Abstract: According to one embodiment, an image output device includes a buffer into which video information input in stream data is written per block, a determination unit configured to determine whether the buffer is in an overflow state due to slow reproduction, and a buffering control unit configured to switch a buffering pattern of the video information based on a determination result of the determination unit.

Abstract: A moving image player device of the present invention includes an interpolated image generating unit that generates an interpolated frame corresponding to a time between two adjacent input frames using two input frames among the plurality of input frames, and a video playing unit that detects a scene change in the video, outputs the plurality of input frames or the interpolated frames in time series based on the detection result, and plays the video at an arbitrary playing speed. When the scene change is detected, the video playing unit skips a display of the interpolated frames corresponding to time between an input frame at the end of a first scene and an input frame at the head of a second scene, and displays an input frame of the second scene or the interpolated frame after the input frame at the end of the first scene or the interpolated frame.

Abstract: According to a moving-image playback device of an embodiment of the invention, a frame rate control circuit uses an input interval Tc of a plurality of input images in an input video, a display interval Td of a plurality of display images in a display video, and a time extension magnification N of the display video with respect to the input video as inputs and that outputs the number “m” of images of the same content and a constant “n” greater by one than the number “a” of interpolation images which are each inserted between the input images. The frame rate control circuit outputs the number “m” of images and the constant “n”, which are determined based on a combination (m, n) of a natural number for satisfying an equation of n×m=N×Tc/Td, to the interpolation image generation circuit.
