Document Type and Number:
Japanese Patent JP7012291
Kind Code:
B2
Abstract:
An image processing apparatus includes a processor including hardware. The processor is configured to: acquire video data; estimate a spatial distribution of a predetermined biological component for which a component spectrum temporally varies with respect to image data of a predetermined frame among a plurality of frames included in the video data; generate biological component video data in which the biological component is extracted from the video data based on the estimated spatial distribution of the biological component in the image data of the predetermined frame; and generate periodic variation video data of the biological component by applying, to the biological component video data, a filter for extracting a predetermined frequency component.
