Abstract
A biological information detection device includes a light source, an image capturing device, and one or more arithmetic circuits. The light source projects dots formed by light onto a target including a living body. The image capturing device includes photodetector cells and generates an image signal representing an image of the target onto which the dots are projected. The one or more arithmetic circuits detect a portion corresponding to at least a part of the living body in the image by using the image signal and calculate biological information of the living body by using image signal of the portion.
Claims22
A biological information detection device comprising:
- a first light source that, in operation, projects first dots onto a target including a living body, the first dots being formed by first light;
- an image capturing device that, in operation, generates and outputs a first image signal representing a first image of the target onto which the first dots are projected, the image capturing device including first photodetector cells that, in operation, detect second light returning from the target onto which the first dots are projected;
- and
- one or more arithmetic circuits, wherein:
- the one or more arithmetic circuits, in operation, detect a first portion corresponding to at least a part of the living body in the first image by using the first image signal, and calculate biological information of the living body by using image signal of the first portion.
