Abstract (en)
[origin: WO2012093209A1] The invention relates to a method for assisting in the shooting of a new digital photo (Pi+1) from an initial digital photo (?i) captured using a wide-angle lens (OBJ) combined with the digital sensor (CAPT) of a digital device (DISP), said method including: converting (13), in the digital device, the initial digital photo (?i) into a first intermediate image (Imi) using a mathematical projection function; converting (15), in the digital device, the first intermediate image (Imi) into a second intermediate image (Imi') by applying the inverse mathematical function of the mathematical projection function onto at least a portion of the first intermediate image (Imi); and simultaneously displaying (17), on a screen of the digital device, the second intermediate image (Imi') and an image (Im) viewed by the digital sensor so as to facilitate the shooting of the new digital photo (Pi+1).
