A camera phone is a mobile phone which is able to capture either still photographs or motion video.

History

The camera phone, like many complex systems, is the result of converging and enabling technologies. There are dozens of relevant patents dating back as far as the 1960s. Compared to digital cameras of the 90s, a consumer-viable camera in a mobile phone would require far less power and a higher level of camera electronics integration to permit the miniaturization. The CMOS active pixel image sensor "camera-on-a-chip" developed by Dr. Eric Fossum and his team in the early 1990s achieved the first step of realizing the modern camera phone as described in a March 1995 Business Week article. While the first camera phones, as successfully marketed by J-Phone in Japan, used CCD sensors and not CMOS sensors, more than 90% of camera phones sold today use CMOS image sensor technology.

The first wireless picturephone prototype known as intellect, developed in 1993 by inventor Daniel A. Henderson, was received by the Smithsonian National Museum of American History in 2007. This pioneering system and device was designed to receive pictures and video data sent from a message originator to a message center for transmission and display on a wireless device such as a cellular telephone . However, the integration of the cellular phone, the digital camera and a wireless internet infrastructure would take a few more years.

Over the years there have been many video phones and cameras that include communications technologies. None of them had focused on the integration with the wireless Internet which would allow instant media sharing with anyone anywhere. Such experiments include, for example, a device that was known as the Apple Videophone/PDA in 1995.. There were several digital cameras with cellular phone transmission capability shown by companies such as Kodak, Olympus in the early 90s There was also a digital camera with cellular phone designed by Shosaku Kawashima of Canon in Japan in May 1997.

On June 11, 1997, Philippe Kahn instantly shared the first pictures from the maternity ward where his daughter Sophie was born, with more than 2000 family, friends and associates around the world. A sharing infrastructure and an integrated cell-phone and camera combo augured the birth of instant visual communications.

In Japan, two competing projects were run by Sharp and Kyocera in 1997. Both had cell phones with integrated cameras. However, the Kyocera system was designed as a peer-to-peer video-phone as opposed to the Sharp project which was initially focused on sharing instant pictures. That was made possible when the Sharp devices was coupled to the Sha-mail infrastructure designed in collaboration with American technologist, Kahn. The Kyocera team was led by Mr. Kazumi Saburi.
