Patent ID: 7373022

Claim:
An apparatus for reproducing an image recorded with a difference between adjacent frames at at least one scene change point and a scaled-down image for identifying each scene change point, the image to be displayed on a screen of a display device, the apparatus comprising: a time-length-determining device operable to determine a length of time to display the scaled-down image, the length of time corresponding to a frame length of the display device screen; an image-number-determining device operable to determine a number of scaled-down images to be displayed during the length of time; a threshold-value-setting device operable to set a threshold value for the difference between adjacent frames, the difference being recorded during the length of time to allow a number of scaled-down images corresponding to the number of scaled-down images determined by the image-number-determining device to be extracted; and a controlling device operable to control operation of the display device to reproduce and display the scaled-down image corresponding to the at least one scene change point with the scaled-down image being synchronized with the image, the scaled-down image having a difference between adjacent frames of at least the threshold value.
