A short film generation apparatus (500; 510) for generating a short film using a plurality of still images, the apparatus comprising: an image display apparatus comprising a display unit operable to display an image; a still image obtainment unit operable to obtain a plurality of still images inputted from outside; and a scenario generation unit (505; 508) operable to generate a scenario that is replay information of a short film; wherein the image display apparatus includes: an original image holding unit operable to hold the plurality of still images each of which is an original image composed of a number of pixels larger than a number of pixels that is displayable on the display unit; an object judgment unit operable to judge whether or not an object including at least a character is included in the original image held in the original image holding unit, and generate object information in the case where the object is included in said original image, the object information indicating a form of an object area that is an area including the object in the original image; and a display image generation unit operable to i) extract, from the original image, at least a part of the object area, and ii) generate a display image with a number of pixels corresponding to the number of pixels that is displayable on the display unit, the extraction and generation being performed based on the original image specified by a user and the object information corresponding to the original image, wherein the object judgment unit includes an object extraction unit operable to extract a position and a size of the object in the original image, and add the extracted position and size of the object to the object information, the display image generation unit determines a part to be extracted from the original image, as an extracted part, based on the position and size of the object which are added to the object information, wherein the scenario generation unit (505; 508) generates the scenario by determining: an order of replaying said inputted still images; and a visual effect to be applied to the object in one of the still images according to the object information, and wherein the image display apparatus displays the extracted parts using the visual effect in the order that is temporally continuous, the extracted parts being included in the still images, and the order and the visual effect being determined for generating the scenario, wherein the object is a character area, and the display image generation unit includes a character area extraction unit operable to judge whether or not a character area is included in each of said one or more inputted still images, and extract information related to the character area in the case where the character area is included in the inputted still image, characterized in that the scenario generation unit (505;508) generates a scenario based on which a Pan effect is applied to the character area in the still image according to the judgment made by the character area extraction unit. an image display apparatus comprising a display unit operable to display an image;
