Method and device for generating images comprising motion blur

摘要

The invention relates to a method for processing video images comprising the steps for acquiring a plurality of video images during a time interval comprising a reference time t; associating a weighting factor with each of the video images, at least two of the video images having different weighting factors; memorising the video images; weighting each of the video images memorised with the associated weighting factor; generating an image called the reference image associated with the reference time t by averaging weighted video images. According to the invention, each video image is memorised with a resolution proportional to the weighting factor associated with said video image in order to reduce the memory space necessary for the storage of images and reduce the access time to the memorised images.

1. A method for acquiring and processing video images during a reference time interval, comprising:
storing the video images; associating a respective weighting factor with each said stored video image to obtain weighted video images such that at least two of said weighted video images have different weighting factors; adapting a resolution of each said weighted video image proportionally to said respective associated weighting factor; and, generating a reference video image associated with a reference time t comprised in said reference time interval by averaging the weighted video images,wherein each said respective weighting factor following a decreasing function of a time duration separating each of said video images from the reference time t.
