Invention: camera
the history of camera can be traced back much further than the introduction of photography. Photographic cameras evolved from the camera obscura and continued to change through many generations of photographic technology, including daguerreotypes, calotypes, dryplates, film and digital cameras.
there are many camera that were created since 5th-4th Centuries B.C, I guess..
today Digital cameras differ from their analog predecessors primarily in that they do not use film, but capture and save photographs on digital memory cards or internal storage instead. Their low operating costs have relegated chemical cameras to niche markets. Digital cameras now include wireless communication capabilities (for example Wifi or Bluetooth) to transfer, print or share photos, and are commonly found on mobile phones.
Early Development:
The concept of digitizing images on scanners, and the concept of digitizing video signals, predate the concept of making still pictures by digitizing signals from an array of discrete sensor elements. At Philips Labs. in New York,Edward Stupp, Pieter Cath and Szilagyi filed for a patent on "All Solid State Radiation Imagers" on 6 September 1968 and constructed a flat-screen target for receiving and storing an optical image on a matrix composed of an array of photodiodes connected to a capacitor to form an array of two terminal devices connected in rows and columns. Their US patent was granted on 10 November 1970.Texas Instruments engineer Willis Adcock designed a filmless camera that was not digital and applied for a patent in 1972, but it is not known whether it was ever built. The first recorded attempt at building a digital camera was in 1975 by Steven Sasson an engineer at Eastman Kodak. It used the then-new solid-state CCD image sensor chips developed by Fairland Semiconductor in 1973. The camera weighed 8 pounds (3.6 kg), recorded black and white images to a cassette tape, had a resolution of 0.01 megapixels (10,000 pixels), and took 23 seconds to capture its first image in December 1975. The prototype camera was a technical exercise, not intended for production.
