Raster Scan associates degreed, random scan square measure the mechanisms employed in displays for rendering the image or picture.
The most distinction between formation scan and random scan lies within the drawing of an image wherever the formation scan points the nonparticulate radiation at the whole screen however incorporating only one line at a time within the downward direction. On the opposite hand, within the random scan, the nonparticulate radiation is guided on simply those regions of the screen wherever the image really lies.
Let’s see the difference between random scan and raster scan:
|S.NO||Random Scan||Raster Scan|
|1.||The resolution of random scan is higher than raster scan.||While the resolution of raster scan is lesser or lower than random scan.|
|2.||It is costlier than raster scan.||While the cost of raster scan is lesser than random scan.|
|3.||In random scan, any alteration is easy in comparison of raster scan.||While in raster scan, any alteration is not so easy .|
|4.||In random scan, interweaving is not used.||While in raster scan, interweaving is used.|
|5.||In random scan, mathematical function is used for image or picture rendering.||While in which, for image or picture rendering, raster scan uses pixels.|
|6.||It is suitable for applications requiring polygon drawings.||It is suitable for creating realistic scenes.|
