Cuando la c\u00e1mara se mueve, el movimiento es electr\u00f3nicamente detectado y se genera un voltaje que hace mover las lentes. Esto altera el \u00e1ngulo de la luz que atraviesa el prisma y env\u00eda la imagen al sensor en la direcci\u00f3n opuesta al movimiento que realiza la c\u00e1mara. Por tanto, estabiliza la imagen antes de ser procesada. Ya que la imagen completa del sensor es usada con la estabilizaci\u00f3n de imagen \u00f3ptica, no se obtiene p\u00e9rdida de calidad de la misma. Sistemas comerciales famosos de estabilizaci\u00f3n \u00f3ptica son Canon IS, Nikon VR y Panasonic Lumix (y Leica) Mega OIS.<\/p>\n<p>&#160;<\/p>\n<p>En este video vemos c\u00f3mo funciona el estabilizador de Canon en un objetivo de su serie L<\/p>\n<p>&#160;<\/p>\n<div style=\"padding-bottom: 0px; padding-left: 0px; width: 425px; padding-right: 0px; display: block; float: none; margin-left: auto; margin-right: auto; padding-top: 0px\" id=\"scid:53357c8b-5919-4e32-8c25-305d27c17a37:3b03be2a-4d95-4c6b-a2db-eede344e7617\" class=\"wlWriterSmartContent\"><embed src=\"http:\/\/www.youtube.com\/v\/C60ehMe3wQ8&amp;feature=related\" type=\"application\/x-shockwave-flash\" wmode=\"transparent\" width=\"425\" height=\"350\"><\/embed><\/div>\n<p>&#160;<\/p>\n<p><font size=\"3\"><strong>Estabilizador de Imagen mec\u00e1nico<\/strong><\/font>    <br \/>Por desplazamiento del sensor CCD&#160; [editar]Comparable al m\u00e9todo anterior pero en vez de mover la lente se mueve el sensor de imagen.

En este tipo de sistemas, la superficie de la imagen \u00fatil es ligeramente menor que la superficie de la imagen. Cuando la c\u00e1mara se mueve, el encuadre menor se desplaza entre el \u00e1rea mayor del sensor CCD tratando de compensar el movimiento. El sistema electr\u00f3nico se encarga de determinar el \u00edndice de la fila y la columna de la imagen capturada por el sensor que debe presentarse como primera fila y primera columna de la imagen \u00fatil. Si por ejemplo, la c\u00e1mara se mueve ligeramente a un lado, el encuadre digital se mover\u00e1 en la direcci\u00f3n opuesta, cancelando el efecto del movimiento en el sensor de la c\u00e1mara. Aunque la t\u00e9cnica funciona efectivamente cancelando movimientos limitados de c\u00e1mara, al reducir el \u00e1rea aprovechable del sensor, se sacrifican la resoluci\u00f3n y claridad de la imagen.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Hay distintos tipos de estabilizadores y cada marca ha tomado caminos distintos.
