Abstract
A method for reducing motion artifacts and the systems for implementing the same are provided. The method includes receiving a full-resolution image at a first time point; extracting a first partial-resolution image from the full-resolution image; and calculating a second partial-resolution image for a second time point after the first time point. The first and the second partial-resolution images are complementary.
Claims15
A method for processing images, the method comprising:
- receiving first and second full-resolution images corresponding to first and second time points for consecutive display during first and second display time intervals at a given frame rate;
- extracting a first partial-resolution image from one of the first and second full-resolution images;
- from the first and second full-resolution images, calculating a second partial-resolution image corresponding to a third time point intermediate the first and second time points, wherein the first and the second partial-resolution images are complementary;
- and
- displaying the first and second partial-resolution images successively at different times during the first display time interval.

An image processing system comprising:
- an input for receiving first and second full-resolution images corresponding to first and second time points for consecutive display during first and second display time intervals at a given frame rate;
- a partial-resolution image extractor configured to extract a first partial-resolution image from one of the first and second full resolution images;
- a partial-resolution image calculator configured to calculate, from the first and second full-resolution images, a second partial-resolution image complementary to the first partial-resolution image, wherein the second partial-resolution image corresponds to a third time point intermediate the first and second time points;
- and
- an output outputting the first and second partial-resolution images for displaying the first and second partial-resolution images successively at different times during the first display time interval.

A method comprising:
- receiving a series of consecutive full-resolution image frames at a given frame rate, the received image frames including a first image frame F0 received at a first time T0 and a second image frame F1 received at a second time T1, each received image frame including pixel imaging data for display of respective pixels in a full-resolution image having a row×column pixel array;
- extracting a first partial-resolution image from one of the first or second image frames by masking ones of pixels separated and leaving others of pixels unmasked in each row and column for that frame;
- using pixel imaging data of the first and second image frames F0 and F1, calculating a third image frame including pixel imaging data for display of respective pixels in a full-resolution image having a row×column pixel array corresponding to an image representing picture subject matter and position at a third time, intermediate the first and second times T0 and T1;
- extracting a second partial-resolution image from the third image frame by masking pixels corresponding to pixels left unmasked in the first partial-resolution image and leaving unmasked pixels corresponding to pixels masked in the first partial-resolution image;
- and
- displaying the first and second partial-resolution images successively at different times greater than the given frame rate, with unmasked pixels of the first and third image frames being displayed according to their pixel imaging data and masked pixels of the first and third frames not being displayed.
