<p>An electronic camera comprising a frame memory 6, which stores a digital picture data corresponding to a picture of one frame, and a multiple exposure control circuit 5, which controls multiple exposures. In response to a number of multiple exposures "m", wherein "m" is an integer of being greater than or equal to 2, the frame memory 6 has a memory capacity of "M" bits defined by an equation: M = (N + k x nPXL), wherein "N" is a necessary capacity in bit for a single exposure, "k" is an integer of satisfying an inequality 2<k-1><m</=2<k> and nPXL is a number of pixels in one picture frame. The digital picture data is integrated by the number of multiple exposures "m" with the multiple exposure control circuit 5 and stored in the frame memory 6, and then a value corresponding to each pixel of the picture data obtained by the integration is decreased by a factor of 1/m and outputted.</p> |
