Abstract:
1. An image synthesizing apparatus, comprising: an image frames memory which stores a plurality of image frames which are produced by continuously taking pictures of a subject; an image synthesizer which synthesizes the plurality of image frames to a summation image; an image brightness adjuster which adjusts a brightness of the summation image by synthesizing the image frames with the image synthesizer; a display which displays the summation image which is being synthesized by the image synthesizer in image brightness adjusting processing by the image brightness adjuster; and a tone correcting parameter changer which changes a tone correcting parameter used in the image brightness adjusting processing; wherein the image brightness adjuster executes the image brightness adjusting processing such that the entire summation image is gradually brightened as a number of the synthesized image frames is increased before the tone correcting parameter is changed by the tone correcting parameter changer, and executes the image brightness adjusting processing such that only a dark portion in the summation image is gradually brightened as the number of the synthesized image frames is increased after the tone correcting parameter is changed by the tone correcting parameter changer.
