Title:
IMAGING DEVICE AND SIGNAL PROCESSING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/210197
Kind Code:
A1
Abstract:
An imaging device according to one aspect of the present disclosure comprises: a multispectral sensor unit, a narrowband signal generation unit, and a control unit. The multispectral sensor unit outputs a plurality of (N) wavelength signals as pixel signals. The narrowband signal generation unit uses a coefficient matrix to generate a plurality of (M (M>N)) narrowband signals narrower than the wavelength signals, from the plurality of wavelength signals output from the multispectral sensor. The control unit calculates an evaluation value by performing a weighted average process on a plurality of wavelength signals or a plurality of detection values generated using the plurality of wavelength signals, and performs exposure control on the multispectral sensor unit on the basis of the calculated evaluation value.
