QWhat is the form of provision?

A It is provided as software.

QWhat camera can I use?

A NIR camera.

QWhy is it possible to measure the pulse rate at night?

A This is achieved by irradiating NIR light and capturing the subject with a NIR camera.

QIs it also applicable to compressed video?

A Pulse rate cannot be calculated for lossy compressed video because pulse information is missing compared to the original video. In addition, image processing on the camera side may affect the pulse rate calculation.

QIs RRI available?

A Currently, only the pulse rate can be calculated.

Automatically monitors the driver's pulse rate using unique vital sensing technology.

Feature01

Contactless

By analyzing face image sequences captured by the camera, contactless pulse rate measurement is achieved.
Hemoglobin in the blood has the property of absorbing light. This changes the intensity of the light according to the heartbeat. VitalBit™ detects changes in NIR light and calculates pulse rate.

VitalBit™ mechanism
1) Determine the subject from the camera image by face detection.
2) Pulse information is detected from the face image.
3) Calculates pulse rate

Feature02

Measuring pulse rate at night

It is possible to measure pulse rate in a dark environment by irradiating the face with NIR light and photographing the face with NIR camera.
In general, NIR light has a worse S/N of the pulse signal than visible light, but VitalBit™ realizes the pulse rate measurement using the unique signal processing.

Usage example01

Driver monitoring system

Using VitalBit™, it is possible to measure pulse rate of the driver at night.
A single NIR camera can be used for both VitalBit™ and the driver monitoring system.
The function of VitalBit™ can be added without extra investment on hardware.
