Abstract: The present disclosure relates to a method of image preview in an image pickup apparatus. One embodiment is directed to a method that includes acquiring from an image sensor an image of a scene observed by an image sensor of the apparatus, generating a preview image obtained by applying to the acquired image a resolution reduction process to adapt it to the resolution of a display screen of a viewfinder of the image pickup apparatus, displaying the preview image on the display screen, generating an image of an area of the scene by extracting an area from the acquired image, and displaying the area image superimposed on the preview image or alternately with the preview image, the area image displayed having a resolution higher than that of the preview image and inferior or equal to that of the acquired image.
