A camera phone is a mobile phone which is able to capture either still photographs or motion video. Today more than half of all mobile phones in use are camera phones.[citation needed] 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 1990s, 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, 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.
