Abstract

PURPOSE:To reproduce the result of photography of a film without being affected by the dynamic range of an image pickup element by applying exposure for plural number of times while controlling the exposure in a way that the photodetection quantity of the image pickup element differs, storing the result into a picture memory respectively for each exposure and synthesizing the picture in response to the exposure quantity. CONSTITUTION:An exposure control means applying plural number of times of exposure to a solid-state image pickup element 6, an exposure control means controlling the exposure so that the exposure quantity of each exposure and a picture synthesis means synthesizing the output picture of the solid-state image pickup element 6 for each exposure in response to the exposure are provided to the player. While the quantity of exposure is controlled with different photodetection quantity of the solid-state image pickup element 6, the film 2 is exposed for plural number of times and the detected output of the solid- state image pickup element 6 is synthesized in response to the exposure. Thus, the result of photography of the film 2 is reproduced with fidelity without being affected by the dynamic range of the image pickup means.
