Common camera focus dots are not always effective in helping a digital camera user focus on the exact point of interest for a photograph. A system is needed that can improve the ability of digital cameras to automatically focus on the exact area that the user wishes to capture.
The novel solution is to use an infrared or ultraviolet emitter that is detectable by the camera . The approach is to connect an infrared/ultraviolet emitter to a camera (via wired or wireless connection) and provide the software tools/settings for that camera to be able to detect and autofocus on the point of intersection .
The camera detects the infrared/ultraviolet point of contact and uses it to adjust the camera to focus at the point of intersection with the subject. Currently most cameras use known points in its field of view as the autofocus point. The novel system allows the user to both see the infrared/ultraviolet beam and aim the beam at the area/point of interest for image capture. This enables the user to use the beam's point of contact as a reference point when for focusing, as well as other camera functions. The new emitter increases the accuracy of the autofocus functionality currently available.
To implement the infrared or ultraviolet emitter with a digital camera in a preferred embodiment , the infrared beam is first activated. The camera switches to a mode that allows the user to see the both subject and the emitted beam . The cam...
