling, acquire a second image of the road by a second image acquisition unit while traveling, recognize a first lane in the first image by a first lane recognizer, recognize a second lane in the second image by a second lane recognizer, determine whether at least one of the first lane recognizer or the first image acquisition unit has a failure by comparing the first lane with the second lane, and output failure information when at least one of the first lane recognizer or the first image acquisition unit is determined to have the failure.

An object is to provide a highly reliable display unit having a function of sensing light. The display unit includes a light-receiving device and a light-emitting device. The light-receiving device includes an active layer between a pair of electrodes. The light-emitting device includes a hole-injection layer, a light-emitting layer, and an electron-transport layer between a pair of electrodes. The light-receiving device and the light-emitting device share one of the electrodes, and may further share another common layer between the pair of electrodes. The hole-injection layer is in contact with an anode and contains a first compound and a second compound. The electron-transport property of the electron-transport layer is low; hence, the light-emitting layer is less likely to have excess electrons. Here, the first compound is the material having a property of accepting electrons from the second compound.

A fingerprint sensing system. The fingerprint sensing system includes: at least one sensor; at least one display device; at least one application processor; and at least one secure enclave processor. The application processor(s) receives fingerprint data from the sensor(s) and provides the fingerprint data to the secure enclave processor(s). The secure enclave processor(s) decodes the fingerprint data and provides a signal indicative of at least one matched node. The application processor(s), responsive to receipt of the signal indicative of the matched node(s), presents at least a portion of a synthetic fingerprint image via at least one display device corresponding to the matched node(s).

Visibility of a license plate and color reproducibility of a vehicle body are improved in a monitoring camera. A vehicle body area detection unit detects a vehicle body area of a vehicle from an image signal. A license plate area detection unit detects a license plate area of the vehicle from the image signal. A vehicle body area image processing unit performs processing of the image signal corresponding to the detected vehicle body area. A license plate area image processing unit performs processing different from the processing of the image signal corresponding to the vehicle body area on the image signal corresponding to the detected license plate area. A synthesis unit synthesizes the processed image signal corresponding to the vehicle body area and the processed image signal corresponding to the license plate area.

A lottery ticket pack verification system and method for simultaneously scanning a plurality of picked lottery ticket packs and for determining if the scanned lottery ticket packs are the correct lottery ticket packs based on a lottery ticket pack pick list.

Described are various embodiments of a light field display, adjusted pixel rendering method and computer-readable medium therefor, and vision correction system and method using same. In one embodiment, a computer-implemented method is provided to automatically adjust user perception of an input image to be rendered on a digital display via a set of pixels thereof, wherein the digital display has an array of light field shaping elements.

An imaging device includes an illuminator, a stage, a plurality of microlenses, an imaging element, and a controller. The controller is configured to control at least one of an irradiation position of light beams from the illuminator, and the position of the plurality of microlenses to realize a first state and a second state. A first angle of the light beams incident to each of the plurality of microlenses in the first state and a second angle of the light beams incident to each of the plurality of microlenses in the second state are different from each other.

A photographing method and device, a storage medium and an electronic apparatus are disclosed. The method includes the following. A current photographing scene is determined based on a current preview image. Based on the current photographing scene, pre-stored historical adjustment information of a photographing parameter matching the current photographing scene is acquired. Current adjustment information is determined based on the historical adjustment information. Adjustment is performed on the current preview image on the basis of the current adjustment information, and an adjusted current preview image is output.
