A moving image distribution server acquires in series a rendered screen, viewpoint information used for rendering the screen, and a depth buffer corresponding to the screen. It sets a evaluation pixel for each of the blocks that it divided a first screen into, and specifies a screen coordinate and a depth value, in a second screen acquired before the first screen, for a rendering object rendered on the evaluation pixel. Also, it compares a depth value of the screen coordinate and the depth value of the rendering object rendered on the evaluation pixel, and determines that inter-frame coding will be performed with the second screen for a block for which the 2 depth values are considered to be the same. Then, it transmits, to a external device, coding details information including the viewpoint information used for rendering of the first screen, the depth buffer corresponding to the first screen, and information indicating whether or not blocks of the first screen are to be inter-frame coded. |
