Disclosed is Light Detection and Ranging (“LiDAR”)-based camera metering, exposure adjustment, and image postprocessing. The LiDAR-based exposure adjustment may include emitting a laser from an imaging device, obtaining one or more measurements based on the laser reflecting off one or more objects in a scene and returning to the imaging device, adjusting exposure settings of the imaging device based on the one or more measurements, and capturing an image of the scene using the exposure settings. The LiDAR-based image postprocessing may include receiving an image of a scene and measurements or outputs from a LiDAR scan of the scene, and performing different adjustments to color values, contrast, brightness, saturation, levels, and other visual characteristics of different sets of pixels in the image based on different distance, material property, and/or other measurements obtained by the LiDAR for objects represented by the different sets of pixels.

A system and method of determining a tilt angle of a portable computing device using a sensor indicating gravitational pull on the device; determining the tilt angle of a camera of the device; identifying a tilt angle range from a plurality of predetermined tilt angle ranges; determining a first focal length setting using a first array that associates the tilt angle range with the first focal length setting; determining an adjustment increment using a second array that associates the adjustment increment with the tilt angle range; and determining a second focal length setting of the camera using the adjustment increment according to an autofocus scan range algorithm. A portable computing device including a processor; a camera; and a memory device including instructions operable to be executed by the processor to perform a set of actions, enabling the portable computing device to perform the method.

An electronic device includes a light detection and ranging (LiDAR) system including an Rx sensor including autofocus pixels distributed among image pixels for sensing image information. The LiDAR system also includes a Tx light source configured to output a pulse laser. A processor calculates a distance between the LiDAR system and a subject using the autofocus pixels included in the Rx sensor and drives the Tx light source based on the distance. The processor adaptively determines the transmission power of the Tx light source based on the distance to the subject, and controls the Tx light source to output a pulse laser according to the transmission power.

A control device includes a processor and a storage medium storing a program that, when executed by the processor, causes the processor to obtain a reference distance of a photographing device that includes a height of the photographing device or a distance from the photographing device to a target object, determine a range of a focus distance of the photographing device according to the reference distance, and control the photographing device to shoot a plurality of images while changing the focus distance within the range.

The device and method are intended for the standardization of picture taking without contact with the subject. Two light beamers converging at a distance within the range of camera focus are enabling reproducible viewing conditions via superimposition of the spots of the beamers on the subject and the light of the beamers are extinguished during picture taking in order not to bias the image. The device is constituted of a body (1) adaptable to a camera (1) with objective (2) and is including two light beamers (4A) and (4B) whose beams (5A) and (5B) are converging at a distance (D) within the focus range of the camera as well as a mechanism to extinguish the light beamers during picture taking. It can be improved by enabling the covering of the focus ring (2) and zoom ring (8) of camera (1).

Systems, methods, and non-transitory computer-readable media are provided for implementing a tracking camera system onboard an autonomous vehicle. Coordinate data of an object can be received. The tracking camera system actuates, based on the coordinate data, to a position such that the object is in view of the tracking camera system. Vehicle operation data of the autonomous vehicle can be received. The position of the tracking camera system can be adjusted, based on the vehicle operation data, such that the object remains in view of the tracking camera system while the autonomous vehicle is in motion. A focus of the tracking camera system can be adjusted to bring the object in focus. The tracking camera system captures image data corresponding to the object.

An illumination apparatus has a circular base plate and a plurality of tracks arranged radially about the base plate. LED modules are disposed upon the tracks, and transmission members coupled to the LED modules move the LED modules along the tracks. A distance measurement sensor is mounted on one side of the base plate, and is used to measure a distance value of an illuminated object. A processor is configured to determine a desired radius value for the plurality of LED modules based on the distance value and move the transmission members according to the desired radius value.

A technique for strobe shooting using automatic irradiation direction control. A strobe device includes a light emission section that emits light, and a drive unit that changes an irradiation direction of light emitted from the light emission section. Exposure conditions set to the camera are notified to the strobe device, and light emission conditions are set according to the exposure conditions. The irradiation direction of light emitted from the light emission section is determined based on the exposure conditions and the light emission conditions.
