The present invention belongs to the technical field of light tracking devices, and is specifically an automatic focus following, dimming and light tracking device comprising a Z-axis rotating focus following mechanism, an X-axis rotating focus following mechanism, and a Y-axis translational focusing mechanism. The Z-axis rotating focus following mechanism comprises a pedestal and a surface shell rotating about a Z-axis. A tracking and positioning module is provided in front of the surface shell. A lamp holder body rotating about an X-axis is provided on the top surface of the surface shell. A lens, a distance measuring unit and an illuminance measuring unit are provided on the front end of the lamp holder body. The lamp holder body is provided internally with a lamp holder assembly to reciprocate linearly along a Y-axis. The lamp holder assembly is provided relative to the lens. During use, manual intervention is not required.

A method includes dividing a field of view into a plurality of zones and sampling the field of view to generate a photon count for each zone of the plurality of zones, identifying a focal sector of the field of view and analyzing each zone to select a final focal object from a first prospective focal object and a second prospective focal object.

Various embodiments disclosed herein include techniques for operating a multiple camera system. In some embodiments, a primary camera may be selected from a plurality of cameras using object distance estimates, distance error information, and minimum object distances for some or all of the plurality of cameras. In other embodiments, a camera may be configured to use defocus information to obtain an object distance estimate to a target object closer than a minimum object distance of the camera. This object distance estimate may be used to assist in focusing another camera of the multi-camera system.

This invention provides a vision system camera, and associated methods of operation, having a multi-core processor, high-speed, high-resolution imager, FOVE, auto-focus lens and imager-connected pre-processor to pre-process image data provides the acquisition and processing speed, as well as the image resolution that are highly desirable in a wide range of applications. This arrangement effectively scans objects that require a wide field of view, vary in size and move relatively quickly with respect to the system field of view. This vision system provides a physical package with a wide variety of physical interconnections to support various options and control functions. The package effectively dissipates internally generated heat by arranging components to optimize heat transfer to the ambient environment and includes dissipating structure (e.g. fins) to facilitate such transfer. The system also enables a wide range of multi-core processes to optimize and load-balance both image processing and system operation (i.e. auto-regulation tasks).

Exterior lighting on vehicles and buildings is typically used to illuminate scenes for better vision. The same exterior lighting can be used as part of an active sensor at discrete times during the sensor's active imaging cycles. In embodiments, an intelligent control module enables emitter output in accordance with the imaging system during active imaging cycles and enables emitter output in accordance with the non-imaging lighting control unit during non-imaging cycles. Embodiments of intelligent control modules can be used in security applications, in Automatic Driving Alert Systems and Autonomous Control Systems for commercial and passenger vehicles, and in low-altitude aircraft applications.

According to one embodiment, a ranging device includes storage and a processor. The storage is configured to store a statistical model generated by learning a bokeh that occurs in a first image affected by aberration of an optical system of a capture unit. The processor is configured to acquire a second image captured by the capture unit, acquire focus position information when the second image was captured, acquire a bokeh value indicating a bokeh of a subject in the second image, which is output from the statistical model by inputting the acquired second image to the statistical model, and convert the acquired bokeh value into a distance to the subject based on the acquired focus position information.

A system for external fish parasite monitoring in aquaculture, the system comprising: —a camera (52) suitable to be submerged in a sea pen suitable for containing fish, the camera being arranged for capturing images of the fish; and —an electronic image processing system (86) configured for identifying external fish parasites on the fish by analyzing the captured images, characterized by a camera and lighting rig (10) having a vertical support member (14), an upper boom (16) articulated to a top end of the support member (14) and carrying an upper lighting array (22), a lower boom (18) articulated to a lower end of the support member (14) and carrying a lower lighting array (24), and a housing (20) attached to the support member and carrying the camera (52), wherein the upper and lower lighting arrays (22, 44) are configured to illuminate, from above and from below, a target region inside a field of view of the camera (52).

To provide a system, a method and the like for acquiring more images or more quickly focused images. A control device acquires information regarding a situation of a range captured by an imaging device, determines a mode according to an assumed situation of the range captured by the imaging device among a plurality of focusing modes, and transmits designation information specifying the determined mode to the imaging device. The imaging device receives the designation information from the control device, and captures an image using the mode specified by the received designation information.

An electronic device includes a camera, a sensor for detecting a distance value relative to an object, a memory for storing calibration data for correcting a lens location of the camera based on the distance value detected by the sensor, and a processor. The memory stores instructions that, when executed, cause the processor to determine the lens location of the camera based on the distance value when the camera is operated, obtain lens location data for the distance value and the determined lens location, update the calibration data based on the lens location data, and determine the lens location of the camera based on the updated calibration data.
