Document Type and Number:
WIPO Patent Application WO/2021/181775
Kind Code:
A1
Abstract:
A video processing device (100) is provided with a light irradiation unit (11), a video acquisition unit (31), a motion detection unit (33), and an imaging control unit (34). The light irradiation unit (11) irradiates the face of a subject with light. The video acquisition unit (31) acquires video obtained by capturing an image of the face of the subject. The motion detection unit (33) detects the speed of the motion of at least part of the face from the video acquired by the video acquisition unit (31). The imaging control unit (34) changes the open period of a shutter in the video acquisition unit (31) and the intensity of light emission by the light irradiation unit (11) on the basis of the speed detected by the motion detection unit (33).
