Title:
IMAGE ACQUISITION DEVICE AND IMAGE ACQUISITION METHOD
Document Type and Number:
WIPO Patent Application WO/2017/169597
Kind Code:
A1
Abstract:
This image acquisition device 1 is provided with a spatial optical modulator 11, an optical scanner 14, a detection unit 32, a control unit 70 and so forth. The spatial optical modulator 11 irradiates a plurality of irradiation areas on the surface or inside of a subject to be observed S with focused modulated excitation light. The detection unit 32 has on the light receiving plane thereof a plurality of imaging areas that establishes an imaging relationship with the plurality of irradiation areas of the subject to be observed through an imaging optical system. Each of the plurality of imaging areas corresponds to one or more pixels, and pixels that correspond to none of the plurality of imaging areas exist adjacent to each imaging area. The control unit 70 corrects the detection signal of a pixel corresponding to each imaging area on the basis of the detection signal of a pixel that exists adjacent to the imaging area and corresponds to none of the plurality of imaging areas, and creates an image of the observed subject on the basis of the corrected detection signal. This makes it possible to achieve an image acquisition device and an image acquisition method with which the SN ratio of an observed subject image generated by multi-point scanning can be easily improved.
