IMAGE QUALITY ESTIMATION APPARATUS, METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To estimate an individual image quality value regarding object image communication using header information on an IP packet and a received image signal without referring to the content of a payload part of the IP packet.

SOLUTION: Difference between a video time information amount TIFcalculated from a captured object video signal and an average time information amount TIave corresponding to a coding information amount of an object image calculated from a captured IP packet is calculated as a differential time information amount ΔTI, a differential image quality value ΔV corresponding to the coding information amount of the object image is calculated from the differential time information amount ΔTI, the maximum differential image quality value and the minimum differential image quality value corresponding to the coding information amount of the object image, an average image quality value Vqe_ave corresponding to the coding information amount of the object image is corrected by the differential image quality value ΔV, and an estimated value of an subjective image quality regarding the object image is calculated as an individual image quality value Vqs.
