Abstract
A color filter enhancement method for a portable digital image acquisition device includes digitally exposing color pixels of a color sensor array for a first digital exposure duration and digitally exposing white pixels of a color sensor array for a second digital exposure time shorter than the first digital exposure duration. A color filter enhanced digital image is generated using data from both the color pixels exposed for the first digital exposure duration and the white pixels exposed for the second digital exposure duration.
Claims27
A color filter enhancement method for a portable digital image acquisition device, comprising:
- (a) digitally exposing color pixels of a color sensor array for a first digital exposure duration;
- (b) digitally exposing white pixels of a color sensor array for a second digital exposure time shorter than the first digital exposure duration;
- (c) generating a color filter enhanced digital image using data from both the color pixels exposed for the first digital exposure duration and the white pixels exposed for the second digital exposure duration, including applying color information using data from the color pixels to a sharp grayscale image generated using data from the white pixels to generate a sharp color image, without de-blurring using motion estimation nor a point spread function (PSF);
- and
- (d) storing, transmitting, communicating, displaying, or projecting the color filter enhanced digital image or a further processed version, or combinations thereof.
A portable digital image acquisition device, comprising:
- (a) optics and a color sensor array for acquiring a color digital image;
- (b) a processor;
- (c) one or more processor-readable media having code embedded therein for programming the processor to perform a color filter enhancement method that comprises:
- (i) digitally exposing color pixels of the color sensor array for a first digital exposure duration;
- (ii) digitally exposing white pixels of the color sensor array for a second digital exposure time shorter than the first digital exposure duration;
- (iii) generating a color filter enhanced digital image using data from both the color pixels exposed for the first digital exposure duration and the white pixels exposed for the second digital exposure duration, including applying color information using data from the color pixels to a sharp grayscale image generated using data from the white pixels to generate a sharp color image, without de-blurring using motion estimation nor a point spread function (PSF);
- and
- (iv) storing, transmitting, communicating, displaying, or projecting the color filter enhanced digital image or a further processed version, or combinations thereof.
One or more non-transitory processor-readable media having code embedded therein for programming the processor to perform a color filter enhancement method that comprises:
- (a) digitally exposing color pixels of the color sensor array for a first digital exposure duration;
- (b) digitally exposing white pixels of the color sensor array for a second digital exposure time shorter than the first digital exposure duration;
- (c) generating a color filter enhanced digital image using data from both the color pixels exposed for the first digital exposure duration and the white pixels exposed for the second digital exposure duration, including applying color information using data from the color pixels to a sharp grayscale image generated using data from the white pixels to generate a sharp color image, without de-blurring using motion estimation nor a point spread function (PSF);
- and
- (d) storing, transmitting, communicating, displaying, or projecting the color filter enhanced digital image or a further processed version, or combinations thereof.
