IMAGING DEVICE AND IMAGE SYNTHESIS PROGRAM

An imaging device includes an imaging element, a RAM, an adding synthesizing unit, and a high dynamic range synthesizing means. The imaging element captures an image of a subject and generates image data. The RAM temporarily stores plural pieces of image data that have been consecutively captured by the imaging element. The adding synthesizing means adds and synthesizes the plural pieces of image data stored in the RAM to generate synthesized image data. The high dynamic range synthesizing means synthesizes one of the plural pieces of image data with the synthesized image data to generate high dynamic range image data and outputs the generated high dynamic range image data.
