Methods, apparatuses, systems and software for focusing a camera on an object in any of a plurality of zones using graphics overlaid on a display

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 video or motion picture camera focusing system, 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 and process distance information for one or more subjects or objects in each of a plurality of detection zones in a field of view of a video or motion picture camera from the reflections; b. a video receiver configured to receive video from the video or motion picture camera; c. a graphics overlay unit configured to receive video information from the video receiver and the distance information from the distance measuring device, the graphics overlay unit comprising a video overlay and data 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 d. a monitor configured to display the video from the video or motion picture camera and the graphics overlaid on the displayed video.
