Because of technological constraints or artistic requirements, the image may represent the scene over a period of time. Most often this exposure time is brief enough that the image captured by the camera appears to capture an instantaneous moment, but this is not always so, and a fast moving object or a longer exposure time may result in blurring artifacts which make this apparent. As objects in a scene move, an image of that scene must represent an <a href="/wiki/Integral" title="Integral">integration</a> of all positions of those objects, as well as the camera's viewpoint, over the period of <a href="/wiki/Exposure_(photography)" title="Exposure (photography)">exposure</a> determined by the <a href="/wiki/Shutter_speed" title="Shutter speed">shutter speed</a>. In such an image, any object moving with respect to the camera will look blurred or smeared along the direction of relative motion. This smearing may occur on an object that is moving or on a static background if the camera is moving. In a <a href="/wiki/Film" title="Film">film</a> or <a href="/wiki/Television" title="Television">television</a> image, this looks natural because the human eye behaves in much the same way. </p><p>Because the effect is caused by the relative motion between the camera, and the objects and scene, motion blur may be manipulated by <a href="/wiki/Panning_(camera)" title="Panning (camera)">panning</a> the camera to track those moving objects. In this case, even with long exposure times, the moving objects will appear sharper while the background will become more blurred, with the resulting image conveying a sense of movement and speed.<sup id="cite_ref-2" class="reference"><a href="#cite_note-2"><span class="cite-bracket">&#91;</span>2<span class="cite-bracket">&#93;</span></a></sup> </p> <div class="mw-heading mw-heading3"><h3 id="Animation">Animation<span class="anchor" id="Computer_animation"></span></h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Motion_blur&amp;action=edit&amp;section=3" title="Edit section: Animation"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <figure typeof="mw:File/Thumb"><a href="/wiki/File:Figure-Animation2.gif" class="mw-file-description"><img src="//upload.wikimedia.org/wikipedia/commons/thumb/1/11/Figure-Animation2.gif/400px-Figure-Animation2.gif" decoding="async" width="400" height="150" class="mw-file-element" srcset="//upload.wikimedia.org/wikipedia/commons/thumb/1/11/Figure-Animation2.gif/600px-Figure-Animation2.gif 1.5x, //upload.wikimedia.org/wikipedia/commons/thumb/1/11/Figure-Animation2.gif/800px-Figure-Animation2.gif 2x" data-file-width="1000" data-file-height="375" /></a><figcaption>Two animations rotating around a figure, with motion blur (left) and without</figcaption></figure> <p>In computer animation this effect must be simulated as a virtual camera actually does capture a discrete moment in time. This simulated motion blur is typically applied when either the camera or objects in the scene move rapidly. </p><p>Without this simulated effect each frame shows a perfect instant in time (analogous to a camera with an infinitely fast shutter), with zero motion blur. This is why a video game with a frame rate of 25-30 <a href="/wiki/Frames_per_second" class="mw-redirect" title="Frames per second">frames per second</a> will seem staggered, while natural motion filmed at the same frame rate appears rather more continuous. Many modern video games feature motion blur, especially <a href="/wiki/Vehicle_simulation_game" title="Vehicle simulation game">vehicle simulation games</a>. </p><p>Some of the better-known games that utilise this are the recent <a href="/wiki/Need_for_Speed" title="Need for Speed">Need for Speed</a> titles, <a href="/wiki/Unreal_Tournament_3" title="Unreal Tournament 3">Unreal Tournament III</a>, <a href="/wiki/The_Legend_of_Zelda:_Majora%27s_Mask" title="The Legend of Zelda: Majora&#39;s Mask">The Legend of Zelda: Majora's Mask</a>, among many others. There are two main methods used in video games to achieve motion blur: cheaper full-screen effects, which typically only take camera movement (and sometimes how fast the camera is moving in 3-D Space to create a radial blur) into mind, and more "selective" or "per-object" motion blur, which typically uses a <a href="/wiki/Shader" title="Shader">shader</a> to create a velocity buffer to mark motion intensity for a motion blurring effect to be applied to or uses a shader to perform geometry extrusion. Classic "motion blur" effects prior to modern per-pixel shading pipelines often simply drew successive frames on top of each other with slight transparency, which is strictly speaking a form of <a href="/wiki/Video_feedback" title="Video feedback">video feedback</a>. </p><p>In pre-rendered computer animation, such as <a href="/wiki/Computer_Generated_Imagery" class="mw-redirect" title="Computer Generated Imagery">CGI</a> movies, realistic motion blur can be drawn because the renderer has more time to draw each frame. <a href="/wiki/Temporal_anti-aliasing" title="Temporal anti-aliasing">Temporal anti-aliasing</a> produces frames as a composite of many instants. Frames are not points in time, they are periods of time. If an object makes a trip at a linear speed along a path from 0% to 100% in four time periods, and if those time periods are considered frames, then the object would exhibit motion blur streaks in each frame that are 25% of the path length. If the shutter speed is shortened to less than the duration of a frame, and it may be so shortened as to approach zero time in duration, then the computer animator must choose which portion of the quarter paths (in our 4 frame example) they wish to feature as "open shutter" times. They may choose to render the beginnings of each frame, in which case they will never see the arrival of the object at the end of the path, or they may choose to render the ends of each frame, in which case they will miss the starting point of the trip. Most computer animations systems make the classic "fence-post error" in the way they handle time, confusing the periods of time of an animation with the instantaneous moments that delimit them. Thus most computer animation systems will incorrectly place an object on a four frame trip along a path at 0%, 0.33%, 0.66%, and 1.0% and when called upon to render motion blur will have to cut one or more frames short, or look beyond the boundaries of the animation, compromises that real cameras don't do and synthetic cameras needn't do. </p><p><a href="/wiki/Motion_lines" title="Motion lines">Motion lines</a> in <a href="/wiki/Cel_animation" class="mw-redirect" title="Cel animation">cel animation</a> are drawn in the same direction as motion blur and perform much the same duty. <a href="/wiki/Go_motion" title="Go motion">Go motion</a> is a variant of <a href="/wiki/Stop_motion" title="Stop motion">stop motion</a> animation that moves the models during the exposure to create a less staggered effect. </p> <div class="mw-heading mw-heading3"><h3 id="Computer_graphics">Computer graphics</h3><span class="mw-editsection"><span class="mw-editsection-bracket">[</span><a href="/w/index.php?title=Motion_blur&amp;action=edit&amp;section=4" title="Edit section: Computer graphics"><span>edit</span></a><span class="mw-editsection-bracket">]</span></span></div> <p>In <a href="/wiki/2D_computer_graphics" title="2D computer graphics">2D computer graphics</a>, motion blur is an artistic filter that converts the <a href="/wiki/Digital_image" title="Digital image">digital image</a><sup id="cite_ref-3" class="reference"><a href="#cite_note-3"><span class="cite-bracket">&#91;</span>3<span class="cite-bracket">&#93;</span></a></sup>/<a href="/wiki/Bitmap" title="Bitmap">bitmap</a><sup id="cite_ref-4" class="reference"><a href="#cite_note-4"><span class="cite-bracket">&#91;</span>4<span class="cite-bracket">&#93;</span></a></sup>/<a href="/wiki/Raster_image" class="mw-redirect" title="Raster image">raster image</a> in order to <a href="/wiki/Computer_simulation" title="Computer simulation">simulate</a> the effect.
