SIGNAL PROCESSING DEVICE, SIGNAL PROCESSING METHOD, AND PROGRAM

WIPO Patent Application WO/2019/171984

A1

This technology relates to a signal processing device, a signal processing method, and a program which make it possible to easily estimate image distortion occurring when photographing is performed through a transmission body transmitting light. This signal processing device is provided with: a lens distortion estimation unit which, on the basis of the position of a feature point of a first image of a predetermined subject photographed by a photographing unit through a transmission body transmitting light and a lens, and the position of a feature point of a second image of the subject, the second image having neither transmission body distortion caused by the transmission body nor lens distortion caused by the lens, estimates the lens distortion; and a transmission body distortion estimation unit which, on the basis of the position of the feature point of the first image, and the position of a feature point of a third image obtained by removing the estimated lens distortion from the first image, estimates the transmission body distortion. This technology is applicable, for example, to a wearable device and a vehicle-mounted camera.
