Abstract
An apparatus is described. The apparatus includes a digital camera that is capable of shooting at least two images at different effective lens focal lengths. The camera is also capable of high pass filtering (HP) said at least two images, estimating respective spectral densities (SD) of said at least two filtered images and then low pass filtering (LP) the respective estimates of said at least two filtered images prior to combining said at least two images into a single image to produce one or more optical effects.

An apparatus comprising a digital camera configured to shoot at least two images at different effective lens focal lengths, said camera further being configured to:
- high-pass filter corresponding copies of each of said at least two images;
- estimate respective spectral densities (SD) of said at least two high-pass filtered images;
- and
- low-pass filter the respective SD estimates of said at least two high-pass filtered images, and
- combine said at least two images into a single image, based on information from said low-pass filtered respective SD estimates, to produce one or more optical effects.
An apparatus for capturing digital signal values for one or more digital images comprising:
- an image capture device configured to capture multiple images of a scene of interest being produced with varying focal lengths and said image capture device further being configured to high-pass filter corresponding copies of each of said multiple images, produce spectral density estimates of said multiple high-pass filtered images, low-pass filter said spectral density estimates, and combine said multiple images into a single image, based on information from said low-pass filtered spectral density estimates.
A method comprising:
- shooting at least two images at different effective lens focal lengths;
- high pass filtering (HP) corresponding copies of each of said at least two images;
- estimating respective spectral densities (SD) of said at least two high-pass filtered images;
- and
- low pass filtering (LP) the respective SD estimates of said at least two high-pass filtered images prior to combining said at least two images into a single image to produce one or more optical effects.
An apparatus comprising:
- means for shooting at least two images at different effective lens focal lengths;
- means for high pass filtering (HP) corresponding copies of each of said at least two images;
- means for estimating respective spectral densities (SD) of said at least two high-pass filtered images;
- means for low pass filtering (LP) the respective SD estimates of said at least two high-pass filtered images;
- and
- means for combining said at least two images into a single image, based on information from said low-pass filtered respective SD estimates, to produce one or more optical effects.
A non-transitory processor-readable medium having stored thereon instructions capable of being executed by a special purpose computing platform to:
- shoot at least two images at different effective lens focal lengths;
- high pass filter (HP) corresponding copies of each of said at least two images;
- estimate respective spectral densities (SD) of said at least two high-pass filtered images;
- and
- low pass filter (LP) the respective SD estimates of said at least two high-pass filtered images, and
- combine said at least two images into a single image, based on information from said low-pass filtered respective SD estimates, to produce one or more optical effects.
