The high performance video camera has a great application prospect in the fields such as medical imaging,ultrared weak light imaging and satellite imaging.
As the bridge and medium between audience and judiciary administrator, journalists through their cameras let audience catch the point of trial process about many important cases regarded by the public.
In order to obtain high definition, especially high quality lunminance signals,the methods of picking up signals in HDTV video cameras are developed, such as double-green(DG) and 4-CCD method appears one after another.

To decrease number of samples for the implementation of color space transformation, a method for modeling the chromatic characterization of video cameras was proposed.
The system consists of a commercial CCD camera, narrow-band composite filter lens, an image capturing card, an industrial computer, a welding control unit, a GMAW power source, and a worktable.
A HE-NE laser was used to illuminate the particles inside the CFB through two glass windows and the in-line diffraction pattern was recorded by a CCD camera.
The setup is equipped with a specially developed thermocuvette, a laser, a CCD video camera, a photodetector, units for processing electronic signals, and a computer.
In this case, an individual computer transmitting information to the control system of the storage ring via the local-area network is used in each beamline to process information from a beam position sensor equipped with a video camera.
The substorm on March 12, 1991 is studied using the data of ground-based network of magnetometers, all-sky cameras and TV recordings of aurora, and measurements of particle fluxes and magnetic field onboard a satellite in the equatorial plane.
The design of the collimator is based on the use of a 12-collimator radial neutron camera that was developed earlier and two complementary compact neutron cameras.
It is proposed that the compact neutron cameras be placed inside the shielding blocks located in the equatorial (nine collimators) and diverter diagnostic (seven collimators) ITER ports.
The linear decreases of the surface areas of hanging drops from a polypropylene fiber for the same liquids were also monitored using both plan and side view video cameras for comparison.
Under the condition of the littie improvement of the common camera and its normal function not to be affected,was the camera changed into Ext Sync Camera.And then,some Ext curcuit were added to SEG-1210p trick-signed generator, the inserting of word or / and figure by keyed trick was realized.
The chopping modulation circuit model of the pyroelectric infrared camera is introduced. The circuit design and analysis for the circuit model were made.
This paper points out the problems of CCD camera in energy distribution measurementfrom various aspects including the photo-elastic response non-uniformity and non-linearity in CCD sensor array; the scanning system conversion. the automatic gain control circuit and the γ correction circuitin camera. Solutions to each mentioned above are also discussed. In the meantime, the integral method to decrease noises is introduced.
