Patent ID: 7450782

Claim:
An apparatus equipped with a camera, comprising: an image sensor for acquiring substantially identical images having different illumination degrees; a plurality of memories for storing the substantially identical images generated from the image sensor; an image controller for dividing each of the substantially identical images into a plurality of local images each having a predetermined size of at least larger than 1 pixel by 1 pixel, calculating a local variance value for each of the local images, the local variance value of a local image being derived from deviations of image data of image pixels of the local image from a mean value of the image data of the local image, comparing the calculated local variance values therebetween, assigning a high weight to a local image of one of the substantially identical images having a high variance value, assigning a low weight to a corresponding local image of another one of the substantially identical images having a low variance value, synthesizing the corresponding local images, and creating a reconstructed image; and a display for displaying the reconstructed image.
