1. A video quality estimation apparatus that estimates a video quality of a video having a screen layout in which parts are arranged, the video quality estimation apparatus comprising:
a processor; and
a memory storing program instructions that cause the processor to:
estimate a video quality of each of the parts forming the video; and
estimate the video quality of the video based on the estimated video quality of each of the parts and a layout resolution of each of the parts on the screen layout, said layout resolution being determined based on a relative size of each of the parts within a display,
wherein the program instructions cause the processor to:
calculate, for each of the parts, a video quality reflecting an influence of reduction in size of each of the parts to form the screen layout, said influence of reduction in size of each of the parts being defined by a degree of deterioration of the video quality, for each of the parts with different sizes, that is caused by reduction of bit rate; and
calculate the video quality of the video by reflecting an influence of integration of the plurality of parts forming the screen layout, said influence of the integration of the plurality of parts being defined by a degree of deterioration of the video quality that is caused by integrating video quality of each of the parts.
