1. A method for processing an image according to one reframing method to obtain a reframed image for which the format ratio is equal to a target format ratio, the method comprising the steps of: associating a saliency value with each pixel of said image; applying a face detection method and a text detection method of said image calculating a confidence parameter from said saliency values and from outputs of said face and text detection methods; comparing the confidence parameter to a first predetermined threshold value; selecting said reframing method in a set of at least two reframing methods according to the result of said comparison, and reframing said image using the selected reframing method; wherein, when said confidence parameter is less than said predefined threshold value, checking whether at least one zone of text is detected in said image and said reframing method is selected according the result of said checking; wherein, when no text zone is detected, the processing method comprises further checking whether at least one face is detected and said reframing method is selected according to the result of said further checking.
