Abstract:
Methods for generating a synthesized image with increased depth of field from a sequence of real-time frames received by varying-range focusing using liquid optics are investigated. An algorithm based on constructing a map of ranges by analyzing a contrast pyramid and the weighed pixel-by-pixel summation of the initial images whose coefficients are proportional to the number of same-range pixels in each local neighborhood is developed.

Keywords:
electrically controlled lens, liquid lens, increased depth of field, fusion algorithm, image reconstruction-restoration, image processing.
