A moving image reproducing apparatus includes a moving image obtaining part which obtains first moving image data having, luminance data representing luminance of an image, and color data representing color of the image, a color data reduction part which generates second moving image data having the same luminance data as the luminance data of the first moving image data and color data whose data volume is reduced, by reducing a data volume of the color data of the first moving image data, a moving image generation part which generates third moving image data for moving image display, on the basis of the second moving image data, and a moving image output part which outputs the third moving image data.
