Two channels: a correct channel for the appropriate eye and a left channel to the remaining eye. Both channels could be seen concurrently through the use of light-weight-polarizing filters ninety levels off-axis from one another on two video projectors.
In interlaced video, the horizontal scan lines of each and every finish frame are handled as if numbered consecutively and captured as two fields: an odd industry (upper field) consisting of your odd-numbered traces and a good field (lessen discipline) consisting in the even-numbered strains. Analog Exhibit gadgets reproduce each body, successfully doubling the body charge in terms of perceptible Total flicker is concerned.
Example of U-V colour aircraft, Y price=0.five The color design works by using the video coloration illustration and maps encoded coloration values to obvious hues reproduced by the method.
