My first suggestion is that you tell us the make and model of camera. Couple of things could be wrong here: Camera has a digital BW effect. The RCA input is actally a component input (marked Yr-Cr-Br) and your lead is composite, so you are only getting one of the three colour channels. The particular input has been switched to s-video on your tv or you have a fault with the camera.
1. A CCD camera works exactly like a regular camera, but instead of focused light falling on film, the light strikes the CCD.
2. A CCD works sort of like an array of thousands or millions of tiny solar cells, each one a pixel, collecting a tiny bit of light and converting it into electrons. The electrons are collected by an analog to digital converter that changes the pixel's value into a digital value. From there the data is manipulated by a processor or stored to memory.
1. IR = infrared, refers to the frequency spectrum of light (color). There are two commonly used IR bands for imaging. Near-IR is just outside the region of colors we can see. People use near IR to take interesting pictures and can be used to view an unlit area, as perceived by humans, that is illuminated by a near-IR light (humans can't see the near-IR light source). This has been used in wildlife photography and surveillance. Thermal-IR is a spectral band where heat is emitted. Thermal-IR is far away from our visual capability. This requires a special imaging sensor and lens. Thermal IR cameras image the heat radiated off surfaces. These cameras generally start off at $10,000 for cheap systems.
2. CCD = charge coupled device, a type of image sensor used in cameras. CCD sensors can sense light in the near UV down to near IR. CCD sensors can't be used to image thermal-IR. Filters are usually placed in front of the sensor to block UV and IR so just the visible spectrum is sensed.
