Title:
IMAGE-CAPTURING DEVICE, SUBJECT DEPTH ESTIMATION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/079998
Kind Code:
A1
Abstract:
The present invention improves practicality in estimating subject depth through encoded imaging. A computation control unit 30: captures an encoded image of a subject 90 using a first imaging system 10 having a first field angle α; obtains a first captured image P1; detects a specific object 92 on the basis of the first captured image P1, the specific object 92 being included in the subject 90 and being at a distance equal to or greater than a threshold value from the first imaging system 10; captures an encoded image of the detected specific object 92 using a second imaging system 20 having a second field angle β that is narrower than the first field angle α; obtains a second captured image P2; decodes the first captured image P1 and the second captured image P2; and obtains depth information D1 pertaining to the subject 90 and depth information D2 pertaining to the specific object 92.
