1. A Virtual Reality (VR) video encoding parameter calculation device comprising one or more processors configured to perform operations comprising:
calculating an overall quality estimation value of a VR video for each encoding parameter included in a plurality of encoding parameters, wherein calculating the overall quality estimation value of the VR video for an encoding parameter comprises:
calculating (i) a quality estimation value of a high image quality region in the VR video and (ii) a quality estimation value of a low image quality region in the VR video,
calculating a degree of contribution of quality of the high image quality region and quality of the low image quality region to the overall quality estimation value, and
calculating the overall quality estimation value based on the degree of contribution, the quality estimation value of the high image quality region, and the quality estimation value of the low image quality region; and
extracting, from the plurality of encoding parameters, an encoding parameter corresponding to the overall quality estimation value that satisfies given target quality.
