An abbreviation of "electronic vibration reduction. " The image sensing area is reduced and images stored in a memory buffer, where a series of images is compared to calculate the amount of movement produced by the vibration and the image sensing area automatically repositioned appropriately when an image is recorded. The disadvantages of this system are that the entire image sensor can not be used to record the image and that, while the system is relatively effective for recording movies, it is not particularly effective for recording still photographs. It can be applied to still photographs by retouching the image after recording to create the illusion of blur reduction; this type of blur reduction is referred to together with electronic VR as "digital blur reduction. " This method tends to increase noise and reduce image quality.
