Get ready for single-pixel cameras

A single-pixel camera? Yes, there is such a thing and it promises to be more useful than it at first might appear. The basic idea behind the new camera is to drastically reduce the amount of information needed to represent an image. This takes place by compressing information in the image as it is digitized, rather than compressing image data after digitization. It involves a single-photon detector whose output is digitized and then transmitted to a digital signal processor. The DSP uses sophisticated algorithms to reassemble the data into a version of the original image. Researchers at Rice University recently constructed a bench-top setup that demonstrates these principles. Their demo uses a single- photon detector, some lenses, and a digital micromirror chip. The

CMOS Cameras
Complementary metal oxide semiconductor (CMOS) cameras use image sensors that operate at lower voltages than charged coupled devices (CCDs), reducing power consumption for portable applications. Each CMOS active pixel sensor cell has its own buffer amplifier, and can be addressed and read individually. 
CCD Cameras
CCD (couple-charged device) cameras are a type of image capture device that utilize an image sensor to register visible light as a recordable electronic signal to visually archive captured stills and video. Of the three types of digital cameras (the others being CMOS and CID), CCD cameras are the most developed and commonly used.
Frame Grabbers
Frame grabbers are image processing computer boards that capture and store image data for industrial applications such as quality control.
Video Cameras
Video cameras record live-action scenes that are available for viewing via a stored or transmitted video feed. This allows the user to create a permanent and detailed chronicle of events. Video cameras record dozens of pictures (or frames) a second that when viewed in succession, clearly distinguish the translation of an object or person over time.
Low Light Cameras
Low light cameras are a type of video camera with extreme photon sensitivity, and are excellent for recording in situations where only ambient levels of light are available. Common deployments include overnight surveillance and remote machine monitoring.
