Title:
VIDEO COMPRESSION DEVICE, DETECTION DEVICE, VIDEO COMPRESSION PROGRAM, AND DETECTION PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/153680
Kind Code:
A1
Abstract:
The purpose of the present invention is to compress images captured of an object person while maintaining pulse wave information. A video transmission device 71 takes a picture of the face of an object person 70, and extracts a face region from the image data of said picture. Further, the video transmission device 71 reversibly compresses the image data of the face region while irreversibly compressing the image data of the regions other than the face, and then transmits the compressed image data to a detection device 81. Upon receipt of an image of the face region from the video transmission device 71, the detection device 81 decompresses said image, and restores the image of the face region without losing information. Then, the detection device 81 detects pulse waves from changes in the skin color of the object person 70 that is shown in the restored image of the face region. Furthermore, the image data of the regions other the face is also restored, and the images of the face region and the regions other the face are both displayed on a display device 86. Thus, the video transmission device 71 and the detection device 81 make it possible to cut back on the bandwidth required for video transmission while assuring the video image quality required for detection of pulse waves.
