Title:
IMAGE ANALYSIS APPARATUS, PULSE WAVE DETECTION APPARATUS, AND IMAGE ANALYSIS METHOD
Document Type and Number:
Japanese Patent JP2022160891
Kind Code:
A
Abstract:
To improve detection accuracy of a pulse wave by a method different from conventional methods.SOLUTION: In an image analysis apparatus (10), a region of interest detection unit (11) detects a region of interest of a living body (900) from an image including the living body (900) based on a predetermined algorithm. A pulse wave detection unit (12) reduces an influence of a specific high-luminance pixel with a pixel value equal to or larger than a pixel value threshold in a plurality of pixels included in the region of interest and thereafter detects the pulse wave of the living body (900) based on the time change of the pixel values of the pixels.SELECTED DRAWING: Figure 1
