发明名称 APPARATUS AND METHOD FOR GENERATING THUMBNAIL IMAGES
摘要 The present invention discloses an apparatus for automatically generating thumbnail images for a video browser and a video recording and reproducing device, and a method therefor. A difference between histograms of two DC images of a current frame I picture and a previous frame I picture is calculated and compared with a predetermined reference value for deciding a stabilization section. When the difference between the histograms of the current I picture DC image and the previous I picture DC image does not exceed the reference value, the corresponding I picture DC image is outputted as the thumbnail image. Here, a blank test is executed to exclude a dark original image whose contents are indistinguishable. Only the DC image of the I picture passing through the blank test is outputted as the thumbnail image.
