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.

摘要： A histogram section determines as a motion vector at a pixel of interest the candidate motion vector with highest frequency from among a candidate motion vector at the pixel of interest and candidate motion vectors at pixels neighboring the pixel of interest supplied by a template matching section, and supplies it to a motion-vector correcting section. The motion-vector correction section evaluates the confidence level of the motion vector supplied by the histogram section based on the luminance gradient around the pixel of interest detected by a luminance-gradient detecting section and a control signal indicating whether correction should be carried out supplied by the template matching section. If it is determined that the confidence level of the motion vector is low, the motion vector is corrected.
