Title: IMAGE PROCESSING DEVICE AND IMAGE PROCESSING METHOD
Abstract:
The present invention addresses the problem of ensuring the visibility of a description on a description portion hidden by a describer, in a state in which the positional relationship between the describer and the description on the description portion is maintained. Moving image data obtained by capturing an image of the describer making a description on the description portion are processed to determine a description part. Display data for displaying, as a description, each part determined to be a description part are generated and superimposed on the moving image data. For example, pixel-by-pixel difference values are extracted between a current frame image and a reference frame image, a group of successive pixels with the difference values more than or equal to a threshold value is recognized, and it is determined for each group whether the group is a description part.
