Document Type and Number:
WIPO Patent Application WO/2017/094380
Kind Code:
A1
Abstract:
The present invention makes it possible to simply and efficiently obtain a speckle pattern contrast that is a prerequisite for fluid speed measurement. The present invention provides an information processing device provided with a brightness integration unit for integrating the brightnesses of a plurality of speckle images obtained by using a photography element to repeatedly photograph scattered light obtained from a photography subject irradiated with coherent light and a contrast calculation unit for calculating a speckle pattern contrast on the basis of a speckle integration image integrated by the brightness integration unit.
