A crime center system generating a graphical user interface, which may be map-based, that facilitates efficient following of a moving object across cameras covering a geographic area. The system processes information on a network of cameras to determine the locations the cameras and their orientations. An object-tracking interface is generated by the system that includes an active camera view window presenting video from a camera capturing video of the geographic area that includes the tracked object. The system determines a set of the cameras, based on known locations and orientations, capturing images about the geographic space captured by the active camera. The system generates a “halo” of camera icons in the object-tracking interface around the periphery of the active camera view window, which provides a 360-degree view of available cameras about the active camera's location allowing a user to select a next active camera to efficiently track an object.

There is provided an information processing apparatus, an information processing method, and a program that allow for reduction in power consumption in authentication using multiple cameras. The information processing device performs camera search processing of searching for a camera suitable for authentication of a target among non-activated cameras yet to be activated, on the basis of a position and an angle of the target estimated from an image captured by an active camera which is an activated camera among multiple cameras, and activating the camera found by the search. The present technology can be applied to facial recognition systems.

A system for occlusion reconstruction in surround views using temporal information is provided. The system includes an active camera device generating image data describing a first view of an operating environment and a computerized visual data controller. The controller includes programming to analyze the image data to generate a three-dimensional computerized representation of the operating environment, utilize the image data and the representation of the operating environment to synthesize a virtual camera view of the operating environment from a desired viewpoint, and identify an occlusion in the virtual camera view.

The invention relates to a method and device for characterising a terminal comprising a light source and at least one camera. This method makes it possible to characterise a terminal comprising a light source and at least one camera. The method comprises the following steps: - illuminating (E10), with the light source, an at least partially reflective surface; - obtaining (E20) an image of the surface acquired with a camera referred to as the "active camera" from among the at least one camera; - calculating (E60), from this image, the position of a point on the surface within a highlighted light spot; - estimating (E90) a relative position of the light source with respect to the position of the active camera (CAM) on the basis of: (i) the position of the point; and (ii) a position of the surface relative to a plane of the terminal.

The invention relates to a multi-thread-based video processing system and a frame extraction interval dynamic adjustment method thereof. The method comprises the following steps: acquiring the number N of active cameras accessed to the system; obtaining average ambient light intensity, and determining single-frame processing time T based on the ambient light intensity in combination with pre-configured single-frame processing basic time; and a first frame extraction interval t1 = N * T / (G * a) is calculated and determined, G is the total computing power of hardware, and a is a computing power coefficient. Compared with the prior art, the number of the active cameras and the average ambient light intensity are introduced, so that the frame extraction interval can be influenced in advance when the access number of the cameras is changed and the time elements are changed, and feedback adjustment can be performed without waiting for the factors to influence the lagging of the occupancy rate of the processor, so that the problem of reflection lagging can be solved on one hand; and the fluctuation of the overall GPU occupancy rate can also be reduced.

An electronic device, method, and computer program product provide improved zoom functionality for a hand-held electronic device. The electronic device includes a front camera and a back camera and a distance measuring unit to detect an amount of lateral movement of the electronic device relative to a user. The processor activates an automated (auto) zoom feature while an active camera is selected to receive and capture a first image.

Vehicle headlamps are typically used to illuminate scenes for better vision. The same headlamps can be used as part of an active camera at discrete times during the camera's imaging periods. In embodiments, a lighting control module utilizes an electronic control module to control on / off states of the headlamps during a set of non-imaging periods of the camera system and a camera control configured to control multiple on / off states of the set of headlamps during a set of imaging periods of the camera system. Embodiments of lighting control modules can be used in Advanced Driver Assistance Systems (ADAS) and Autonomous Control Systems for commercial and passenger vehicles.
