摘要： The present invention relates to an image processing apparatus and method, a recording medium, and a program that can very sharply display video images which are subjected to frame rate conversion by suppressing a decrease in the image quality (blurred images) caused by imaging blur. A high frame converter 11 performs high frame rate conversion on an input moving picture. An imaging blur suppression processor 13 corrects each pixel value forming a subject frame based on at least one value corresponding to the subject frame of the parameter values representing imaging blur detected by an imaging blur characteristic detector 12. Accordingly, a moving picture having a higher rate than that of the input moving picture and having each pixel value suitably corrected to suppress imaging blur is output. The present invention is applicable to a television system.
