The image detection system may be configured to generate electronic information representative of images generated by the lens by detecting sequential images sensed by the image sensor. The detecting may not be done during certain periods of time. The controllable light source may be behind the lens and configured to controllably project light through the lens and back onto a scene in front of the lens. While in at least one mode, the light source control system may be configured to activate the controllable light source only while the image detection system is not detecting an image from the image sensor. The light source control system may be configured to activate the controllable light source and to cause it to emit light at an intensity which is sufficient to be readily visible to a normal human looking at the lens while within the scene, but not sufficient to materially alter the electronic information generated by the image detection system."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Camera with precise visual indicator to subject when within camera view","description":"A camera may include a lens, an image sensor, an image detection system, a controllable light source, and a light source control system.
