Title:
IMAGE INPUT DEVICE AND IMAGE INPUT METHOD
Document Type and Number:
WIPO Patent Application WO/2017/183191
Kind Code:
A1
Abstract:
Provided is an image input device that comprises: a scanning unit; a scanning signal obtaining unit; and an image-generating unit. The scanning unit moves a scanning point, which is a point where light from a light source is incident on a surface of a sample, in a reciprocating manner, and outputs a scanning period end signal that represents ending of the reciprocating scanning period. The scanning signal obtaining unit obtains an outward path scanning signal that represents the intensity of light reflected from the scanning point along the outward path, and a return path scanning signal that represents the intensity of light reflected from the scanning point along the return path. The image-generating unit obtains a shift amount between the outward path scanning signal and the return path scanning signal on the basis of the scanning period end signal, compensates for the shift between the outward path scanning signal and the return path scanning signal on the basis of the shift amount, and generates an image signal using the shift-compensated outward path scanning signal and return path scanning signal.
