VIDEO DATA PROCESSING DEVICE AND METHOD |
摘要 |
A video data processing device includes: a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute: making, on the basis of first key frames obtained by encoding images in frames included in moving image data, difference frames in each of which a partial image different from an image in a frame corresponding to each first key frame is encoded; and generating, if the number of generated difference frames reaches a first number, in response to detection that a difference between a difference frame generated thereafter and a difference frame preceding in time to the difference frame generated thereafter is not larger than a given value, a second key frame distinguished from the first key frames and obtained by encoding an image in the frame. |

1. A video data processing device, comprising:
a processor; and a memory which stores a plurality of instructions, which when executed by the processor, cause the processor to execute: making, on the basis of first key frames obtained by encoding images in frames included in moving image data, difference frames in each of which a partial image different from an image in a frame corresponding to each first key frame is encoded; and generating, if the number of generated difference frames reaches a first number, in response to detection that a difference between a difference frame generated thereafter and a difference frame preceding in time to the difference frame generated thereafter is not larger than a given value, a second key frame distinguished from the first key frames and obtained by encoding an image in the frame. |
