Meandering on the electronic images in the film Technique


Monitor (TV screen) and color with the same 5-ray machine scanning technology like use of the film is \It is a continuous film by scanning the images depicting each of the film is converted to electronic images, which can be shown on television. This technique is called \The inherent advantages of the film so far, even if the film the film in the United States is still the main television program source. TV movie machine is the only television can be seen as means to achieve the film's print / distribution / screening (TV movie machine can scan film negatives and eliminates the need for printing directly from the film As part) television technology is invasive and therefore the film industry: they can be seen as a means of using film instead of a TV camera film technology which is in turn invaded the television. Figure 3 shows the flying-spot scanning telecine machine works. The light source device is a light film scanning cathode ray tube flying spot beam swept over the screen produce a series of bright points of light form a rectangular grating the grating in the film, focusing on the screen. In the film, photomultiplier tubes to the back of each point from the screen over the light transmission changes in the strength of these electrical signals into a corresponding signal amplification and correction by a television signal after the conversion of color video screen is usually the light through the color screen broken down into red,[link widoczny dla zalogowanych], green and blue beams. Were acting on the three photomultiplier tubes to obtain the corresponding three-color television signal. 1 video transfer film video film movie camera was the only intake equipment. But \TV cameras uptake of video in Figure 3 point scanning for television movie machine principle diagram DIGITAL & MICROGRAPHICIMAGING images and computer-generated graphics images can be film recorder (the equivalent of microfilm technology in the computer output of the camera or at COM recorder) records the motion picture film . Thus enriching the intake of the film image production means. 1 Computer Animation Camps digital special effects computer animation technology not only greatly increased the efficiency of the production of art films art films and enriched expression. \Three-dimensional animation technology. Richer means of digital film special effects. \Digital imaging technology to produce the electronic image by recording the film to the film, with traditional film imaging group reached a spurious connection with the point completely. A film recorder for high-definition cathode ray tube (CRT) as the exposure light source is high-resolution film recorder, but the most widely used techniques for exposure to laser light performance of more advanced technology products. This is because: (1) laser can be precisely controlled within a small range (such as 6 microns) produces high-energy CRT technology to avoid the glare of the limitations inherent in (2) laser spectroscopy (laser color) can choose to implement and spectral sensitivity of the film records the best match. The United States, Kodak Cineon film recorder as an example which uses 458 nm (blue), 543 nm (green) and 633 nm (red) and a helium neon laser as the light source and by Mann realized the middle film EXR5244 Color a good match. The recorder from the laser light source, acousto-optic modulator,[link widoczny dla zalogowanych], noise control, beam shaper,[link widoczny dla zalogowanych], beam combiner, polyhedron rotating mirror,[link widoczny dla zalogowanych], imaging lens, film transport device, digital data channel and the external interface components (Figure 4). In which the role of AOM is based on the requirements of the screen to control the color of three-color laser their intensity. The noise reduction device of the role is to ensure the stability of the laser energy. Three-color laser beam by the plastic synthesizer synthesis after the mixing of light in the beam bunch of 16-sided rotating mirror scans the beam formed by reflection and through a special lens on the film exposure imaging. Calculated by 6-micron spot. Images can be formed by exposure to 16,667 pixels / mm is significantly higher than normal film printing machine can achieve 5O line pairs / mm (roughly equivalent to 100 pixels / mm). Therefore,[link widoczny dla zalogowanych], this technology produced images with the lens is fully capable of shooting with traditional film camera lens comparable to the screen.
