A focusing system for a cine-camera, comprising: a. a distance measuring device attachable to the cine-camera, wherein the optical axis of the distance measuring device is parallel to the optical axis of the camera, 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, and iii. logic configured to determine distance information for one or more subjects or objects in each detection zone of a two-dimensional array of detection zones in a field of view of the cine-camera from the reflections; b. a graphics overlay unit configured to receive video or motion picture information from the cine-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 a field of detection and position for each of the detection zones and 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 cine-camera that will bring the subject(s) and/or object(s) into focus, c. a monitor configured to display video or a motion picture from the cine-camera and the graphics overlaid on the displayed video or motion picture, characterized in that the field of detection and the position for each of the detection zones is defined by a unique set of elevation angular coordinates and azimuth angular coordinates relative to a fixed location in the cine-camera or the distance measuring device from which measurements to the subject(s) or object(s) in the field of view of the cine-camera can be determined such that the field of detection and the position and size of each detection zone remains fixed for a given angle or field of view of the cine-camera over a range of focus distances of the cine-camera, each unique set of elevation angular coordinates and azimuth angular coordinates includes a range of elevation angles and a range of azimuth angles, and no two detection zones overlap except at most at an endpoint of the ranges of elevation angles and azimuth angles. a. a distance measuring device attachable to the cine-camera, wherein the optical axis of the distance measuring device is parallel to the optical axis of the camera, 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, and iii. logic configured to determine distance information for one or more subjects or objects in each detection zone of a two-dimensional array of detection zones in a field of view of the cine-camera from the reflections; 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, and iii. logic configured to determine distance information for one or more subjects or objects in each detection zone of a two-dimensional array of detection zones in a field of view of the cine-camera from the reflections; b. a graphics overlay unit configured to receive video or motion picture information from the cine-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 a field of detection and position for each of the detection zones and 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 cine-camera that will bring the subject(s) and/or object(s) into focus, c. a monitor configured to display video or a motion picture from the cine-camera and the graphics overlaid on the displayed video or motion picture, characterized in that the field of detection and the position for each of the detection zones is defined by a unique set of elevation angular coordinates and azimuth angular coordinates relative to a fixed location in the cine-camera or the distance measuring device from which measurements to the subject(s) or object(s) in the field of view of the cine-camera can be determined such that the field of detection and the position and size of each detection zone remains fixed for a given angle or field of view of the cine-camera over a range of focus distances of the cine-camera, each unique set of elevation angular coordinates and azimuth angular coordinates includes a range of elevation angles and a range of azimuth angles, and no two detection zones overlap except at most at an endpoint of the ranges of elevation angles and azimuth angles.
