Each sensor only records the information on a light color. Then just saving and restoring the three RGB components of a color monitor that supports three RGB inputs: there are three signals instead of one. Not only should they triple all cable connections between devices, but also triple the recording tracks on a VCR, triple all online videos and games production equipment.
The easiest solution would have been accelerating the scan rate, but this also required to increase the frame rate, which was expensive. A more clever solution was to miss a row in each image, thus doubling the scan rate while keeping the same bandwidth. Thus, a first pass displays all the odd lines in half the time for a whole image and a second pass shows missing line pairs: this is called interlacing. We obtain the same number of scan lines to an image, and twice flushed the screen to display a single image.
Due to the capture of two frames each second of 1:50, the time of exposure in video (25i). The first cameras operating on the same principle as televisions analyzed the image formed by the lens with a CRT. Since the late 1980s, they have a photo sensor CCD or CMOS type. There are different formats of video images, which depend mainly on frequency of vertical sweep of images. It can be seen that there is a difference between the number of lines composing the frame and the number of lines displayed.
How now add to Y color information to regain our original RGB? Since there was already light (Y), it was necessary to color the black/ white with color information, they had no light value, but only indications of hue and saturation. Once the b/w was colorized, they had to find the trick that would transmit light (Y) and chroma (C).
Free lines are partially taken advantage of: they place the signals teletext, subtitling and also the time-code of professional video equipment. There are two scanning frequencies of the image: The vertical scanning, which takes place from top to bottom is used to compose the image. It is done 50 or 60 times per second.
This is the shooting mode selected for films shot in HD TV or D cinema to be transferred and projected on 35mm. 25 progressive (25p) then give the camera an exposure time of 1/25 of second, which is too long in terms of temporal resolution. Preference is given limited integration frames 1:50 s (electronic shutter) time.
Analog video standard across the world include NTSC, PAL and SECAM. PAL or SECAM standards have no relationship with the scan of an image, these standards only allow you to add color to black and white images. In the early days of television, only the luminance defines the image by a number of horizontal dots and also by three factors shade of gray.
Engineers used the additive synthesis of red, green and blue (contrary paper absorbs light and uses the compound of subtractive cyan, magenta and yellow) Red, green and blue are the primary colors of additive synthesis. Similarly, the cyan, magenta and yellow are the primary subtractive colors. Shooting in color is done through an optical prism, which splits light on three sensors, otherwise there is red, green and blue filters.
