Title:
IMAGE PROCESSING APPARATUS, IMAGE PICKUP APPARATUS, METHOD AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2021/014764
Kind Code:
A1
Abstract:
Provided is an image pickup apparatus including a multi-band pass filter that selectively transmits band light in a specific band, a color filter that transmits the band light in the specific band per pixel of an image pickup device, the image pickup device that receives light transmitted by the multi-band pass filter and the color filter, and a signal processing section to which a pixel value of the image pickup device is input and which executes a signal process on the pixel value. The multi-band pass filter is configured to selectively transmit band light corresponding to a plurality of color filter elements, and the signal processing section generates a pixel value corresponding to a band, of a pixel to be processed using a raw image base pixel value signal per pixel and a spectral characteristic parameter of the image pickup apparatus.
