Abstract
A caption detection device including a delay unit which delays a current-frame image to output a previous-frame image, a current feature detection unit which receives the current-frame image to detect a caption feature in each region, a previous feature detection unit which receives the previous-frame image from the delay unit to detect a caption feature in each region, a caption emergence region detection unit which detects a region where the caption emerges based on a temporal change between the feature in each region of the current-frame image and the feature in each region of the previous-frame image, and a caption disappearance region detection unit which detects a region where the caption disappears based on the temporal change between the feature in each region of the current-frame image from the current feature detection unit and the feature in each region of the previous-frame image.
