Claim Text:
1. A method for processing a video sequence formed by at least two video images, said method comprising: obtaining said at least two video images using a first capture module with a first field of view, each video image representing a same scene captured at different instants or from different points of view, wherein said method further comprises: determining the location of at least one video image into at least one overall image obtained by a second capture module with a second field of view greater than said first field of view, said overall image representing the scene captured at different instants or from different points of view; determining luminance information from said at least one overall image and the location of said at least one video image into said at least one overall image; down-converting a dynamic range of said video images taking into account said luminance information the determining of the location of said at least one video image into said at least one overall image being performed by determining a distortion metric that corresponds to the following sum of absolute difference: Where C represents a value of a determined metadata of said at least one video image, S represents a value of said determined metadata of said at least one overall image of height N and width M, (x,y) the coordinates of a starting point of said at least one video image and (dx, dy) the coordinates of a tested location of said at least one video image in said at least one overall image, said location corresponding to a point of said at least one overall image, whose coordinates correspond to a couple (dx, dy) minimizing the distortion Dist x,y .
