BIOLOGICAL INFORMATION DETECTING DEVICE AND ELECTRONIC APPARATUS
First Claim
1. A biological information detecting device comprising:
- a first light receiving portion which receives light from a subject;
a second light receiving portion which receives light from a subject;
a processing portion; and
at least one light emitting portion which emits light to the subject,wherein when a distance between the light emitting portion and the first light receiving portion is set to L1 and a distance between the light emitting portion and the second light receiving portion is set to L2, L1<
L2 is satisfied,wherein the processing portion performs first body motion noise reduction processing that reduces a body motion noise of a first detection signal which is detected by the first light receiving portion based on a second detection signal which is detected by the second light receiving portion, andwherein the processing portion calculates biological information based on the first detection signal after the first body motion noise reduction processing.

Abstract
A biological information detecting device includes: a first light receiving portion and a second light receiving portion which receive light from a subject; a processing portion; and at least one light emitting portion (light emitting portion or the like) which emits light to the subject. When a distance between the light emitting portion and the first light receiving portion is set to L1 and a distance between the light emitting portion and the second light receiving portion is set to L2, L1<L2 is satisfied. The processing portion performs body motion noise reduction processing that reduces a body motion noise of a first detection signal which is detected by the first light receiving portion based on a second detection signal which is detected by the second light receiving portion, and calculates biological information based on the first detection signal after the body motion noise reduction processing.
