Camera phone

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.^{[citation needed]} 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^{[citation needed]}in the early 1990s achieved the first step of realizing the modern camera phone as described in a March 1995 Business Week article.^{[citation needed]} 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.^{[citation needed]}

The first wireless picturephone prototype known as intellect, developed in 1993 by inventor Daniel A. Henderson^[1], was received by the Smithsonian National Museum of American History in 2007^[2]. 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 ^[3]. However, the integration of the cellular phone, the digital camera and a wireless internet infrastructure would take a few more years.
