INTERLACING When referring to a computer monitor or another display, interlace or interlacing is a description of how the picture is created. Interlacing is supported by the following formats, where it is optional: Interlacing is a form of incremental decoding, because the image can be loaded incrementally. For example: Interlaced GIF is a GIF image that seems to arrive on your display like an image coming through a slowly opening Venetian blind. 2. Computer Graphics MCQ-8. Computer graphics is responsible to display a picture of any size on our computer screen. Interlacing is the technique used in standard CRT monitors when refreshing the screen. Screen Resolution. Various algorithms and techniques are used to generate graphics on computer screens. It involves computations, creation, and manipulation of data. In computer graphics, the frequency at which the screen is redrawn is called: Aspect ratio Interlacing-- Refresh rate Screen resolution. Verfication Code. After that discusses the concept of clipping, which means removal of objec. 4. 1. stream

A fuzzy outline of an image is gradually replaced by seven successive waves of bit streams that fill in the missing lines until the image arrives at its full resolution. Interlacing allows for a faster refresh rate by having less information . 2 0 obj
What is interlacing?

Because each interlaced video frame is two fields captured at different moments in time, interlaced video frames can exhibit motion artifacts known as interlacing effects, or combing, if recorded objects move fast enough to be in different positions when each individual field is captured.

[citation needed], Interlacing has been criticized because it may not be clear to viewers when the image has finished rendering, unlike non-interlaced rendering, where progress is apparent (remaining data appears as blank). The frame buffer is regularly sent to the display device (eg 60 times per second) whether the frame buffer has been . This is a fundamentally impossible process that must always produce some image degradation, since it ideally requires "temporal interpolation" which involves guessing the movement of every object in the image and applying motion .
