Abstract:
An image sensing method comprising:an image sensing step of obtaining image data of a plurality of images of an object in a plurality of different luminous exposures; a first storing step of storing image data of said plurality of images of an object obtained in said image sensing step; a dynamic range expansion step of combining the image data stored in said first storing step and generating image data of a single image of expanded dynamic range; a second storing step of storing the image data of the single image generated in said dynamic range expansion step; a clearing step of clearing the image data stored in said first storing step; a shifting step of shifting an image formation position of the images of the object on an image sensing device to a plurality of positions; a repeating step of repeating said image sensing step to said clearing step at each image formation position shifted by said shifting step and generating image data of a plurality of images of expanded dynamic range; and a combining step of combining the plurality of images of expanded dynamic range obtained in said repeating step and generating image data of a single image of high resolution.
