Methods, Apparatuses, Systems and Software for Focusing a Camera

摘要

Methods, apparatuses, systems and software for focusing a camera are disclosed. The camera focusing system includes a distance measuring device, a video receiver that receives video/images, a graphics overlay unit, and a monitor. The distance measuring device includes an emitter that emits a radiation beam, a detector that detects reflected radiation, and logic that determines and processes distance information for subject(s) or object(s) in detection zones from the reflections. The graphics overlay unit receives video/image information from the video receiver and the distance information from the distance measuring device, and includes a video overlay and data processing unit that generates graphics indicating a field of detection and position for each detection zone and a direction and/or magnitude of a change in focus setting(s) to bring subjects or objects within each detection zone into focus. The monitor displays the video/image and the graphics overlaid thereon.

主权项

1. A focusing system for a video or motion picture camera, comprising:
a. a distance measuring device, comprising:
i. an emitter configured to emit a beam of radiation,ii. a detector configured to detect one or more reflections of the beam of radiation, andiii. logic configured to determine distance information for one or more subjects or objects in each of a plurality of detection zones in a field of view of the video or motion picture camera from the reflections; b. a graphics overlay unit configured to receive video information from the video or motion picture camera and the distance information from the distance measuring device, the graphics overlay unit comprising a video overlay and processing unit configured to generate graphics indicating (1) a field of detection and position for each of the plurality of detection zones and (2) a direction and a magnitude of a change in focus setting(s) for the subject(s) or object(s) within each detection zone not within a depth of field of the video or motion picture camera; and c. a monitor configured to display video from the video or motion picture camera and the graphics overlaid on the displayed video.
