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.
