High Speed Video Imaging” is a phrase used for the technique in which a high speed camera is used to record fast moving objects. The vary camera records the action in the form of different images which are being stored temporarily at a destination on your storage medium. After the recording is finished you can rewind the whole recording in a slow motion. The best example of such video imaging is “Action Replay” on television during a soccer or cricket match.AOS technologies company Defines some of the best Quality and the Technology that were derived for The Camera ,so have a Look to it.

Evolution:

While the technique was in its early days, film was used as a recording point or storage base but today CCD (Charge Coupled Device) or CMOS (Complementary metal–oxide–semiconductor) are used as recording point and quite amazingly they serve as active pixel sensor.

What is CCD and CSOM?

CCD is a device for the movement of electrical charge, usually from within the device to an area where the charge can be worked upon. The CCD occupied a major place in the technology of digital imaging. Here pixels are represented by p-doped MOS capacitors. These capacitors are biased above the threshold for inversion when image acquisition begins. This scientific trick enables the conversion of incoming photons into electron charges at the semiconductor-oxide interface. These converted charges are interpreted by CCDs. CCD image sensors are widely used in the High Speed Video Imaging where high quality data are required.  CMOS (Complementary metal–oxide–semiconductor) can be used when a compromised image quality is not an issue.

Capacity of High Speed Camera:

When we watch a movie it is usually recorded at 24 frames/second but today’s most efficient High Speed camera can record 2,00,000 frames/second. The consumer oriented high speed camera can record 1000 frames/ second quite easily. These camera record these images and save them into DRAM. The terminology can be used as an abbreviation of Dynamic random-access memory. DRAM is a type of random-access memory that stores each bit of data in a separate capacitor within an integrated circuit. The capacitor can be either charged or discharged; these two states are taken to represent the two values of a bit, conventionally called binary or 0 and 1.
