ABSTRACT:
An apparatus reproduces an image recorded with a difference between adjacent frames at at least one scene change point and scaled-down images for identifying each scene change point. A time-length-determining device determines the length of time to display the scaled-down images, the length of time corresponding to the frame length of a screen of a display device in which the image is displayed. An image-number-determining device determines the number of scaled-down images to be displayed during the length of time. A threshold-value-setting device sets a threshold value for the differences 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. A controlling device controls operations 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.
