At the center of all video field production systems is the portable video camera. A marvel of modern electronics, the video camera produces the electronic video signal.
Whether configured as a stand-alone camera with no built-in recording capability or as the camera section of a camcorder, all video cameras have a number of standard components, including an image sensor, viewfinder, camera control unit, and lens assembly (see Figure 3.1). This chapter will focus on portable video cameras and on the way the electronic image is generated and displayed. Lenses will be discussed in Chapter 6.
