Title:
IMAGING DEVICE, VEHICULAR LAMP, VEHICLE, AND IMAGING METHOD
Document Type and Number:
WIPO Patent Application WO/2021/079811
Kind Code:
A1
Abstract:
An imaging device 100, wherein a distance measurement sensor 140 detects the distance d to a target TGT. An illumination device 110 sequentially irradiates reference light S1 having a spatially random intensity distribution. A photodetector 120 measures reflected light S2 from an object OBJ. A computation processing device 130 applies a window that corresponds to the output of the distance measurement device 140 to the output of the photodetector 120, calculates the correlation of the intensity distribution of the reference light and the detection intensity based on a component included in the window, and re-configures the restored image of the target.
