Abstract
An image processing device includes: an image acquiring unit configured to acquire a plurality of images at different imaging time which images are captured when illumination light in different wavelength bands is emitted; and a processor including hardware. The processor is configured to generate a low-resolution image by lowering resolution of at least one image in the plurality of images, and detect light-absorption information at a certain depth based on a correlation between images which are in an image group including the low-resolution image and the plurality of images, which are captured with the illumination light in different wavelength bands, and at least one of which is the low-resolution image.

An image processing device comprising:
- an image acquiring unit configured to acquire a plurality of images at different imaging time which images are captured when illumination light in different wavelength bands is emitted;
- and
- a processor including hardware,
- wherein the processor is configured to
- generate a low-resolution image by lowering resolution of at least one image in the plurality of images, and
- detect light-absorption information at a certain depth based on a correlation between images which are in an image group including the low-resolution image and the plurality of images, which are captured with the illumination light in different wavelength bands, and at least one of which is the low-resolution image.
An image processing method comprising:
- acquiring a plurality of images at different imaging time which images are captured when illumination light in different wavelength bands is emitted;
- generating a low-resolution image by lowering resolution of at least one image in the plurality of images;
- and
- detecting light-absorption information at a certain depth based on a correlation between images which are in an image group including the low-resolution image and the plurality of images, which are captured with illumination light in different wavelength bands, and at least one of which is the low-resolution image.
A non-transitory computer-readable recording medium with an executable program stored thereon, the program causing an image processing device to execute:
- acquiring a plurality of images at different imaging time which images are captured when illumination light in different wavelength bands is emitted;
- generating a low-resolution image by lowering resolution of at least one image in the plurality of images;
- and
- detecting light-absorption information at a certain depth based a correlation between images which are in an image group including the low-resolution image and the plurality of images, which are captured with illumination light in different wavelength bands, and at least one of which is the low-resolution image.
