A moving image output device includes a moving image acquisition unit to acquire moving image data which represents a moving image as a collection of a plurality of images, a image generation unit to generate each piece of image data which represents each image of the moving image by processing the moving image data acquired by the moving image acquisition unit, an image output unit to sequentially output each piece of image data generated by the image generation unit according to a set time interval, and an interval setting unit to set to the image output unit a first time interval, and temporarily setting to the image output unit a second time interval which is longer than the first time interval as for image data for which the image generation by the image generation unit fails to occur in time with the sequential image output with the first time interval.
