Invisible Camera

1. Conceptual "Invisible Cameras":
• These are cameras designed to be extremely small, hidden, or camouflaged so they are effectively "invisible" to the casual observer. They're often used in surveillance, wildlife research, or security systems.
• Technologies used include pinhole cameras, button cameras, or lens-less cameras that can fit inside everyday objects.
2. Technological Innovation:
• Some research labs are working on lens-free imaging or computational photography, where sensors capture light differently, allowing the "camera" to be almost flat or hidden in materials like glass or fabric.
• Recent developments have even proposed transparent cameras built into displays or windows.
3. Marketing Term (Smartphones):
• Smartphone companies (like under-display cameras in Samsung, Xiaomi, or ZTE phones) use "invisible camera" to describe front-facing cameras hidden under the phone's screen.
• These cameras are invisible when not in use and don't interrupt the display, solving the notch or hole-punch design problem.
4. Artistic/Philosophical "Invisible Camera":

• • Some artists and filmmakers use "invisible camera" to describe shooting styles where the camera work is so natural and unobtrusive that the audience forgets they're watching something filmed.
