<p>The invention relates to a method for detecting a fade in a sequence of images which comprises the following steps: calculating, for each of the images of a window N consecutive images in length, termed the detection window, and for the image preceding the detection window, a luminance level on the basis of the luminance values associated with each of the pixels of each of the images; calculating, for each of the N images of the detection window, a difference of luminance level between the luminance level of the current image and the luminance level of the image preceding the current image; and deducing therefrom the presence of a fade for the detection window if, for at least k images of the detection window, said difference of luminance level is greater that a predefined threshold, with 2≦̸k≦̸N.</p> |
