Embodiments are directed to folded single sensor 3-D capture systems. An enclosure that includes an event camera, one or more beam generators, or an optical focusing system may be provided such that the beam generators may scan a scene. Paths may be scanned across objects in the scene with the beams. Events may be determined based on detection, by the event camera, of beam reflections that correspond to objects in the scene such that each beam reflection may be directed to a separate location on a sensor for the event camera by the optical focusing system. Trajectories may be determined based on the paths and the events such that each trajectory may be a parametric representation of a one-dimensional curve segment in a three-dimensional space. Three-dimensional information that corresponds to the objects may be generated based on the plurality of trajectories.

An image processing method and an electronic device are provided. The image processing method includes: displaying a first interface, where the first interface includes a first control; detecting a first operation on the first control; obtaining a first image stream in response to the first operation, where the first image stream is an image stream of first color space; converting the first image stream into a second image stream of second color space according to a demosaicing algorithm; performing downsampling and resampling on the second image stream to obtain a third image stream, where the third image stream is an image stream of the first color space, and a size of the third image stream is less than that of the first image stream; and performing image processing on the third image stream to obtain a fourth image stream.

A system for identifying defects and measuring geometric dimensions in cosmetic ophthalmic lens immersed in a Saline solution, the system, comprising: a) at least one camera for obtaining images of the cosmetic ophthalmic lens, the camera having an optical axis; b) at least one electronically controlled illumination module designed with Visible and infrared LEDs, segmented accordingly and suitably integrated to be positioned along the vertical optical axis for directing light at different angles of the cosmetic ophthalmic lens; c) a customised glass cuvette designed with concave, concentric and spherical surfaces to avoid adding more optical power to the cosmetic ophthalmic lens under inspection and with the radius of the interior surface of the cuvette designed to be bigger than the lens to enable locating the cosmetic ophthalmic lens to the centre of the cuvette during inspection; d) a strobe controller integrated to the illumination module and Camera that is capable of capturing multiple images in quick succession under different lighting conditions, utilising Visible LED and Infrared LED segments; (e) image processing means for capturing, processing and analysing multiple images to determine if the cosmetic ophthalmic lens is acceptable or rejected.

Systems and methods here may be used for a setup of image capturing of a gemstone, such as a diamonds that are of high clarity grades. The present embodiments can provide methods to capture a diamond surface and internal clarity features from a diamond table and through and of other facets. Systems and methods may be used to convert gemstone dimension information into azimuth, slope, and distance information and adjust the motorized stage accordingly for surface imaging. Further, a calibration method can consider the offsets between design and actual system alignment. A calibration process can be used to compensate the offsets. Further, an additional conversion can be derived to compensate the offset caused by the geometry of the gemstone. The methods can automatically capture surface reflection images on facets of the gemstone and internal features taken through facets of the gemstone.

An imaging device includes: a controller configured to perform control of each of a moving image capturing mode, in which a captured moving image is recorded as a moving image file, and a live distribution mode, in which a captured moving image is live-distributed to an external device; and an operation interface configured to be used for a user to input a stop instruction. In a case where the controller receives the stop instruction from the operation interface in the live distribution mode, the controller performs control of executing stopping confirmation processing for confirming with the user whether to stop moving image capturing before stopping the moving image capturing. In a case where the controller receives the stop instruction from the operation interface in the moving image capturing mode, the controller performs control of stopping the moving image capturing without executing the stopping confirmation processing.
