Interlacing was invented as a way to lessen flicker in early mechanical and CRT video shows devoid of escalating the number of entire frames per next. Interlacing retains detail while necessitating decreased bandwidth compared to progressive scanning.[ten][eleven]
Pixels on Laptop or computer displays are usually square, but pixels Employed in electronic video normally have non-sq. part ratios, for instance Those people Employed in the PAL and NTSC variants of your CCIR 601 electronic video common plus the corresponding anamorphic widescreen formats.
In interlaced video, the horizontal scan lines of each and every finish frame are treated just as if numbered consecutively and captured as two fields: an odd subject (upper field) consisting of your odd-numbered traces and an even industry (decreased discipline) consisting in the even-numbered strains. Analog Exhibit gadgets reproduce Each individual frame, effectively doubling the frame rate so far as perceptible General flicker is anxious.
Simple crimson/cyan plastic glasses present the indicates to look at the photographs discretely to form a stereoscopic see on the written content.
