Title:
IMAGE DETERMINATION METHOD AND IMAGE DETERMINATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/024739
Kind Code:
A1
Abstract:
The present invention determines whether a captured image is a real captured image or a re-captured image. A control device obtains a first captured image which is generated by capturing an image of an image capture subject illuminated in accordance with a first light emission pattern, obtains a second captured image which is generated by capturing an image of the image capture subject illuminated in accordance with a second light emission pattern, calculates a first luminance value set and a second luminance value set for the pixels in the first captured image and the second captured image, calculates a differential value set from the first luminance value set and the second luminance value set, and determines the luminance distribution in the differential value set.
