<p>The invention relates to a method for compensating motion blur in connection with vibrations in an image recording apparatus (1), such as a camera, for stabilization of recorded images, wherein use is made of a reference image. According to the invention, a frame (2) of a recorded image is selected for image stabilization and the degree of sharpness (3) in the selected frame is evaluated and compared (5) with a previously saved reference value (4) for the degree of sharpness for a previously selected frame. The last chosen frame is used to update (6) a video sequence and the degree of the sharpness for the last chosen frame is saved (7) as a new reference value if the degree of sharpness for the last chosen frame is deemed to be better (5) than or equally as good as the reference value for the degree of sharpness for a previously selected frame. The reference value (4) for the degree of sharpness for a previously selected frame is saved with reduction (8) of the value of sharpness and the previously selected frame is used in the video sequence if the degree of sharpness for the last chosen frame is deemed to be worse (5) than the reference value for the degree of sharpness for the previously selected frame. As a result of the invention, a method which, by relatively simple action, can effectively compensate for motion blur in connection with vibrations is provided.</p> |
