ORIENTATION SYSTEM FOR IMAGE RECORDING DEVICES

摘要

An image recording device having a projected viewfinder is described that projects individual, or multiple sets of synchronized framing beams onto a target image that are coaxially aligned with the field of view of the camera. The set of framing beams is projected onto the target image beyond the scope of the field of view being recorded by the image recording device but still within the field of vision of the operator of the device. In this way, the operator of the image recording device will be able to clearly see the framing beams identifying the limits of the recorded areas, while not having any portion of the field of view of the image recording device obscured by the framing beams themselves.

主权项

1. An image recording device having a projected viewfinder for establishing an outer boundary of a field of view for a target image, comprising:
an objective lens having a field of view; and at least one set of light beam emitters, each of the light beam emitters spatially positioned around an outer perimeter of the objective lens at incrementally greater distances to project a correspondingly wider set of framing beams, each set of framing beams corresponding to the at least one set of light beam emitters being interchangeably activated and deactivated to project one corresponding set of framing beams at a time, wherein the at least one set of light beam emitters projects a corresponding set of framing beams which circumscribes at least in part said outer boundary of the field of view of the objective lens and which is projected onto the target image beyond the scope of the field of view of the objective lens, thereby avoiding interference with the field of view; wherein activation and deactivation of the at least one set of light beam emitters is coordinated with a change in a level of magnification of the field of view of the objective lens to maintain the coaxial alignment of the corresponding set of framing beams to the field of view of the objective lens.
