IMAGE PROCESSING APPARATUS, IMAGE PROCESSING METHOD, AND NON-TRANSITORY COMPUTER READABLE STORAGE MEDIUM

摘要

An image processing apparatus which compares a first frame rate of a first moving image and a second frame rate of a second moving image each moving image having temporal scalability, converts a temporal hierarchical structure of the second moving image, when the first frame rate is higher than the second frame rate, by copying and inserting a picture included in a first temporal layer of the second moving image into a second temporal layer of the second moving image, and when the first frame rate is lower than the second frame rate, by discarding a picture, of pictures belonging to temporal layers of the second moving image, which belongs to a temporal layer with a frame rate higher than the first frame rate, and combines the first moving image with the converted second moving image.

1. An image processing apparatus comprising:
a processor; and a memory storing a program which, when executed by the processor, causes the image processing apparatus to: compare a frame rate of a first moving image and a frame rate of a second moving image, wherein each moving image has temporal scalability; convert a temporal hierarchical structure of the second moving image in accordance with the comparison result, wherein when the frame rate of the first moving image is higher than the frame rate of the second moving image, the temporal hierarchical structure of the second moving image is converted by copying and inserting a picture included in a first temporal layer of the second moving image into a second temporal layer of the second moving image, and when the frame rate of the first moving image is lower than the frame rate of the second moving image, the temporal hierarchical structure of the second moving image is converted by discarding a picture, of pictures belonging to temporal layers of the second moving image, which belongs to a temporal layer with a frame rate higher than the frame rate of the first moving image; and combine the first moving image with the converted second moving image.
