An apparatus includes: a processor configured to: execute temporal-scalable coding on input-video-image data at a first frame rate; convert the input-video-image data to video-image data of a second frame rate lower than the first frame rate; execute temporal-scalable coding on the video-image data of the second frame-rate and output a second encoding-complexity measure of a picture subjected to the temporal-scalable coding at the second frame-rate; correct, when the temporal-scalable coding is executed on the input-video-image data at the first frame-rate, a first encoding-complexity measure, estimated based on the second encoding-complexity of the picture and to be referenced for a picture to be encoded, of the picture to be encoded, based on a distance between the picture to be encoded and the picture to be referenced in a time direction; and execute the temporal-scalable coding on the input-video-image data at the first frame-rate based on the corrected first encoding-complexity measure.
