US patent US12749158

Apparatus and method for enhancing a whiteboard image

Abstract

An image processing apparatus is provided and is configured to generate a second corrected image by using an average first corrected images, extracting one or more regions of the average first corrected images indicative of motion in the exacted image data; combining the extracted one or more regions with the first corrected image; generate a binary mask of the second corrected image, the binary mask having a region indicative of motion replaced using an average of a predetermined number of binary masks; generate a filtered image based on the binary mask of the second corrected image and the second corrected image; generate a third corrected image by performing second image correction processing on the filtered image; and perform blending processing that combines the third corrected image with the first corrected image to generate a final corrected image.
